+# WELCOME TO SQUID 3.1.20
+# ----------------------------
+#
+# This is the documentation for the Squid configuration file.
+# This documentation can also be found online at:
+# http://www.squid-cache.org/Doc/config/
+#
+# You may wish to look at the Squid home page and wiki for the
+# FAQ and other documentation:
+# http://www.squid-cache.org/
+# http://wiki.squid-cache.org/SquidFaq
+# http://wiki.squid-cache.org/ConfigExamples
+#
+# This documentation shows what the defaults for various directives
+# happen to be. If you don't need to change the default, you should
+# leave the line out of your squid.conf in most cases.
+#
+# In some cases "none" refers to no default setting at all,
+# while in other cases it refers to the value of the option
+# - the comments for that keyword indicate if this is the case.
+#
+
+# Configuration options can be included using the "include" directive.
+# Include takes a list of files to include. Quoting and wildcards are
+# supported.
+#
+# For example,
+#
+# include /path/to/included/file/squid.acl.config
+#
+# Includes can be nested up to a hard-coded depth of 16 levels.
+# This arbitrary restriction is to prevent recursive include references
+# from causing Squid entering an infinite loop whilst trying to load
+# configuration files.
+
+# TAG: dns_testnames
+# Remove this line. DNS is no longer tested on startup.
+#Default:
+# none
+
+# TAG: extension_methods
+# Remove this line. All valid methods for HTTP are accepted by default.
+#Default:
+# none
+
+# TAG: incoming_rate

+
+# TAG: server_http11
+# Remove this line. HTTP/1.1 is supported by default.

+
+# OPTIONS FOR AUTHENTICATION
+# -----------------------------------------------------------------------------
+
+# TAG: auth_param
+# This is used to define parameters for the various authentication
+# schemes supported by Squid.
+#
+# format: auth_param scheme parameter [setting]
+#
+# The order in which authentication schemes are presented to the client is
+# dependent on the order the scheme first appears in config file. IE
+# has a bug (it's not RFC 2617 compliant) in that it will use the basic
+# scheme if basic is the first entry presented, even if more secure
+# schemes are presented. For now use the order in the recommended
+# settings section below. If other browsers have difficulties (don't
+# recognize the schemes offered even if you are using basic) either
+# put basic first, or disable the other schemes (by commenting out their
+# program entry).
+#
+# Once an authentication scheme is fully configured, it can only be
+# shutdown by shutting squid down and restarting. Changes can be made on
+# the fly and activated with a reconfigure. I.E. You can change to a
+# different helper, but not unconfigure the helper completely.
+#
+# Please note that while this directive defines how Squid processes
+# authentication it does not automatically activate authentication.
+# To use authentication you must in addition make use of ACLs based
+# on login name in http_access (proxy_auth, proxy_auth_regex or
+# external with %LOGIN used in the format tag). The browser will be
+# challenged for authentication on the first such acl encountered
+# in http_access processing and will also be re-challenged for new
+# login credentials if the request is being denied by a proxy_auth
+# type acl.
+#
+# WARNING: authentication can't be used in a transparently intercepting
+# proxy as the client then thinks it is talking to an origin server and
+# not the proxy. This is a limitation of bending the TCP/IP protocol to
+# transparently intercepting port 80, not a limitation in Squid.
+# Ports flagged 'transparent', 'intercept', or 'tproxy' have
+# authentication disabled.
+#
+# === Parameters for the basic scheme follow. ===
+#
+# "program" cmdline
+# Specify the command for the external authenticator. Such a program
+# reads a line containing "username password" and replies "OK" or
+# "ERR" in an endless loop. "ERR" responses may optionally be followed
+# by a error description available as %m in the returned error page.
+# If you use an authenticator, make sure you have 1 acl of type
+# proxy_auth.
+#
+# By default, the basic authentication scheme is not used unless a
+# program is specified.
+#
+# If you want to use the traditional NCSA proxy authentication, set
+# this line to something like
+#
+# auth_param basic program /usr/lib/squid3/ncsa_auth /usr/etc/passwd
+#
+# "utf8" on|off
+# HTTP uses iso-latin-1 as characterset, while some authentication
+# backends such as LDAP expects UTF-8. If this is set to on Squid will
+# translate the HTTP iso-latin-1 charset to UTF-8 before sending the
+# username & password to the helper.
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn. If you start too few
+# Squid will have to wait for them to process a backlog of credential
+# verifications, slowing it down. When password verifications are
+# done via a (slow) network you are likely to need lots of
+# authenticator processes.
+# auth_param basic children 5
+#
+# "concurrency" concurrency
+# The number of concurrent requests the helper can process.
+# The default of 0 is used for helpers who only supports
+# one request at a time. Setting this changes the protocol used to
+# include a channel number first on the request/response line, allowing
+# multiple requests to be sent to the same helper in parallell without
+# wating for the response.
+# Must not be set unless it's known the helper supports this.
+# auth_param basic concurrency 0
+#
+# "realm" realmstring
+# Specifies the realm name which is to be reported to the
+# client for the basic proxy authentication scheme (part of
+# the text the user will see when prompted their username and
+# password). There is no default.
+# auth_param basic realm Squid proxy-caching web server
+#
+# "credentialsttl" timetolive
+# Specifies how long squid assumes an externally validated
+# username:password pair is valid for - in other words how
+# often the helper program is called for that user. Set this
+# low to force revalidation with short lived passwords. Note
+# setting this high does not impact your susceptibility
+# to replay attacks unless you are using an one-time password
+# system (such as SecureID). If you are using such a system,
+# you will be vulnerable to replay attacks unless you also
+# use the max_user_ip ACL in an http_access rule.
+#
+# "casesensitive" on|off
+# Specifies if usernames are case sensitive. Most user databases are
+# case insensitive allowing the same username to be spelled using both
+# lower and upper case letters, but some are case sensitive. This
+# makes a big difference for user_max_ip ACL processing and similar.
+# auth_param basic casesensitive off
+#
+# === Parameters for the digest scheme follow ===
+#
+# "program" cmdline
+# Specify the command for the external authenticator. Such
+# a program reads a line containing "username":"realm" and
+# replies with the appropriate H(A1) value hex encoded or
+# ERR if the user (or his H(A1) hash) does not exists.
+# See rfc 2616 for the definition of H(A1).
+# "ERR" responses may optionally be followed by a error description
+# available as %m in the returned error page.
+#
+# By default, the digest authentication scheme is not used unless a
+# program is specified.
+#
+# If you want to use a digest authenticator, set this line to
+# something like
+#
+# auth_param digest program /usr/lib/squid3/digest_pw_auth /usr/etc/digpass
+#
+# "utf8" on|off
+# HTTP uses iso-latin-1 as characterset, while some authentication
+# backends such as LDAP expects UTF-8. If this is set to on Squid will
+# translate the HTTP iso-latin-1 charset to UTF-8 before sending the
+# username & password to the helper.
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to
+# process a backlog of H(A1) calculations, slowing it down.
+# When the H(A1) calculations are done via a (slow) network
+# you are likely to need lots of authenticator processes.
+# auth_param digest children 5
+#
+# "realm" realmstring
+# Specifies the realm name which is to be reported to the
+# client for the digest proxy authentication scheme (part of
+# the text the user will see when prompted their username and
+# password). There is no default.
+# auth_param digest realm Squid proxy-caching web server
+#
+# "nonce_garbage_interval" timeinterval
+# Specifies the interval that nonces that have been issued
+# to client_agent's are checked for validity.
+#
+# "nonce_max_duration" timeinterval
+# Specifies the maximum length of time a given nonce will be
+# valid for.
+#
+# "nonce_max_count" number
+# Specifies the maximum number of times a given nonce can be
+# used.
+#
+# "nonce_strictness" on|off
+# Determines if squid requires strict increment-by-1 behavior
+# for nonce counts, or just incrementing (off - for use when
+# useragents generate nonce counts that occasionally miss 1
+# (ie, 1,2,4,6)). Default off.
+#
+# "check_nonce_count" on|off
+# This directive if set to off can disable the nonce count check
+# completely to work around buggy digest qop implementations in
+# certain mainstream browser versions. Default on to check the
+# nonce count to protect from authentication replay attacks.
+#
+# "post_workaround" on|off
+# This is a workaround to certain buggy browsers who sends
+# an incorrect request digest in POST requests when reusing
+# the same nonce as acquired earlier on a GET request.
+#
+# === NTLM scheme options follow ===
+#
+# "program" cmdline
+# Specify the command for the external NTLM authenticator.
+# Such a program reads exchanged NTLMSSP packets with
+# the browser via Squid until authentication is completed.
+# If you use an NTLM authenticator, make sure you have 1 acl
+# of type proxy_auth. By default, the NTLM authenticator_program
+# is not used.
+#
+# auth_param ntlm program /usr/lib/squid3/ntlm_auth
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to
+# process a backlog of credential verifications, slowing it
+# down. When credential verifications are done via a (slow)
+# network you are likely to need lots of authenticator
+# processes.
+#
+# auth_param ntlm children 5
+#
+# "keep_alive" on|off
+# Whether to keep the connection open after the initial response where
+# Squid tells the browser which schemes are supported by the proxy.
+# Some browsers are known to present many login popups or to corrupt
+# POST/PUT requests transfer if the connection is not closed.
+# The default is currently OFF to avoid this, but may change.
+#
+# auth_param ntlm keep_alive on
+#
+# === Options for configuring the NEGOTIATE auth-scheme follow ===
+#
+# "program" cmdline
+# Specify the command for the external Negotiate authenticator.
+# This protocol is used in Microsoft Active-Directory enabled setups with
+# the Microsoft Internet Explorer or Mozilla Firefox browsers.
+# Its main purpose is to exchange credentials with the Squid proxy
+# using the Kerberos mechanisms.
+# If you use a Negotiate authenticator, make sure you have at least
+# one acl of type proxy_auth active. By default, the negotiate
+# authenticator_program is not used.
+# The only supported program for this role is the ntlm_auth
+# program distributed as part of Samba, version 4 or later.
+#
+# auth_param negotiate program /usr/lib/squid3/ntlm_auth --helper-protocol=gss-spnego
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to
+# process a backlog of credential verifications, slowing it
+# down. When crendential verifications are done via a (slow)
+# network you are likely to need lots of authenticator
+# processes.
+# auth_param negotiate children 5
+#
+# "keep_alive" on|off
+# Whether to keep the connection open after the initial response where
+# Squid tells the browser which schemes are supported by the proxy.
+# Some browsers are known to present many login popups or to corrupt
+# POST/PUT requests transfer if the connection is not closed.
+# The default is currently OFF to avoid this, but may change.
+#
+# auth_param negotiate keep_alive on
+#
+#
+# Examples:
+#
+##Recommended minimum configuration per scheme:
+##auth_param negotiate program <uncomment and complete this line to activate>
+##auth_param negotiate children 5

+##
+##auth_param basic program <uncomment and complete this line>
+##auth_param basic children 5
+##auth_param basic realm Squid proxy-caching web server
+##auth_param basic credentialsttl 2 hours
+#Default:

+
+# TAG: authenticate_cache_garbage_interval
+# The time period between garbage collection across the username cache.
+# This is a tradeoff between memory utilization (long intervals - say
+# 2 days) and CPU (short intervals - say 1 minute). Only change if you
+# have good reason to.
+#Default:
+# authenticate_cache_garbage_interval 1 hour
+
+# TAG: authenticate_ttl
+# The time a user & their credentials stay in the logged in
+# user cache since their last request. When the garbage
+# interval passes, all user credentials that have passed their
+# TTL are removed from memory.
+#Default:
+# authenticate_ttl 1 hour
+
+# TAG: authenticate_ip_ttl
+# If you use proxy authentication and the 'max_user_ip' ACL,
+# this directive controls how long Squid remembers the IP
+# addresses associated with each user. Use a small value
+# (e.g., 60 seconds) if your users might change addresses
+# quickly, as is the case with dialups. You might be safe
+# using a larger value (e.g., 2 hours) in a corporate LAN
+# environment with relatively static address assignments.
+#Default:
+# authenticate_ip_ttl 0 seconds
+

+# OK/ERR keyword=value ...
+#
+# Defined keywords:
+#
+# user= The users name (login)
+# password= The users password (for login= cache_peer option)
+# message= Message describing the reason. Available as %o
+# in error pages
+# tag= Apply a tag to a request (for both ERR and OK results)
+# Only sets a tag, does not alter existing tags.
+# log= String to be logged in access.log. Available as
+# %ea in logformat specifications
+#
+# If protocol=3.0 (the default) then URL escaping is used to protect
+# each value in both requests and responses.
+#
+# If using protocol=2.5 then all values need to be enclosed in quotes
+# if they may contain whitespace, or the whitespace escaped using \.
+# And quotes or \ characters within the keyword value must be \ escaped.
+#
+# When using the concurrency= option the protocol is changed by
+# introducing a query channel tag infront of the request/response.
+# The query channel tag is a number between 0 and concurrency-1.

+# TAG: follow_x_forwarded_for
+# Allowing or Denying the X-Forwarded-For header to be followed to
+# find the original source of a request.
+#
+# Requests may pass through a chain of several other proxies
+# before reaching us. The X-Forwarded-For header will contain a
+# comma-separated list of the IP addresses in the chain, with the
+# rightmost address being the most recent.
+#
+# If a request reaches us from a source that is allowed by this
+# configuration item, then we consult the X-Forwarded-For header
+# to see where that host received the request from. If the
+# X-Forwarded-For header contains multiple addresses, we continue
+# backtracking until we reach an address for which we are not allowed
+# to follow the X-Forwarded-For header, or until we reach the first
+# address in the list. For the purpose of ACL used in the
+# follow_x_forwarded_for directive the src ACL type always matches
+# the address we are testing and srcdomain matches its rDNS.
+#
+# The end result of this process is an IP address that we will
+# refer to as the indirect client address. This address may
+# be treated as the client address for access control, ICAP, delay
+# pools and logging, depending on the acl_uses_indirect_client,

+#
+# Any host for which we follow the X-Forwarded-For header

+# hosts to bypass any access control restrictions that are
+# based on the client's source addresses.

+#
+# To operate with tcp_outgoing_address and keep the bridging benefits
+# an additional ACL needs to be used which ensures the IPv6-bound traffic
+# is never forced or permitted out the IPv4 interface.
+#
+# # IPv6 destination test along with a dummy access control to perform the required DNS
+# # This MUST be place before any ALLOW rules.

+#
+# 'dst ipv6' is a slow ACL. It will only work here if 'dst' is used

+# -----------------------------------------------------------------------------
+
+# TAG: cache_peer
+# To specify other caches in a hierarchy, use the format:
+#
+# cache_peer hostname type http-port icp-port [options]
+#
+# For example,
+#
+# # proxy icp
+# # hostname type port port options
+# # -------------------- -------- ----- ----- -----------
+# cache_peer parent.foo.net parent 3128 3130 default
+# cache_peer sib1.foo.net sibling 3128 3130 proxy-only
+# cache_peer sib2.foo.net sibling 3128 3130 proxy-only
+# cache_peer example.com parent 80 0 default
+# cache_peer cdn.example.com sibling 3128 0
+#
+# type: either 'parent', 'sibling', or 'multicast'.
+#
+# proxy-port: The port number where the peer accept HTTP requests.
+# For other Squid proxies this is usually 3128
+# For web servers this is usually 80
+#
+# icp-port: Used for querying neighbor caches about objects.
+# Set to 0 if the peer does not support ICP or HTCP.
+# See ICP and HTCP options below for additional details.
+#
+#
+# ==== ICP OPTIONS ====
+#
+# You MUST also set icp_port and icp_access explicitly when using these options.
+# The defaults will prevent peer traffic using ICP.
+#
+#
+# no-query Disable ICP queries to this neighbor.
+#
+# multicast-responder
+# Indicates the named peer is a member of a multicast group.
+# ICP queries will not be sent directly to the peer, but ICP
+# replies will be accepted from it.
+#
+# closest-only Indicates that, for ICP_OP_MISS replies, we'll only forward
+# CLOSEST_PARENT_MISSes and never FIRST_PARENT_MISSes.
+#
+# background-ping
+# To only send ICP queries to this neighbor infrequently.
+# This is used to keep the neighbor round trip time updated
+# and is usually used in conjunction with weighted-round-robin.
+#
+#
+# ==== HTCP OPTIONS ====
+#
+# You MUST also set htcp_port and htcp_access explicitly when using these options.
+# The defaults will prevent peer traffic using HTCP.
+#
+#
+# htcp Send HTCP, instead of ICP, queries to the neighbor.
+# You probably also want to set the "icp-port" to 4827
+# instead of 3130.
+#
+# htcp-oldsquid Send HTCP to old Squid versions.
+#
+# htcp-no-clr Send HTCP to the neighbor but without
+# sending any CLR requests. This cannot be used with
+# htcp-only-clr.
+#
+# htcp-only-clr Send HTCP to the neighbor but ONLY CLR requests.
+# This cannot be used with htcp-no-clr.
+#
+# htcp-no-purge-clr
+# Send HTCP to the neighbor including CLRs but only when
+# they do not result from PURGE requests.
+#
+# htcp-forward-clr
+# Forward any HTCP CLR requests this proxy receives to the peer.
+#
+#
+# ==== PEER SELECTION METHODS ====
+#
+# The default peer selection method is ICP, with the first responding peer
+# being used as source. These options can be used for better load balancing.
+#
+#
+# default This is a parent cache which can be used as a "last-resort"
+# if a peer cannot be located by any of the peer-selection methods.
+# If specified more than once, only the first is used.
+#
+# round-robin Load-Balance parents which should be used in a round-robin
+# fashion in the absence of any ICP queries.
+# weight=N can be used to add bias.
+#
+# weighted-round-robin
+# Load-Balance parents which should be used in a round-robin
+# fashion with the frequency of each parent being based on the
+# round trip time. Closer parents are used more often.
+# Usually used for background-ping parents.
+# weight=N can be used to add bias.
+#
+# carp Load-Balance parents which should be used as a CARP array.
+# The requests will be distributed among the parents based on the
+# CARP load balancing hash function based on their weight.
+#
+# userhash Load-balance parents based on the client proxy_auth or ident username.
+#
+# sourcehash Load-balance parents based on the client source IP.
+#
+# multicast-siblings
+# To be used only for cache peers of type "multicast".
+# ALL members of this multicast group have "sibling"
+# relationship with it, not "parent". This is to a multicast
+# group when the requested object would be fetched only from
+# a "parent" cache, anyway. It's useful, e.g., when
+# configuring a pool of redundant Squid proxies, being
+# members of the same multicast group.
+#
+#
+# ==== PEER SELECTION OPTIONS ====
+#
+# weight=N use to affect the selection of a peer during any weighted
+# peer-selection mechanisms.
+# The weight must be an integer; default is 1,
+# larger weights are favored more.
+# This option does not affect parent selection if a peering
+# protocol is not in use.
+#
+# basetime=N Specify a base amount to be subtracted from round trip
+# times of parents.
+# It is subtracted before division by weight in calculating
+# which parent to fectch from. If the rtt is less than the
+# base time the rtt is set to a minimal value.
+#
+# ttl=N Specify a TTL to use when sending multicast ICP queries
+# to this address.
+# Only useful when sending to a multicast group.
+# Because we don't accept ICP replies from random
+# hosts, you must configure other group members as
+# peers with the 'multicast-responder' option.
+#
+# no-delay To prevent access to this neighbor from influencing the
+# delay pools.
+#
+# digest-url=URL Tell Squid to fetch the cache digest (if digests are
+# enabled) for this host from the specified URL rather
+# than the Squid default location.
+#
+#
+# ==== ACCELERATOR / REVERSE-PROXY OPTIONS ====
+#
+# originserver Causes this parent to be contacted as an origin server.
+# Meant to be used in accelerator setups when the peer
+# is a web server.
+#
+# forceddomain=name
+# Set the Host header of requests forwarded to this peer.
+# Useful in accelerator setups where the server (peer)
+# expects a certain domain name but clients may request
+# others. ie example.com or www.example.com
+#
+# no-digest Disable request of cache digests.
+#
+# no-netdb-exchange
+# Disables requesting ICMP RTT database (NetDB).
+#
+#
+# ==== AUTHENTICATION OPTIONS ====
+#
+# login=user:password
+# If this is a personal/workgroup proxy and your parent
+# requires proxy authentication.
+#
+# Note: The string can include URL escapes (i.e. %20 for
+# spaces). This also means % must be written as %%.
+#
+# login=PROXYPASS
+# Send login details received from client to this peer.
+# Authentication is not required, nor changed.
+#
+# Note: This will pass any form of authentication but
+# only Basic auth will work through a proxy unless the
+# connection-auth options are also used.
+#
+# login=PASS Send login details received from client to this peer.
+# Authentication is not required by this option.
+# If there are no client-provided authentication headers
+# to pass on, but username and password are available
+# from either proxy login or an external ACL user= and
+# password= result tags they may be sent instead.
+#
+# Note: To combine this with proxy_auth both proxies must
+# share the same user database as HTTP only allows for
+# a single login (one for proxy, one for origin server).
+# Also be warned this will expose your users proxy
+# password to the peer. USE WITH CAUTION
+#
+# login=*:password
+# Send the username to the upstream cache, but with a
+# fixed password. This is meant to be used when the peer
+# is in another administrative domain, but it is still
+# needed to identify each user.
+# The star can optionally be followed by some extra
+# information which is added to the username. This can
+# be used to identify this proxy to the peer, similar to
+# the login=username:password option above.
+#
+# connection-auth=on|off
+# Tell Squid that this peer does or not support Microsoft
+# connection oriented authentication, and any such
+# challenges received from there should be ignored.
+# Default is auto to automatically determine the status
+# of the peer.
+#
+#
+# ==== SSL / HTTPS / TLS OPTIONS ====
+#
+# ssl Encrypt connections to this peer with SSL/TLS.
+#
+# sslcert=/path/to/ssl/certificate
+# A client SSL certificate to use when connecting to

+#
+#
+# ==== GENERAL OPTIONS ====
+#
+# connect-timeout=N
+# A peer-specific connect timeout.
+# Also see the peer_connect_timeout directive.
+#
+# connect-fail-limit=N
+# How many times connecting to a peer must fail before
+# it is marked as down. Default is 10.
+#
+# allow-miss Disable Squid's use of only-if-cached when forwarding
+# requests to siblings. This is primarily useful when
+# icp_hit_stale is used by the sibling. To extensive use
+# of this option may result in forwarding loops, and you
+# should avoid having two-way peerings with this option.
+# For example to deny peer usage on requests from peer
+# by denying cache_peer_access if the source is a peer.
+#
+# max-conn=N Limit the amount of connections Squid may open to this
+# peer. see also
+#
+# name=xxx Unique name for the peer.
+# Required if you have multiple peers on the same host
+# but different ports.
+# This name can be used in cache_peer_access and similar
+# directives to dentify the peer.
+# Can be used by outgoing access controls through the
+# peername ACL type.
+#
+# no-tproxy Do not use the client-spoof TPROXY support when forwarding
+# requests to this peer. Use normal address selection instead.
+#
+# proxy-only objects fetched from the peer will not be stored locally.
+#
+#Default:
+# none
+
+# TAG: cache_peer_domain
+# Use to limit the domains for which a neighbor cache will be
+# queried. Usage:
+#
+# cache_peer_domain cache-host domain [domain ...]
+# cache_peer_domain cache-host !domain
+#
+# For example, specifying
+#
+# cache_peer_domain parent.foo.net .edu
+#
+# has the effect such that UDP query packets are sent to
+# 'bigserver' only when the requested object exists on a
+# server in the .edu domain. Prefixing the domainname
+# with '!' means the cache will be queried for objects
+# NOT in that domain.
+#
+# NOTE: * Any number of domains may be given for a cache-host,
+# either on the same or separate lines.
+# * When multiple domains are given for a particular
+# cache-host, the first matched domain is applied.
+# * Cache hosts with no domain restrictions are queried
+# for all requests.
+# * There are no defaults.
+# * There is also a 'cache_peer_access' tag in the ACL
+# section.
+#Default:
+# none
+
+# TAG: cache_peer_access
+# Similar to 'cache_peer_domain' but provides more flexibility by
+# using ACL elements.
+#
+# cache_peer_access cache-host allow|deny [!]aclname ...
+#
+# The syntax is identical to 'http_access' and the other lists of
+# ACL elements. See the comments for 'http_access' below, or
+# the Squid FAQ (http://wiki.squid-cache.org/SquidFaq/SquidAcl).
+#Default:
+# none
+
+# TAG: neighbor_type_domain
+# usage: neighbor_type_domain neighbor parent|sibling domain domain ...
+#
+# Modifying the neighbor type for specific domains is now
+# possible. You can treat some domains differently than the the
+# default neighbor type specified on the 'cache_peer' line.
+# Normally it should only be necessary to list domains which
+# should be treated differently because the default neighbor type
+# applies for hostnames which do not match domains listed here.
+#
+#EXAMPLE:
+# cache_peer cache.foo.org parent 3128 3130
+# neighbor_type_domain cache.foo.org sibling .com .net
+# neighbor_type_domain cache.foo.org sibling .au .de
+#Default:
+# none
+
+# TAG: dead_peer_timeout (seconds)
+# This controls how long Squid waits to declare a peer cache
+# as "dead." If there are no ICP replies received in this
+# amount of time, Squid will declare the peer dead and not
+# expect to receive any further ICP replies. However, it
+# continues to send ICP queries, and will mark the peer as
+# alive upon receipt of the first subsequent ICP reply.
+#
+# This timeout also affects when Squid expects to receive ICP
+# replies from peers. If more than 'dead_peer' seconds have
+# passed since the last ICP reply was received, Squid will not
+# expect to receive an ICP reply on the next query. Thus, if
+# your time between requests is greater than this timeout, you
+# will see a lot of requests sent DIRECT to origin servers
+# instead of to your parents.
+#Default:
+# dead_peer_timeout 10 seconds
+
+# TAG: forward_max_tries
+# Controls how many different forward paths Squid will try
+# before giving up. See also forward_timeout.
+#Default:
+# forward_max_tries 10
+
+# TAG: hierarchy_stoplist
+# A list of words which, if found in a URL, cause the object to
+# be handled directly by this cache. In other words, use this
+# to not query neighbor caches for certain objects. You may
+# list this option multiple times.
+#
+# Example:
+# hierarchy_stoplist cgi-bin ?
+#
+# Note: never_direct overrides this option.
+#Default:
+# none
+
+# MEMORY CACHE OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: cache_mem (bytes)
+# NOTE: THIS PARAMETER DOES NOT SPECIFY THE MAXIMUM PROCESS SIZE.
+# IT ONLY PLACES A LIMIT ON HOW MUCH ADDITIONAL MEMORY SQUID WILL
+# USE AS A MEMORY CACHE OF OBJECTS. SQUID USES MEMORY FOR OTHER
+# THINGS AS WELL. SEE THE SQUID FAQ SECTION 8 FOR DETAILS.
+#
+# 'cache_mem' specifies the ideal amount of memory to be used
+# for:
+# * In-Transit objects
+# * Hot Objects
+# * Negative-Cached objects
+#
+# Data for these objects are stored in 4 KB blocks. This
+# parameter specifies the ideal upper limit on the total size of
+# 4 KB blocks allocated. In-Transit objects take the highest
+# priority.
+#
+# In-transit objects have priority over the others. When
+# additional space is needed for incoming data, negative-cached
+# and hot objects will be released. In other words, the
+# negative-cached and hot objects will fill up any unused space
+# not needed for in-transit objects.
+#
+# If circumstances require, this limit will be exceeded.
+# Specifically, if your incoming request rate requires more than
+# 'cache_mem' of memory to hold in-transit objects, Squid will
+# exceed this limit to satisfy the new requests. When the load
+# decreases, blocks will be freed until the high-water mark is
+# reached. Thereafter, blocks will be used to store hot
+# objects.
+#Default:
+# cache_mem 256 MB
+
+# TAG: maximum_object_size_in_memory (bytes)
+# Objects greater than this size will not be attempted to kept in
+# the memory cache. This should be set high enough to keep objects
+# accessed frequently in memory to improve performance whilst low
+# enough to keep larger objects from hoarding cache_mem.
+#Default:
+# maximum_object_size_in_memory 512 KB
+
+# TAG: memory_replacement_policy
+# The memory replacement policy parameter determines which
+# objects are purged from memory when memory space is needed.

+
+# DISK CACHE OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: cache_replacement_policy
+# The cache replacement policy parameter determines which
+# objects are evicted (replaced) when disk space is needed.
+#
+# lru : Squid's original list based LRU policy
+# heap GDSF : Greedy-Dual Size Frequency
+# heap LFUDA: Least Frequently Used with Dynamic Aging
+# heap LRU : LRU policy implemented using a heap
+#
+# Applies to any cache_dir lines listed below this.
+#
+# The LRU policies keeps recently referenced objects.
+#
+# The heap GDSF policy optimizes object hit rate by keeping smaller
+# popular objects in cache so it has a better chance of getting a
+# hit. It achieves a lower byte hit rate than LFUDA though since
+# it evicts larger (possibly popular) objects.
+#
+# The heap LFUDA policy keeps popular objects in cache regardless of
+# their size and thus optimizes byte hit rate at the expense of
+# hit rate since one large, popular object will prevent many
+# smaller, slightly less popular objects from being cached.
+#
+# Both policies utilize a dynamic aging mechanism that prevents
+# cache pollution that can otherwise occur with frequency-based
+# replacement policies.
+#
+# NOTE: if using the LFUDA replacement policy you should increase
+# the value of maximum_object_size above its default of 4096 KB to
+# to maximize the potential byte hit rate improvement of LFUDA.

+# Usage:
+#
+# cache_dir Type Directory-Name Fs-specific-data [options]
+#
+# You can specify multiple cache_dir lines to spread the

+#
+# Type specifies the kind of storage system to use. Only "ufs"
+# is built by default. To enable any of the other storage systems
+# see the --enable-storeio configure option.
+#
+# 'Directory' is a top-level directory where cache swap
+# files will be stored. If you want to use an entire disk
+# for caching, this can be the mount-point directory.
+# The directory must exist and be writable by the Squid
+# process. Squid will NOT create this directory for you.
+#
+# The ufs store type:
+#
+# "ufs" is the old well-known Squid storage format that has always
+# been there.
+#
+# cache_dir ufs Directory-Name Mbytes L1 L2 [options]
+#
+# 'Mbytes' is the amount of disk space (MB) to use under this
+# directory. The default is 100 MB. Change this to suit your
+# configuration. Do NOT put the size of your disk drive here.
+# Instead, if you want Squid to use the entire disk drive,
+# subtract 20% and use that value.
+#
+# 'L1' is the number of first-level subdirectories which
+# will be created under the 'Directory'. The default is 16.
+#
+# 'L2' is the number of second-level subdirectories which
+# will be created under each first-level directory. The default
+# is 256.
+#
+# The aufs store type:
+#
+# "aufs" uses the same storage format as "ufs", utilizing
+# POSIX-threads to avoid blocking the main Squid process on
+# disk-I/O. This was formerly known in Squid as async-io.
+#
+# cache_dir aufs Directory-Name Mbytes L1 L2 [options]
+#
+# see argument descriptions under ufs above

+# separate process to avoid blocking the main Squid process on
+# disk-I/O.
+#
+# cache_dir diskd Directory-Name Mbytes L1 L2 [options] [Q1=n] [Q2=n]
+#
+# see argument descriptions under ufs above
+#
+# Q1 specifies the number of unacknowledged I/O requests when Squid
+# stops opening new files. If this many messages are in the queues,
+# Squid won't open new files. Default is 64
+#
+# Q2 specifies the number of unacknowledged messages when Squid
+# starts blocking. If this many messages are in the queues,
+# Squid blocks until it receives some replies. Default is 72
+#
+# When Q1 < Q2 (the default), the cache directory is optimized
+# for lower response time at the expense of a decrease in hit

+# higher hit ratio at the expense of an increase in response
+# time.
+#
+# The coss store type:
+#
+# NP: COSS filesystem in Squid-3 has been deemed too unstable for
+# production use and has thus been removed from this release.
+# We hope that it can be made usable again soon.
+#
+# block-size=n defines the "block size" for COSS cache_dir's.
+# Squid uses file numbers as block numbers. Since file numbers
+# are limited to 24 bits, the block size determines the maximum
+# size of the COSS partition. The default is 512 bytes, which
+# leads to a maximum cache_dir size of 512<<24, or 8 GB. Note
+# you should not change the coss block size after Squid
+# has written some objects to the cache_dir.
+#
+# The coss file store has changed from 2.5. Now it uses a file
+# called 'stripe' in the directory names in the config - and
+# this will be created by squid -z.
+#
+# Common options:
+#
+# no-store, no new objects should be stored to this cache_dir
+#
+# max-size=n, refers to the max object size in bytes this cache_dir
+# supports. It is used to select the cache_dir to store the object.
+# Note: To make optimal use of the max-size limits you should order
+# the cache_dir lines with the smallest max-size value first and the
+# ones with no max-size specification last.
+#
+# Note for coss, max-size must be less than COSS_MEMBUF_SZ,
+# which can be changed with the --with-coss-membuf-size=N configure
+# option.

+# TAG: cache_swap_state
+# Location for the cache "swap.state" file. This index file holds
+# the metadata of objects saved on disk. It is used to rebuild
+# the cache during startup. Normally this file resides in each
+# 'cache_dir' directory, but you may specify an alternate
+# pathname here. Note you must give a full filename, not just
+# a directory. Since this is the index for the whole object
+# list you CANNOT periodically rotate it!
+#
+# If %s can be used in the file name it will be replaced with a
+# a representation of the cache_dir name where each / is replaced
+# with '.'. This is needed to allow adding/removing cache_dir

+# Microsoft Internet Explorer up until version 5.5 Service

+# (~10% in my experience), but allows users to actually get
+# fresh content when they want it. Note because Squid
+# cannot tell if the user is using 5.5 or 5.5SP1, the behavior
+# of 5.5 is unchanged from old versions of Squid (i.e. a
+# forced refresh is impossible). Newer versions of IE will,
+# hopefully, continue to have the new behavior and will be

+# TAG: delay_parameters
+# This defines the parameters for a delay pool. Each delay pool has
+# a number of "buckets" associated with it, as explained in the
+# description of delay_class.
+#
+# For a class 1 delay pool, the syntax is:
+# delay_pools pool 1
+# delay_parameters pool aggregate
+#
+# For a class 2 delay pool:
+# delay_pools pool 2
+# delay_parameters pool aggregate individual
+#
+# For a class 3 delay pool:
+# delay_pools pool 3
+# delay_parameters pool aggregate network individual
+#
+# For a class 4 delay pool:
+# delay_pools pool 4
+# delay_parameters pool aggregate network individual user
+#
+# For a class 5 delay pool:
+# delay_pools pool 5
+# delay_parameters pool tagrate
+#
+# The option variables are:
+#
+# pool a pool number - ie, a number between 1 and the
+# number specified in delay_pools as used in
+# delay_class lines.
+#
+# aggregate the speed limit parameters for the aggregate bucket
+# (class 1, 2, 3).
+#
+# individual the speed limit parameters for the individual
+# buckets (class 2, 3).
+#
+# network the speed limit parameters for the network buckets
+# (class 3).
+#
+# user the speed limit parameters for the user buckets
+# (class 4).
+#
+# tagrate the speed limit parameters for the tag buckets
+# (class 5).
+#
+# A pair of delay parameters is written restore/maximum, where restore is
+# the number of bytes (not bits - modem and network speeds are usually
+# quoted in bits) per second placed into the bucket, and maximum is the
+# maximum number of bytes which can be in the bucket at any time.
+#
+# There must be one delay_parameters line for each delay pool.
+#
+#
+# For example, if delay pool number 1 is a class 2 delay pool as in the
+# above example, and is being used to strictly limit each host to 64Kbit/sec
+# (plus overheads), with no overall limit, the line is:
+#
+# delay_parameters 1 -1/-1 8000/8000
+#
+# Note that 8 x 8000 KByte/sec -> 64Kbit/sec.
+#
+# Note that the figure -1 is used to represent "unlimited".
+#
+#
+# And, if delay pool number 2 is a class 3 delay pool as in the above
+# example, and you want to limit it to a total of 256Kbit/sec (strict limit)
+# with each 8-bit network permitted 64Kbit/sec (strict limit) and each
+# individual host permitted 4800bit/sec with a bucket maximum size of 64Kbits
+# to permit a decent web page to be downloaded at a decent speed
+# (if the network is not being limited due to overuse) but slow down
+# large downloads more significantly:
+#
+# delay_parameters 2 32000/32000 8000/8000 600/8000
+#
+# Note that 8 x 32000 KByte/sec -> 256Kbit/sec.
+# 8 x 8000 KByte/sec -> 64Kbit/sec.
+# 8 x 600 Byte/sec -> 4800bit/sec.
+#
+#
+# Finally, for a class 4 delay pool as in the example - each user will
+# be limited to 128Kbits/sec no matter how many workstations they are logged into.:
+#
+# delay_parameters 4 32000/32000 8000/8000 600/64000 16000/16000
+#Default:
+# none
+
+# TAG: delay_initial_bucket_level (percent, 0-100)
+# The initial bucket percentage is used to determine how much is put
+# in each bucket when squid starts, is reconfigured, or first notices
+# a host accessing it (in class 2 and class 3, individual hosts and
+# networks only have buckets associated with them once they have been
+# "seen" by squid).

+
+# TAG: wccp2_service
+# WCCP2 allows for multiple traffic services. There are two

+
+# TAG: deny_info
+# Usage: deny_info err_page_name acl
+# or deny_info http://... acl
+# or deny_info TCP_RESET acl
+#
+# This can be used to return a ERR_ page for requests which
+# do not pass the 'http_access' rules. Squid remembers the last
+# acl it evaluated in http_access, and if a 'deny_info' line exists
+# for that ACL Squid returns a corresponding error page.
+#
+# The acl is typically the last acl on the http_access deny line which
+# denied access. The exceptions to this rule are:
+# - When Squid needs to request authentication credentials. It's then
+# the first authentication related acl encountered
+# - When none of the http_access lines matches. It's then the last
+# acl processed on the last http_access line.
+#
+# NP: If providing your own custom error pages with error_directory
+# you may also specify them by your custom file name:
+# Example: deny_info ERR_CUSTOM_ACCESS_DENIED bad_guys
+#
+# Alternatively you can specify an error URL. The browsers will
+# get redirected (302 or 307) to the specified URL. %s in the redirection
+# URL will be replaced by the requested URL.

+# Alternatively you can tell Squid to reset the TCP connection
+# by specifying TCP_RESET.

+# OPTIONS INFLUENCING REQUEST FORWARDING
+# -----------------------------------------------------------------------------
+
+# TAG: nonhierarchical_direct
+# By default, Squid will send any non-hierarchical requests
+# (matching hierarchy_stoplist or not cacheable request type) direct
+# to origin servers.
+#
+# If you set this to off, Squid will prefer to send these
+# requests to parents.
+#
+# Note that in most configurations, by turning this off you will only
+# add latency to these request without any improvement in global hit
+# ratio.
+#
+# If you are inside an firewall see never_direct instead of
+# this directive.
+#Default:
+# nonhierarchical_direct on
+
+# TAG: prefer_direct
+# Normally Squid tries to use parents for most requests. If you for some
+# reason like it to first try going direct and only use a parent if
+# going direct fails set this to on.
+#
+# By combining nonhierarchical_direct off and prefer_direct on you
+# can set up Squid to use a parent as a backup path if going direct
+# fails.
+#
+# Note: If you want Squid to use parents for all requests see
+# the never_direct directive. prefer_direct only modifies how Squid
+# acts on cacheable requests.
+#Default:
+# prefer_direct off
+
+# TAG: always_direct
+# Usage: always_direct allow|deny [!]aclname ...
+#
+# Here you can use ACL elements to specify requests which should
+# ALWAYS be forwarded by Squid to the origin servers without using
+# any peers. For example, to always directly forward requests for
+# local servers ignoring any parents or siblings you may have use
+# something like:
+#
+# acl local-servers dstdomain my.domain.net
+# always_direct allow local-servers
+#
+# To always forward FTP requests directly, use
+#
+# acl FTP proto FTP
+# always_direct allow FTP
+#
+# NOTE: There is a similar, but opposite option named
+# 'never_direct'. You need to be aware that "always_direct deny
+# foo" is NOT the same thing as "never_direct allow foo". You
+# may need to use a deny rule to exclude a more-specific case of
+# some other rule. Example:
+#
+# acl local-external dstdomain external.foo.net
+# acl local-servers dstdomain .foo.net
+# always_direct deny local-external
+# always_direct allow local-servers
+#
+# NOTE: If your goal is to make the client forward the request
+# directly to the origin server bypassing Squid then this needs
+# to be done in the client configuration. Squid configuration
+# can only tell Squid how Squid should fetch the object.
+#
+# NOTE: This directive is not related to caching. The replies
+# is cached as usual even if you use always_direct. To not cache
+# the replies see the 'cache' directive.
+#
+# This clause supports both fast and slow acl types.
+# See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
+#Default:
+# none
+
+# TAG: never_direct
+# Usage: never_direct allow|deny [!]aclname ...
+#
+# never_direct is the opposite of always_direct. Please read
+# the description for always_direct if you have not already.
+#
+# With 'never_direct' you can use ACL elements to specify
+# requests which should NEVER be forwarded directly to origin
+# servers. For example, to force the use of a proxy for all
+# requests, except those in your local domain use something like:
+#
+# acl local-servers dstdomain .foo.net
+# never_direct deny local-servers
+# never_direct allow all
+#
+# or if Squid is inside a firewall and there are local intranet
+# servers inside the firewall use something like:
+#
+# acl local-intranet dstdomain .foo.net
+# acl local-external dstdomain external.foo.net
+# always_direct deny local-external
+# always_direct allow local-intranet
+# never_direct allow all

+#
+# Routing is not allowed by default: the ICAP X-Next-Services

+#
+# ipv6=on|off
+# Only has effect on split-stack systems. The default on those systems

+
+# TAG: dns_timeout
+# DNS Query timeout. If no response is received to a DNS query
+# within this time all DNS servers for the queried domain

+#Default:
+# dns_timeout 2 minutes
+
+# TAG: dns_defnames on|off
+# Normally the RES_DEFNAMES resolver option is disabled
+# (see res_init(3)). This prevents caches in a hierarchy
+# from interpreting single-component hostnames locally. To allow
+# Squid to handle single-component names, enable this option.
+#Default:
+# dns_defnames off
+
+# TAG: dns_nameservers
+# Use this if you want to specify a list of DNS name servers
+# (IP addresses) to use instead of those given in your
+# /etc/resolv.conf file.
+# On Windows platforms, if no value is specified here or in
+# the /etc/resolv.conf file, the list of DNS name servers are
+# taken from the Windows registry, both static and dynamic DHCP
+# configurations are supported.
+#
+# Example: dns_nameservers 10.0.0.1 192.172.0.4
+#Default:
+# none
+
+# TAG: hosts_file
+# Location of the host-local IP name-address associations
+# database. Most Operating Systems have such a file on different
+# default locations:
+# - Un*X & Linux: /etc/hosts

+# character are comments.
+#
+# The file is checked at startup and upon configuration.
+# If set to 'none', it won't be checked.
+# If append_domain is used, that domain will be added to
+# domain-local (i.e. not containing any dot character) host
+# definitions.
+#Default:
+# hosts_file /etc/hosts
+
+# TAG: append_domain
+# Appends local domain name to hostnames without any dots in

+#
+# Be warned there are now Internet names with no dots in

+# cause some Internet sites to become unavailable.
+#
+#Example:
+# append_domain .yourdomain.com
+#Default:
+# none
+
+# TAG: ignore_unknown_nameservers
+# By default Squid checks that DNS responses are received
+# from the same IP addresses they are sent to. If they
+# don't match, Squid ignores the response and writes a warning
+# message to cache.log. You can allow responses from unknown
+# nameservers by setting this option to 'off'.
+#Default:
+# ignore_unknown_nameservers on
+
+# TAG: dns_v4_fallback
+# Standard practice with DNS is to lookup either A or AAAA records
+# and use the results if it succeeds. Only looking up the other if
+# the first attempt fails or otherwise produces no results.
+#
+# That policy however will cause squid to produce error pages for some
+# servers that advertise AAAA but are unreachable over IPv6.
+#
+# If this is ON squid will always lookup both AAAA and A, using both.
+# If this is OFF squid will lookup AAAA and only try A if none found.
+#
+# WARNING: There are some possibly unwanted side-effects with this on:
+# *) Doubles the load placed by squid on the DNS network.
+# *) May negatively impact connection delay times.
+#Default:
+# dns_v4_fallback on
+
+# TAG: dns_v4_first
+# With the IPv6 Internet being as fast or faster than IPv4 Internet
+# for most networks Squid prefers to contact websites over IPv6.
+#
+# This option reverses the order of preference to make Squid contact
+# dual-stack websites over IPv4 first. Squid will still perform both
+# IPv6 and IPv4 DNS lookups before connecting.
+#
+# WARNING:
+# This option will restrict the situations under which IPv6
+# connectivity is used (and tested), potentially hiding network
+# problem swhich would otherwise be detected and warned about.

+
+# TAG: memory_pools on|off
+# If set, Squid will keep pools of allocated (but unused) memory
+# available for future use. If memory is a premium on your
+# system and you believe your malloc library outperforms Squid
+# routines, disable this.
+#Default:
+# memory_pools on
+
+# TAG: memory_pools_limit (bytes)
+# Used only with memory_pools on:
+# memory_pools_limit 50 MB
+#
+# If set to a non-zero value, Squid will keep at most the specified
+# limit of allocated (but unused) memory in memory pools. All free()
+# requests that exceed this limit will be handled by your malloc
+# library. Squid does not pre-allocate any memory, just safe-keeps
+# objects that otherwise would be free()d. Thus, it is safe to set
+# memory_pools_limit to a reasonably high value even if your
+# configuration will use less memory.
+#
+# If set to none, Squid will keep all memory it can. That is, there
+# will be no limit on the total amount of memory used for safe-keeping.
+#
+# To disable memory allocation optimization, do not set
+# memory_pools_limit to 0 or none. Set memory_pools to "off" instead.
+#
+# An overhead for maintaining memory pools is not taken into account
+# when the limit is checked. This overhead is close to four bytes per
+# object kept. However, pools may actually _save_ memory because of
+# reduced memory thrashing in your malloc library.
+#Default:
+# memory_pools_limit 5 MB
+
+# TAG: forwarded_for on|off|transparent|truncate|delete
+# If set to "on", Squid will append your client's IP address
+# in the HTTP requests it forwards. By default it looks like:
+#
+# X-Forwarded-For: 192.1.2.3
+#
+# If set to "off", it will appear as
+#
+# X-Forwarded-For: unknown
+#
+# If set to "transparent", Squid will not alter the
+# X-Forwarded-For header in any way.
+#
+# If set to "delete", Squid will delete the entire
+# X-Forwarded-For header.
+#
+# If set to "truncate", Squid will remove all existing
+# X-Forwarded-For entries, and place itself as the sole entry.
+#Default:
+# forwarded_for on
+
+# TAG: cachemgr_passwd
+# Specify passwords for cachemgr operations.
+#
+# Usage: cachemgr_passwd password action action ...
+#
+# Some valid actions are (see cache manager menu for a full list):

+
+# TAG: client_db on|off
+# If you want to disable collecting per-client statistics,
+# turn off client_db here.
+#Default:
+# client_db on
+
+# TAG: refresh_all_ims on|off
+# When you enable this option, squid will always check
+# the origin server for an update when a client sends an
+# If-Modified-Since request. Many browsers use IMS
+# requests when the user requests a reload, and this
+# ensures those clients receive the latest version.
+#
+# By default (off), squid may return a Not Modified response
+# based on the age of the cached version.
+#Default:
+# refresh_all_ims off
+
+# TAG: reload_into_ims on|off
+# When you enable this option, client no-cache or ``reload''
+# requests will be changed to If-Modified-Since requests.
+# Doing this VIOLATES the HTTP standard. Enabling this
+# feature could make you liable for problems which it
+# causes.
+#
+# see also refresh_pattern for a more selective approach.
+#Default:
+# reload_into_ims off
+
+# TAG: maximum_single_addr_tries
+# This sets the maximum number of connection attempts for a
+# host that only has one address (for multiple-address hosts,
+# each address is tried once).
+#
+# The default value is one attempt, the (not recommended)
+# maximum is 255 tries. A warning message will be generated
+# if it is set to a value greater than ten.
+#
+# Note: This is in addition to the request re-forwarding which
+# takes place if Squid fails to get a satisfying response.
+#Default:
+# maximum_single_addr_tries 1
+
+# TAG: retry_on_error
+# If set to ON Squid will automatically retry requests when
+# receiving an error response with status 403 (Forbidden),
+# 500 (Internal Error), 501 or 503 (Service not available).
+# Status 502 and 504 (Gateway errors) are always retried.
+#
+# This is mainly useful if you are in a complex cache hierarchy to
+# work around access control errors.
+#
+# NOTE: This retry will attempt to find another working destination.
+# Which is different from the server which just failed.
+#Default:
+# retry_on_error off
+
+# TAG: as_whois_server
+# WHOIS server to query for AS numbers. NOTE: AS numbers are
+# queried only when Squid starts up, not for every request.
+#Default:
+# as_whois_server whois.ra.net
+
+# TAG: offline_mode
+# Enable this option and Squid will never try to validate cached
+# objects.
+#Default:
+# offline_mode off
+
+# TAG: uri_whitespace
+# What to do with requests that have whitespace characters in the
+# URI. Options:
+#
+# strip: The whitespace characters are stripped out of the URL.
+# This is the behavior recommended by RFC2396.
+# deny: The request is denied. The user receives an "Invalid
+# Request" message.
+# allow: The request is allowed and the URI is not changed. The
+# whitespace characters remain in the URI. Note the
+# whitespace is passed to redirector processes if they
+# are in use.
+# encode: The request is allowed and the whitespace characters are
+# encoded according to RFC1738. This could be considered
+# a violation of the HTTP/1.1
+# RFC because proxies are not allowed to rewrite URI's.
+# chop: The request is allowed and the URI is chopped at the
+# first whitespace. This might also be considered a
+# violation.
+#Default:
+# uri_whitespace strip
+
+# TAG: chroot
+# Specifies a directory where Squid should do a chroot() while
+# initializing. This also causes Squid to fully drop root
+# privileges after initializing. This means, for example, if you
+# use a HTTP port less than 1024 and try to reconfigure, you may
+# get an error saying that Squid can not open the port.
+#Default:
+# none
+
+# TAG: balance_on_multiple_ip
+# Modern IP resolvers in squid sort lookup results by preferred access.
+# By default squid will use these IP in order and only rotates to
+# the next listed when the most preffered fails.
+#
+# Some load balancing servers based on round robin DNS have been
+# found not to preserve user session state across requests
+# to different IP addresses.
+#
+# Enabling this directive Squid rotates IP's per request.
+#Default:
+# balance_on_multiple_ip off
+
+# TAG: pipeline_prefetch
+# To boost the performance of pipelined requests to closer
+# match that of a non-proxied environment Squid can try to fetch
+# up to two requests in parallel from a pipeline.
+#
+# Defaults to off for bandwidth management and access logging
+# reasons.
+#
+# WARNING: pipelining breaks NTLM and Negotiate/Kerberos authentication.
+#Default:
+# pipeline_prefetch off
+
+# TAG: high_response_time_warning (msec)
+# If the one-minute median response time exceeds this value,
+# Squid prints a WARNING with debug level 0 to get the
+# administrators attention. The value is in milliseconds.
+#Default:
+# high_response_time_warning 0
+
+# TAG: high_page_fault_warning
+# If the one-minute average page fault rate exceeds this
+# value, Squid prints a WARNING with debug level 0 to get
+# the administrators attention. The value is in page faults
+# per second.
+#Default:
+# high_page_fault_warning 0
+
+# TAG: high_memory_warning
+# If the memory usage (as determined by mallinfo) exceeds
+# this amount, Squid prints a WARNING with debug level 0 to get
+# the administrators attention.
+#Default:
+# high_memory_warning 0 KB
+
+# TAG: sleep_after_fork (microseconds)
+# When this is set to a non-zero value, the main Squid process
+# sleeps the specified number of microseconds after a fork()
+# system call. This sleep may help the situation where your
+# system reports fork() failures due to lack of (virtual)
+# memory. Note, however, if you have a lot of child
+# processes, these sleep delays will add up and your
+# Squid will not service requests for some amount of time
+# until all the child processes have been started.
+# On Windows value less then 1000 (1 milliseconds) are
+# rounded to 1000.
+#Default:
+# sleep_after_fork 0
+
+# TAG: windows_ipaddrchangemonitor on|off
+# On Windows Squid by default will monitor IP address changes and will
+# reconfigure itself after any detected event. This is very useful for
+# proxies connected to internet with dial-up interfaces.
+# In some cases (a Proxy server acting as VPN gateway is one) it could be
+# desiderable to disable this behaviour setting this to 'off'.
+# Note: after changing this, Squid service must be restarted.
+#Default:
+# windows_ipaddrchangemonitor on
+
+# TAG: max_filedescriptors
+# The maximum number of filedescriptors supported.
+#
+# The default "0" means Squid inherits the current ulimit setting.
+#
+# Note: Changing this requires a restart of Squid. Also
+# not all comm loops supports large values.
+#Default:
+# max_filedescriptors 0

+# WELCOME TO SQUID 3.1.20
+# ----------------------------
+#
+# This is the documentation for the Squid configuration file.
+# This documentation can also be found online at:
+# http://www.squid-cache.org/Doc/config/
+#
+# You may wish to look at the Squid home page and wiki for the
+# FAQ and other documentation:
+# http://www.squid-cache.org/
+# http://wiki.squid-cache.org/SquidFaq
+# http://wiki.squid-cache.org/ConfigExamples
+#
+# This documentation shows what the defaults for various directives
+# happen to be. If you don't need to change the default, you should
+# leave the line out of your squid.conf in most cases.
+#
+# In some cases "none" refers to no default setting at all,
+# while in other cases it refers to the value of the option
+# - the comments for that keyword indicate if this is the case.
+#
+
+# Configuration options can be included using the "include" directive.
+# Include takes a list of files to include. Quoting and wildcards are
+# supported.
+#
+# For example,
+#
+# include /path/to/included/file/squid.acl.config
+#
+# Includes can be nested up to a hard-coded depth of 16 levels.
+# This arbitrary restriction is to prevent recursive include references
+# from causing Squid entering an infinite loop whilst trying to load
+# configuration files.

+
+# OPTIONS FOR AUTHENTICATION
+# -----------------------------------------------------------------------------
+
+# TAG: auth_param
+# This is used to define parameters for the various authentication
+# schemes supported by Squid.
+#
+# format: auth_param scheme parameter [setting]
+#
+# The order in which authentication schemes are presented to the client is
+# dependent on the order the scheme first appears in config file. IE
+# has a bug (it's not RFC 2617 compliant) in that it will use the basic
+# scheme if basic is the first entry presented, even if more secure
+# schemes are presented. For now use the order in the recommended
+# settings section below. If other browsers have difficulties (don't
+# recognize the schemes offered even if you are using basic) either
+# put basic first, or disable the other schemes (by commenting out their
+# program entry).
+#
+# Once an authentication scheme is fully configured, it can only be
+# shutdown by shutting squid down and restarting. Changes can be made on
+# the fly and activated with a reconfigure. I.E. You can change to a
+# different helper, but not unconfigure the helper completely.
+#
+# Please note that while this directive defines how Squid processes
+# authentication it does not automatically activate authentication.
+# To use authentication you must in addition make use of ACLs based
+# on login name in http_access (proxy_auth, proxy_auth_regex or
+# external with %LOGIN used in the format tag). The browser will be
+# challenged for authentication on the first such acl encountered
+# in http_access processing and will also be re-challenged for new
+# login credentials if the request is being denied by a proxy_auth
+# type acl.
+#
+# WARNING: authentication can't be used in a transparently intercepting
+# proxy as the client then thinks it is talking to an origin server and
+# not the proxy. This is a limitation of bending the TCP/IP protocol to
+# transparently intercepting port 80, not a limitation in Squid.
+# Ports flagged 'transparent', 'intercept', or 'tproxy' have
+# authentication disabled.
+#
+# === Parameters for the basic scheme follow. ===
+#
+# "program" cmdline
+# Specify the command for the external authenticator. Such a program
+# reads a line containing "username password" and replies "OK" or
+# "ERR" in an endless loop. "ERR" responses may optionally be followed
+# by a error description available as %m in the returned error page.
+# If you use an authenticator, make sure you have 1 acl of type
+# proxy_auth.
+#
+# By default, the basic authentication scheme is not used unless a
+# program is specified.
+#
+# If you want to use the traditional NCSA proxy authentication, set
+# this line to something like
+#
+# auth_param basic program /usr/lib/squid3/ncsa_auth /usr/etc/passwd
+#
+# "utf8" on|off
+# HTTP uses iso-latin-1 as characterset, while some authentication
+# backends such as LDAP expects UTF-8. If this is set to on Squid will
+# translate the HTTP iso-latin-1 charset to UTF-8 before sending the
+# username & password to the helper.
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn. If you start too few
+# Squid will have to wait for them to process a backlog of credential
+# verifications, slowing it down. When password verifications are
+# done via a (slow) network you are likely to need lots of
+# authenticator processes.
+# auth_param basic children 5
+#
+# "concurrency" concurrency
+# The number of concurrent requests the helper can process.
+# The default of 0 is used for helpers who only supports
+# one request at a time. Setting this changes the protocol used to
+# include a channel number first on the request/response line, allowing
+# multiple requests to be sent to the same helper in parallell without
+# wating for the response.
+# Must not be set unless it's known the helper supports this.
+# auth_param basic concurrency 0
+#
+# "realm" realmstring
+# Specifies the realm name which is to be reported to the
+# client for the basic proxy authentication scheme (part of
+# the text the user will see when prompted their username and
+# password). There is no default.
+# auth_param basic realm Squid proxy-caching web server
+#
+# "credentialsttl" timetolive
+# Specifies how long squid assumes an externally validated
+# username:password pair is valid for - in other words how
+# often the helper program is called for that user. Set this
+# low to force revalidation with short lived passwords. Note
+# setting this high does not impact your susceptibility
+# to replay attacks unless you are using an one-time password
+# system (such as SecureID). If you are using such a system,
+# you will be vulnerable to replay attacks unless you also
+# use the max_user_ip ACL in an http_access rule.
+#
+# "casesensitive" on|off
+# Specifies if usernames are case sensitive. Most user databases are
+# case insensitive allowing the same username to be spelled using both
+# lower and upper case letters, but some are case sensitive. This
+# makes a big difference for user_max_ip ACL processing and similar.
+# auth_param basic casesensitive off
+#
+# === Parameters for the digest scheme follow ===
+#
+# "program" cmdline
+# Specify the command for the external authenticator. Such
+# a program reads a line containing "username":"realm" and
+# replies with the appropriate H(A1) value hex encoded or
+# ERR if the user (or his H(A1) hash) does not exists.
+# See rfc 2616 for the definition of H(A1).
+# "ERR" responses may optionally be followed by a error description
+# available as %m in the returned error page.
+#
+# By default, the digest authentication scheme is not used unless a
+# program is specified.
+#
+# If you want to use a digest authenticator, set this line to
+# something like
+#
+# auth_param digest program /usr/lib/squid3/digest_pw_auth /usr/etc/digpass
+#
+# "utf8" on|off
+# HTTP uses iso-latin-1 as characterset, while some authentication
+# backends such as LDAP expects UTF-8. If this is set to on Squid will
+# translate the HTTP iso-latin-1 charset to UTF-8 before sending the
+# username & password to the helper.
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to
+# process a backlog of H(A1) calculations, slowing it down.
+# When the H(A1) calculations are done via a (slow) network
+# you are likely to need lots of authenticator processes.
+# auth_param digest children 5
+#
+# "realm" realmstring
+# Specifies the realm name which is to be reported to the
+# client for the digest proxy authentication scheme (part of
+# the text the user will see when prompted their username and
+# password). There is no default.
+# auth_param digest realm Squid proxy-caching web server
+#
+# "nonce_garbage_interval" timeinterval
+# Specifies the interval that nonces that have been issued
+# to client_agent's are checked for validity.
+#
+# "nonce_max_duration" timeinterval
+# Specifies the maximum length of time a given nonce will be
+# valid for.
+#
+# "nonce_max_count" number
+# Specifies the maximum number of times a given nonce can be
+# used.
+#
+# "nonce_strictness" on|off
+# Determines if squid requires strict increment-by-1 behavior
+# for nonce counts, or just incrementing (off - for use when
+# useragents generate nonce counts that occasionally miss 1
+# (ie, 1,2,4,6)). Default off.
+#
+# "check_nonce_count" on|off
+# This directive if set to off can disable the nonce count check
+# completely to work around buggy digest qop implementations in
+# certain mainstream browser versions. Default on to check the
+# nonce count to protect from authentication replay attacks.
+#
+# "post_workaround" on|off
+# This is a workaround to certain buggy browsers who sends
+# an incorrect request digest in POST requests when reusing
+# the same nonce as acquired earlier on a GET request.
+#
+# === NTLM scheme options follow ===
+#
+# "program" cmdline
+# Specify the command for the external NTLM authenticator.
+# Such a program reads exchanged NTLMSSP packets with
+# the browser via Squid until authentication is completed.
+# If you use an NTLM authenticator, make sure you have 1 acl
+# of type proxy_auth. By default, the NTLM authenticator_program
+# is not used.
+#
+# auth_param ntlm program /usr/lib/squid3/ntlm_auth
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to
+# process a backlog of credential verifications, slowing it
+# down. When credential verifications are done via a (slow)
+# network you are likely to need lots of authenticator
+# processes.
+#
+# auth_param ntlm children 5
+#
+# "keep_alive" on|off
+# Whether to keep the connection open after the initial response where
+# Squid tells the browser which schemes are supported by the proxy.
+# Some browsers are known to present many login popups or to corrupt
+# POST/PUT requests transfer if the connection is not closed.
+# The default is currently OFF to avoid this, but may change.
+#
+# auth_param ntlm keep_alive on
+#
+# === Options for configuring the NEGOTIATE auth-scheme follow ===
+#
+# "program" cmdline
+# Specify the command for the external Negotiate authenticator.
+# This protocol is used in Microsoft Active-Directory enabled setups with
+# the Microsoft Internet Explorer or Mozilla Firefox browsers.
+# Its main purpose is to exchange credentials with the Squid proxy
+# using the Kerberos mechanisms.
+# If you use a Negotiate authenticator, make sure you have at least
+# one acl of type proxy_auth active. By default, the negotiate
+# authenticator_program is not used.
+# The only supported program for this role is the ntlm_auth
+# program distributed as part of Samba, version 4 or later.
+#
+# auth_param negotiate program /usr/lib/squid3/ntlm_auth --helper-protocol=gss-spnego
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to
+# process a backlog of credential verifications, slowing it
+# down. When crendential verifications are done via a (slow)
+# network you are likely to need lots of authenticator
+# processes.
+# auth_param negotiate children 5
+#
+# "keep_alive" on|off
+# Whether to keep the connection open after the initial response where
+# Squid tells the browser which schemes are supported by the proxy.
+# Some browsers are known to present many login popups or to corrupt
+# POST/PUT requests transfer if the connection is not closed.
+# The default is currently OFF to avoid this, but may change.
+#
+# auth_param negotiate keep_alive on
+#
+#
+# Examples:
+#
+##Recommended minimum configuration per scheme:
+##auth_param negotiate program <uncomment and complete this line to activate>
+##auth_param negotiate children 5
+##auth_param negotiate keep_alive on
+##
+##auth_param ntlm program <uncomment and complete this line to activate>
+##auth_param ntlm children 5
+##auth_param ntlm keep_alive on
+##
+##auth_param digest program <uncomment and complete this line>
+##auth_param digest children 5
+##auth_param digest realm Squid proxy-caching web server
+##auth_param digest nonce_garbage_interval 5 minutes
+##auth_param digest nonce_max_duration 30 minutes
+##auth_param digest nonce_max_count 50
+##
+##auth_param basic program <uncomment and complete this line>
+##auth_param basic children 5
+##auth_param basic realm Squid proxy-caching web server
+##auth_param basic credentialsttl 2 hours
+#Default:
+# none
+
+# TAG: authenticate_cache_garbage_interval
+# The time period between garbage collection across the username cache.
+# This is a tradeoff between memory utilization (long intervals - say
+# 2 days) and CPU (short intervals - say 1 minute). Only change if you
+# have good reason to.
+#Default:
+# authenticate_cache_garbage_interval 1 hour
+
+# TAG: authenticate_ttl
+# The time a user & their credentials stay in the logged in
+# user cache since their last request. When the garbage
+# interval passes, all user credentials that have passed their
+# TTL are removed from memory.
+#Default:
+# authenticate_ttl 1 hour
+
+# TAG: authenticate_ip_ttl
+# If you use proxy authentication and the 'max_user_ip' ACL,
+# this directive controls how long Squid remembers the IP
+# addresses associated with each user. Use a small value
+# (e.g., 60 seconds) if your users might change addresses
+# quickly, as is the case with dialups. You might be safe
+# using a larger value (e.g., 2 hours) in a corporate LAN
+# environment with relatively static address assignments.
+#Default:
+# authenticate_ip_ttl 0 seconds
+
+# ACCESS CONTROLS
+# -----------------------------------------------------------------------------
+
+# TAG: external_acl_type
+# This option defines external acl classes using a helper program
+# to look up the status
+#
+# external_acl_type name [options] FORMAT.. /path/to/helper [helper arguments..]
+#
+# Options:
+#
+# ttl=n TTL in seconds for cached results (defaults to 3600
+# for 1 hour)
+# negative_ttl=n
+# TTL for cached negative lookups (default same
+# as ttl)
+# children=n Number of acl helper processes spawn to service
+# external acl lookups of this type. (default 5)
+# concurrency=n concurrency level per process. Only used with helpers
+# capable of processing more than one query at a time.
+# cache=n result cache size, 0 is unbounded (default)
+# grace=n Percentage remaining of TTL where a refresh of a

+# wait for a new reply. (default 0 for no grace period)
+# protocol=2.5 Compatibility mode for Squid-2.5 external acl helpers
+# ipv4 / ipv6 IP protocol used to communicate with this helper.
+# The default is to auto-detect IPv6 and use it when available.

+#
+# %<{Header} HTTP reply header "Header"
+# %<{Hdr:member}
+# HTTP reply header "Hdr" list member "member"

+#
+# %% The percent sign. Useful for helpers which need
+# an unchanging input format.
+#
+# In addition to the above, any string specified in the referencing
+# acl will also be included in the helper request line, after the
+# specified formats (see the "acl external" directive)
+#
+# The helper receives lines per the above format specification,
+# and returns lines starting with OK or ERR indicating the validity
+# of the request and optionally followed by additional keywords with
+# more details.
+#
+# General result syntax:
+#
+# OK/ERR keyword=value ...
+#
+# Defined keywords:
+#
+# user= The users name (login)
+# password= The users password (for login= cache_peer option)
+# message= Message describing the reason. Available as %o
+# in error pages
+# tag= Apply a tag to a request (for both ERR and OK results)
+# Only sets a tag, does not alter existing tags.
+# log= String to be logged in access.log. Available as
+# %ea in logformat specifications
+#
+# If protocol=3.0 (the default) then URL escaping is used to protect
+# each value in both requests and responses.
+#
+# If using protocol=2.5 then all values need to be enclosed in quotes
+# if they may contain whitespace, or the whitespace escaped using \.
+# And quotes or \ characters within the keyword value must be \ escaped.
+#
+# When using the concurrency= option the protocol is changed by
+# introducing a query channel tag infront of the request/response.
+# The query channel tag is a number between 0 and concurrency-1.
+#Default:
+# none
+
+# TAG: acl
+# Defining an Access List
+#
+# Every access list definition must begin with an aclname and acltype,
+# followed by either type-specific arguments or a quoted filename that
+# they are read from.
+#
+# acl aclname acltype argument ...
+# acl aclname acltype "file" ...
+#
+# When using "file", the file should contain one item per line.
+#
+# By default, regular expressions are CASE-SENSITIVE.
+# To make them case-insensitive, use the -i option. To return case-sensitive
+# use the +i option between patterns, or make a new ACL line without -i.
+#
+# Some acl types require suspending the current request in order

+#
+# acl aclname max_user_ip [-s] number
+# # This will be matched when the user attempts to log in from more

+# # If -s is specified the limit is strict, denying browsing

+#
+# Requests may pass through a chain of several other proxies

+# comma-separated list of the IP addresses in the chain, with the
+# rightmost address being the most recent.
+#
+# If a request reaches us from a source that is allowed by this
+# configuration item, then we consult the X-Forwarded-For header
+# to see where that host received the request from. If the
+# X-Forwarded-For header contains multiple addresses, we continue
+# backtracking until we reach an address for which we are not allowed
+# to follow the X-Forwarded-For header, or until we reach the first
+# address in the list. For the purpose of ACL used in the
+# follow_x_forwarded_for directive the src ACL type always matches
+# the address we are testing and srcdomain matches its rDNS.
+#
+# The end result of this process is an IP address that we will

+# IPv6 Magic:
+#
+# Squid is built with a capability of bridging the IPv4 and IPv6
+# internets.
+# tcp_outgoing_address as exampled above breaks this bridging by forcing
+# all outbound traffic through a certain IPv4 which may be on the wrong
+# side of the IPv4/IPv6 boundary.
+#
+# To operate with tcp_outgoing_address and keep the bridging benefits
+# an additional ACL needs to be used which ensures the IPv6-bound traffic
+# is never forced or permitted out the IPv4 interface.
+#
+# # IPv6 destination test along with a dummy access control to perform the required DNS
+# # This MUST be place before any ALLOW rules.
+# acl to_ipv6 dst ipv6
+# http_access deny ipv6 !all

+# WARNING:
+# 'dst ipv6' bases its selection assuming DIRECT access.
+# If peers are used the peername ACL are needed to select outgoing
+# address which can link to the peer.
+#
+# 'dst ipv6' is a slow ACL. It will only work here if 'dst' is used

+# OPTIONS WHICH AFFECT THE NEIGHBOR SELECTION ALGORITHM
+# -----------------------------------------------------------------------------
+
+# TAG: cache_peer
+# To specify other caches in a hierarchy, use the format:
+#
+# cache_peer hostname type http-port icp-port [options]
+#
+# For example,
+#
+# # proxy icp
+# # hostname type port port options
+# # -------------------- -------- ----- ----- -----------
+# cache_peer parent.foo.net parent 3128 3130 default
+# cache_peer sib1.foo.net sibling 3128 3130 proxy-only
+# cache_peer sib2.foo.net sibling 3128 3130 proxy-only
+# cache_peer example.com parent 80 0 default
+# cache_peer cdn.example.com sibling 3128 0
+#
+# type: either 'parent', 'sibling', or 'multicast'.
+#
+# proxy-port: The port number where the peer accept HTTP requests.
+# For other Squid proxies this is usually 3128
+# For web servers this is usually 80
+#
+# icp-port: Used for querying neighbor caches about objects.
+# Set to 0 if the peer does not support ICP or HTCP.
+# See ICP and HTCP options below for additional details.
+#
+#
+# ==== ICP OPTIONS ====
+#
+# You MUST also set icp_port and icp_access explicitly when using these options.
+# The defaults will prevent peer traffic using ICP.
+#
+#
+# no-query Disable ICP queries to this neighbor.
+#
+# multicast-responder
+# Indicates the named peer is a member of a multicast group.
+# ICP queries will not be sent directly to the peer, but ICP
+# replies will be accepted from it.
+#
+# closest-only Indicates that, for ICP_OP_MISS replies, we'll only forward
+# CLOSEST_PARENT_MISSes and never FIRST_PARENT_MISSes.
+#
+# background-ping
+# To only send ICP queries to this neighbor infrequently.
+# This is used to keep the neighbor round trip time updated
+# and is usually used in conjunction with weighted-round-robin.
+#
+#
+# ==== HTCP OPTIONS ====
+#
+# You MUST also set htcp_port and htcp_access explicitly when using these options.
+# The defaults will prevent peer traffic using HTCP.
+#
+#
+# htcp Send HTCP, instead of ICP, queries to the neighbor.
+# You probably also want to set the "icp-port" to 4827
+# instead of 3130.
+#
+# htcp-oldsquid Send HTCP to old Squid versions.
+#
+# htcp-no-clr Send HTCP to the neighbor but without
+# sending any CLR requests. This cannot be used with
+# htcp-only-clr.
+#
+# htcp-only-clr Send HTCP to the neighbor but ONLY CLR requests.
+# This cannot be used with htcp-no-clr.
+#
+# htcp-no-purge-clr
+# Send HTCP to the neighbor including CLRs but only when
+# they do not result from PURGE requests.
+#
+# htcp-forward-clr
+# Forward any HTCP CLR requests this proxy receives to the peer.
+#
+#
+# ==== PEER SELECTION METHODS ====
+#
+# The default peer selection method is ICP, with the first responding peer
+# being used as source. These options can be used for better load balancing.
+#
+#
+# default This is a parent cache which can be used as a "last-resort"
+# if a peer cannot be located by any of the peer-selection methods.
+# If specified more than once, only the first is used.
+#
+# round-robin Load-Balance parents which should be used in a round-robin
+# fashion in the absence of any ICP queries.
+# weight=N can be used to add bias.
+#
+# weighted-round-robin
+# Load-Balance parents which should be used in a round-robin
+# fashion with the frequency of each parent being based on the
+# round trip time. Closer parents are used more often.
+# Usually used for background-ping parents.
+# weight=N can be used to add bias.
+#
+# carp Load-Balance parents which should be used as a CARP array.
+# The requests will be distributed among the parents based on the
+# CARP load balancing hash function based on their weight.
+#
+# userhash Load-balance parents based on the client proxy_auth or ident username.
+#
+# sourcehash Load-balance parents based on the client source IP.
+#
+# multicast-siblings
+# To be used only for cache peers of type "multicast".
+# ALL members of this multicast group have "sibling"
+# relationship with it, not "parent". This is to a multicast
+# group when the requested object would be fetched only from
+# a "parent" cache, anyway. It's useful, e.g., when
+# configuring a pool of redundant Squid proxies, being
+# members of the same multicast group.
+#
+#
+# ==== PEER SELECTION OPTIONS ====
+#
+# weight=N use to affect the selection of a peer during any weighted
+# peer-selection mechanisms.
+# The weight must be an integer; default is 1,
+# larger weights are favored more.
+# This option does not affect parent selection if a peering
+# protocol is not in use.
+#
+# basetime=N Specify a base amount to be subtracted from round trip
+# times of parents.
+# It is subtracted before division by weight in calculating
+# which parent to fectch from. If the rtt is less than the
+# base time the rtt is set to a minimal value.
+#
+# ttl=N Specify a TTL to use when sending multicast ICP queries
+# to this address.
+# Only useful when sending to a multicast group.
+# Because we don't accept ICP replies from random
+# hosts, you must configure other group members as
+# peers with the 'multicast-responder' option.
+#
+# no-delay To prevent access to this neighbor from influencing the
+# delay pools.
+#
+# digest-url=URL Tell Squid to fetch the cache digest (if digests are
+# enabled) for this host from the specified URL rather
+# than the Squid default location.
+#
+#
+# ==== ACCELERATOR / REVERSE-PROXY OPTIONS ====
+#
+# originserver Causes this parent to be contacted as an origin server.
+# Meant to be used in accelerator setups when the peer
+# is a web server.
+#
+# forceddomain=name
+# Set the Host header of requests forwarded to this peer.
+# Useful in accelerator setups where the server (peer)
+# expects a certain domain name but clients may request
+# others. ie example.com or www.example.com
+#
+# no-digest Disable request of cache digests.
+#
+# no-netdb-exchange
+# Disables requesting ICMP RTT database (NetDB).
+#
+#
+# ==== AUTHENTICATION OPTIONS ====
+#
+# login=user:password
+# If this is a personal/workgroup proxy and your parent
+# requires proxy authentication.
+#
+# Note: The string can include URL escapes (i.e. %20 for
+# spaces). This also means % must be written as %%.
+#
+# login=PROXYPASS
+# Send login details received from client to this peer.
+# Authentication is not required, nor changed.
+#
+# Note: This will pass any form of authentication but
+# only Basic auth will work through a proxy unless the
+# connection-auth options are also used.
+#
+# login=PASS Send login details received from client to this peer.
+# Authentication is not required by this option.
+# If there are no client-provided authentication headers
+# to pass on, but username and password are available
+# from either proxy login or an external ACL user= and
+# password= result tags they may be sent instead.
+#
+# Note: To combine this with proxy_auth both proxies must
+# share the same user database as HTTP only allows for
+# a single login (one for proxy, one for origin server).
+# Also be warned this will expose your users proxy
+# password to the peer. USE WITH CAUTION
+#
+# login=*:password
+# Send the username to the upstream cache, but with a
+# fixed password. This is meant to be used when the peer
+# is in another administrative domain, but it is still
+# needed to identify each user.
+# The star can optionally be followed by some extra
+# information which is added to the username. This can
+# be used to identify this proxy to the peer, similar to
+# the login=username:password option above.
+#
+# connection-auth=on|off
+# Tell Squid that this peer does or not support Microsoft
+# connection oriented authentication, and any such
+# challenges received from there should be ignored.
+# Default is auto to automatically determine the status
+# of the peer.
+#
+#
+# ==== SSL / HTTPS / TLS OPTIONS ====
+#
+# ssl Encrypt connections to this peer with SSL/TLS.
+#
+# sslcert=/path/to/ssl/certificate
+# A client SSL certificate to use when connecting to
+# this peer.
+#
+# sslkey=/path/to/ssl/key
+# The private SSL key corresponding to sslcert above.
+# If 'sslkey' is not specified 'sslcert' is assumed to
+# reference a combined file containing both the
+# certificate and the key.
+#
+# sslversion=1|2|3|4
+# The SSL version to use when connecting to this peer
+# 1 = automatic (default)
+# 2 = SSL v2 only
+# 3 = SSL v3 only
+# 4 = TLS v1 only
+#
+# sslcipher=... The list of valid SSL ciphers to use when connecting
+# to this peer.
+#
+# ssloptions=... Specify various SSL engine options:
+# NO_SSLv2 Disallow the use of SSLv2
+# NO_SSLv3 Disallow the use of SSLv3
+# NO_TLSv1 Disallow the use of TLSv1
+# See src/ssl_support.c or the OpenSSL documentation for
+# a more complete list.
+#
+# sslcafile=... A file containing additional CA certificates to use
+# when verifying the peer certificate.
+#
+# sslcapath=... A directory containing additional CA certificates to
+# use when verifying the peer certificate.
+#
+# sslcrlfile=... A certificate revocation list file to use when
+# verifying the peer certificate.
+#
+# sslflags=... Specify various flags modifying the SSL implementation:
+#
+# DONT_VERIFY_PEER
+# Accept certificates even if they fail to
+# verify.
+# NO_DEFAULT_CA
+# Don't use the default CA list built in
+# to OpenSSL.
+# DONT_VERIFY_DOMAIN
+# Don't verify the peer certificate
+# matches the server name
+#
+# ssldomain= The peer name as advertised in it's certificate.
+# Used for verifying the correctness of the received peer
+# certificate. If not specified the peer hostname will be
+# used.
+#
+# front-end-https
+# Enable the "Front-End-Https: On" header needed when
+# using Squid as a SSL frontend in front of Microsoft OWA.
+# See MS KB document Q307347 for details on this header.
+# If set to auto the header will only be added if the
+# request is forwarded as a https:// URL.
+#
+#
+# ==== GENERAL OPTIONS ====
+#
+# connect-timeout=N
+# A peer-specific connect timeout.
+# Also see the peer_connect_timeout directive.
+#
+# connect-fail-limit=N
+# How many times connecting to a peer must fail before
+# it is marked as down. Default is 10.
+#
+# allow-miss Disable Squid's use of only-if-cached when forwarding
+# requests to siblings. This is primarily useful when
+# icp_hit_stale is used by the sibling. To extensive use
+# of this option may result in forwarding loops, and you
+# should avoid having two-way peerings with this option.
+# For example to deny peer usage on requests from peer
+# by denying cache_peer_access if the source is a peer.
+#
+# max-conn=N Limit the amount of connections Squid may open to this
+# peer. see also
+#
+# name=xxx Unique name for the peer.
+# Required if you have multiple peers on the same host
+# but different ports.
+# This name can be used in cache_peer_access and similar
+# directives to dentify the peer.
+# Can be used by outgoing access controls through the
+# peername ACL type.
+#
+# no-tproxy Do not use the client-spoof TPROXY support when forwarding
+# requests to this peer. Use normal address selection instead.
+#
+# proxy-only objects fetched from the peer will not be stored locally.
+#
+#Default:
+# none
+
+# TAG: cache_peer_domain
+# Use to limit the domains for which a neighbor cache will be
+# queried. Usage:
+#
+# cache_peer_domain cache-host domain [domain ...]
+# cache_peer_domain cache-host !domain
+#
+# For example, specifying
+#
+# cache_peer_domain parent.foo.net .edu
+#
+# has the effect such that UDP query packets are sent to
+# 'bigserver' only when the requested object exists on a
+# server in the .edu domain. Prefixing the domainname
+# with '!' means the cache will be queried for objects
+# NOT in that domain.
+#
+# NOTE: * Any number of domains may be given for a cache-host,
+# either on the same or separate lines.
+# * When multiple domains are given for a particular
+# cache-host, the first matched domain is applied.
+# * Cache hosts with no domain restrictions are queried
+# for all requests.
+# * There are no defaults.
+# * There is also a 'cache_peer_access' tag in the ACL
+# section.
+#Default:
+# none
+
+# TAG: cache_peer_access
+# Similar to 'cache_peer_domain' but provides more flexibility by
+# using ACL elements.
+#
+# cache_peer_access cache-host allow|deny [!]aclname ...
+#
+# The syntax is identical to 'http_access' and the other lists of
+# ACL elements. See the comments for 'http_access' below, or
+# the Squid FAQ (http://wiki.squid-cache.org/SquidFaq/SquidAcl).
+#Default:
+# none
+
+# TAG: neighbor_type_domain
+# usage: neighbor_type_domain neighbor parent|sibling domain domain ...
+#
+# Modifying the neighbor type for specific domains is now
+# possible. You can treat some domains differently than the the
+# default neighbor type specified on the 'cache_peer' line.
+# Normally it should only be necessary to list domains which
+# should be treated differently because the default neighbor type
+# applies for hostnames which do not match domains listed here.
+#
+#EXAMPLE:
+# cache_peer cache.foo.org parent 3128 3130
+# neighbor_type_domain cache.foo.org sibling .com .net
+# neighbor_type_domain cache.foo.org sibling .au .de
+#Default:
+# none
+
+# TAG: dead_peer_timeout (seconds)
+# This controls how long Squid waits to declare a peer cache
+# as "dead." If there are no ICP replies received in this
+# amount of time, Squid will declare the peer dead and not
+# expect to receive any further ICP replies. However, it
+# continues to send ICP queries, and will mark the peer as
+# alive upon receipt of the first subsequent ICP reply.
+#
+# This timeout also affects when Squid expects to receive ICP
+# replies from peers. If more than 'dead_peer' seconds have
+# passed since the last ICP reply was received, Squid will not
+# expect to receive an ICP reply on the next query. Thus, if
+# your time between requests is greater than this timeout, you
+# will see a lot of requests sent DIRECT to origin servers
+# instead of to your parents.
+#Default:
+# dead_peer_timeout 10 seconds
+
+# TAG: forward_max_tries
+# Controls how many different forward paths Squid will try
+# before giving up. See also forward_timeout.
+#Default:
+# forward_max_tries 10
+
+# TAG: hierarchy_stoplist
+# A list of words which, if found in a URL, cause the object to
+# be handled directly by this cache. In other words, use this
+# to not query neighbor caches for certain objects. You may
+# list this option multiple times.
+#
+# Example:
+# hierarchy_stoplist cgi-bin ?
+#
+# Note: never_direct overrides this option.
+#Default:
+# none
+
+# MEMORY CACHE OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: cache_mem (bytes)
+# NOTE: THIS PARAMETER DOES NOT SPECIFY THE MAXIMUM PROCESS SIZE.
+# IT ONLY PLACES A LIMIT ON HOW MUCH ADDITIONAL MEMORY SQUID WILL
+# USE AS A MEMORY CACHE OF OBJECTS. SQUID USES MEMORY FOR OTHER
+# THINGS AS WELL. SEE THE SQUID FAQ SECTION 8 FOR DETAILS.
+#
+# 'cache_mem' specifies the ideal amount of memory to be used
+# for:
+# * In-Transit objects
+# * Hot Objects
+# * Negative-Cached objects
+#
+# Data for these objects are stored in 4 KB blocks. This
+# parameter specifies the ideal upper limit on the total size of
+# 4 KB blocks allocated. In-Transit objects take the highest
+# priority.
+#
+# In-transit objects have priority over the others. When
+# additional space is needed for incoming data, negative-cached
+# and hot objects will be released. In other words, the
+# negative-cached and hot objects will fill up any unused space
+# not needed for in-transit objects.
+#

+# heap LFUDA: Least Frequently Used with Dynamic Aging
+# heap LRU : LRU policy implemented using a heap
+#
+# Applies to any cache_dir lines listed below this.
+#
+# The LRU policies keeps recently referenced objects.
+#
+# The heap GDSF policy optimizes object hit rate by keeping smaller
+# popular objects in cache so it has a better chance of getting a
+# hit. It achieves a lower byte hit rate than LFUDA though since
+# it evicts larger (possibly popular) objects.
+#
+# The heap LFUDA policy keeps popular objects in cache regardless of
+# their size and thus optimizes byte hit rate at the expense of
+# hit rate since one large, popular object will prevent many
+# smaller, slightly less popular objects from being cached.
+#
+# Both policies utilize a dynamic aging mechanism that prevents
+# cache pollution that can otherwise occur with frequency-based

+# for caching, this can be the mount-point directory.
+# The directory must exist and be writable by the Squid
+# process. Squid will NOT create this directory for you.

+# "ufs" is the old well-known Squid storage format that has always
+# been there.
+#
+# cache_dir ufs Directory-Name Mbytes L1 L2 [options]
+#
+# 'Mbytes' is the amount of disk space (MB) to use under this

+#
+# 'L2' is the number of second-level subdirectories which
+# will be created under each first-level directory. The default
+# is 256.
+#
+# The aufs store type:
+#
+# "aufs" uses the same storage format as "ufs", utilizing

+#
+# cache_dir diskd Directory-Name Mbytes L1 L2 [options] [Q1=n] [Q2=n]
+#
+# see argument descriptions under ufs above
+#
+# Q1 specifies the number of unacknowledged I/O requests when Squid

+# size of the COSS partition. The default is 512 bytes, which
+# leads to a maximum cache_dir size of 512<<24, or 8 GB. Note
+# you should not change the coss block size after Squid
+# has written some objects to the cache_dir.
+#
+# The coss file store has changed from 2.5. Now it uses a file
+# called 'stripe' in the directory names in the config - and
+# this will be created by squid -z.
+#
+# Common options:
+#
+# no-store, no new objects should be stored to this cache_dir
+#
+# max-size=n, refers to the max object size in bytes this cache_dir
+# supports. It is used to select the cache_dir to store the object.
+# Note: To make optimal use of the max-size limits you should order
+# the cache_dir lines with the smallest max-size value first and the
+# ones with no max-size specification last.

+#
+# NOTE: The default value is intended to be much larger than any

+#
+# By default, Squid will immediately close client connections when

+#
+# Change this option to 'on' and Squid will keep open connections

+# DELAY POOL PARAMETERS
+# -----------------------------------------------------------------------------
+
+# TAG: delay_pools
+# This represents the number of delay pools to be used. For example,
+# if you have one class 2 delay pool and one class 3 delays pool, you
+# have a total of 2 delay pools.
+#Default:
+# delay_pools 0
+
+# TAG: delay_class
+# This defines the class of each delay pool. There must be exactly one
+# delay_class line for each delay pool. For example, to define two
+# delay pools, one of class 2 and one of class 3, the settings above
+# and here would be:
+#
+# Example:
+# delay_pools 4 # 4 delay pools
+# delay_class 1 2 # pool 1 is a class 2 pool
+# delay_class 2 3 # pool 2 is a class 3 pool
+# delay_class 3 4 # pool 3 is a class 4 pool
+# delay_class 4 5 # pool 4 is a class 5 pool
+#
+# The delay pool classes are:
+#
+# class 1 Everything is limited by a single aggregate
+# bucket.
+#
+# class 2 Everything is limited by a single aggregate
+# bucket as well as an "individual" bucket chosen
+# from bits 25 through 32 of the IPv4 address.
+#
+# class 3 Everything is limited by a single aggregate
+# bucket as well as a "network" bucket chosen
+# from bits 17 through 24 of the IP address and a
+# "individual" bucket chosen from bits 17 through
+# 32 of the IPv4 address.
+#
+# class 4 Everything in a class 3 delay pool, with an
+# additional limit on a per user basis. This
+# only takes effect if the username is established
+# in advance - by forcing authentication in your
+# http_access rules.
+#
+# class 5 Requests are grouped according their tag (see
+# external_acl's tag= reply).
+#
+#
+# Each pool also requires a delay_parameters directive to configure the pool size
+# and speed limits used whenever the pool is applied to a request. Along with
+# a set of delay_access directives to determine when it is used.
+#
+# NOTE: If an IP address is a.b.c.d
+# -> bits 25 through 32 are "d"
+# -> bits 17 through 24 are "c"
+# -> bits 17 through 32 are "c * 256 + d"
+#
+# NOTE-2: Due to the use of bitmasks in class 2,3,4 pools they only apply to
+# IPv4 traffic. Class 1 and 5 pools may be used with IPv6 traffic.
+#Default:
+# none
+
+# TAG: delay_access
+# This is used to determine which delay pool a request falls into.
+#
+# delay_access is sorted per pool and the matching starts with pool 1,
+# then pool 2, ..., and finally pool N. The first delay pool where the
+# request is allowed is selected for the request. If it does not allow
+# the request to any pool then the request is not delayed (default).
+#
+# For example, if you want some_big_clients in delay
+# pool 1 and lotsa_little_clients in delay pool 2:
+#
+#Example:
+# delay_access 1 allow some_big_clients
+# delay_access 1 deny all
+# delay_access 2 allow lotsa_little_clients
+# delay_access 2 deny all
+# delay_access 3 allow authenticated_clients
+#Default:
+# none
+
+# TAG: delay_parameters
+# This defines the parameters for a delay pool. Each delay pool has
+# a number of "buckets" associated with it, as explained in the
+# description of delay_class.
+#
+# For a class 1 delay pool, the syntax is:
+# delay_pools pool 1
+# delay_parameters pool aggregate
+#
+# For a class 2 delay pool:
+# delay_pools pool 2
+# delay_parameters pool aggregate individual
+#
+# For a class 3 delay pool:
+# delay_pools pool 3
+# delay_parameters pool aggregate network individual
+#
+# For a class 4 delay pool:
+# delay_pools pool 4
+# delay_parameters pool aggregate network individual user
+#
+# For a class 5 delay pool:
+# delay_pools pool 5
+# delay_parameters pool tagrate
+#
+# The option variables are:
+#
+# pool a pool number - ie, a number between 1 and the
+# number specified in delay_pools as used in
+# delay_class lines.
+#
+# aggregate the speed limit parameters for the aggregate bucket
+# (class 1, 2, 3).
+#
+# individual the speed limit parameters for the individual
+# buckets (class 2, 3).
+#
+# network the speed limit parameters for the network buckets
+# (class 3).
+#
+# user the speed limit parameters for the user buckets
+# (class 4).
+#
+# tagrate the speed limit parameters for the tag buckets
+# (class 5).
+#
+# A pair of delay parameters is written restore/maximum, where restore is
+# the number of bytes (not bits - modem and network speeds are usually
+# quoted in bits) per second placed into the bucket, and maximum is the
+# maximum number of bytes which can be in the bucket at any time.
+#
+# There must be one delay_parameters line for each delay pool.
+#
+#
+# For example, if delay pool number 1 is a class 2 delay pool as in the
+# above example, and is being used to strictly limit each host to 64Kbit/sec
+# (plus overheads), with no overall limit, the line is:
+#
+# delay_parameters 1 -1/-1 8000/8000
+#
+# Note that 8 x 8000 KByte/sec -> 64Kbit/sec.
+#
+# Note that the figure -1 is used to represent "unlimited".
+#
+#
+# And, if delay pool number 2 is a class 3 delay pool as in the above
+# example, and you want to limit it to a total of 256Kbit/sec (strict limit)
+# with each 8-bit network permitted 64Kbit/sec (strict limit) and each
+# individual host permitted 4800bit/sec with a bucket maximum size of 64Kbits
+# to permit a decent web page to be downloaded at a decent speed
+# (if the network is not being limited due to overuse) but slow down
+# large downloads more significantly:
+#
+# delay_parameters 2 32000/32000 8000/8000 600/8000
+#
+# Note that 8 x 32000 KByte/sec -> 256Kbit/sec.
+# 8 x 8000 KByte/sec -> 64Kbit/sec.
+# 8 x 600 Byte/sec -> 4800bit/sec.
+#
+#
+# Finally, for a class 4 delay pool as in the example - each user will
+# be limited to 128Kbits/sec no matter how many workstations they are logged into.:
+#
+# delay_parameters 4 32000/32000 8000/8000 600/64000 16000/16000
+#Default:
+# none
+
+# TAG: delay_initial_bucket_level (percent, 0-100)
+# The initial bucket percentage is used to determine how much is put
+# in each bucket when squid starts, is reconfigured, or first notices
+# a host accessing it (in class 2 and class 3, individual hosts and

+# -----------------------------------------------------------------------------
+
+# TAG: nonhierarchical_direct
+# By default, Squid will send any non-hierarchical requests
+# (matching hierarchy_stoplist or not cacheable request type) direct
+# to origin servers.
+#
+# If you set this to off, Squid will prefer to send these
+# requests to parents.
+#
+# Note that in most configurations, by turning this off you will only
+# add latency to these request without any improvement in global hit
+# ratio.
+#
+# If you are inside an firewall see never_direct instead of
+# this directive.
+#Default:
+# nonhierarchical_direct on
+
+# TAG: prefer_direct
+# Normally Squid tries to use parents for most requests. If you for some
+# reason like it to first try going direct and only use a parent if
+# going direct fails set this to on.
+#
+# By combining nonhierarchical_direct off and prefer_direct on you
+# can set up Squid to use a parent as a backup path if going direct
+# fails.
+#
+# Note: If you want Squid to use parents for all requests see
+# the never_direct directive. prefer_direct only modifies how Squid
+# acts on cacheable requests.
+#Default:
+# prefer_direct off
+
+# TAG: always_direct
+# Usage: always_direct allow|deny [!]aclname ...
+#
+# Here you can use ACL elements to specify requests which should
+# ALWAYS be forwarded by Squid to the origin servers without using
+# any peers. For example, to always directly forward requests for
+# local servers ignoring any parents or siblings you may have use
+# something like:
+#
+# acl local-servers dstdomain my.domain.net
+# always_direct allow local-servers
+#
+# To always forward FTP requests directly, use
+#
+# acl FTP proto FTP
+# always_direct allow FTP
+#
+# NOTE: There is a similar, but opposite option named
+# 'never_direct'. You need to be aware that "always_direct deny
+# foo" is NOT the same thing as "never_direct allow foo". You
+# may need to use a deny rule to exclude a more-specific case of
+# some other rule. Example:
+#
+# acl local-external dstdomain external.foo.net
+# acl local-servers dstdomain .foo.net
+# always_direct deny local-external
+# always_direct allow local-servers
+#
+# NOTE: If your goal is to make the client forward the request
+# directly to the origin server bypassing Squid then this needs
+# to be done in the client configuration. Squid configuration
+# can only tell Squid how Squid should fetch the object.
+#
+# NOTE: This directive is not related to caching. The replies
+# is cached as usual even if you use always_direct. To not cache
+# the replies see the 'cache' directive.
+#
+# This clause supports both fast and slow acl types.
+# See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
+#Default:
+# none
+
+# TAG: never_direct
+# Usage: never_direct allow|deny [!]aclname ...
+#
+# never_direct is the opposite of always_direct. Please read
+# the description for always_direct if you have not already.
+#
+# With 'never_direct' you can use ACL elements to specify
+# requests which should NEVER be forwarded directly to origin
+# servers. For example, to force the use of a proxy for all
+# requests, except those in your local domain use something like:
+#
+# acl local-servers dstdomain .foo.net
+# never_direct deny local-servers
+# never_direct allow all
+#
+# or if Squid is inside a firewall and there are local intranet
+# servers inside the firewall use something like:
+#
+# acl local-intranet dstdomain .foo.net
+# acl local-external dstdomain external.foo.net
+# always_direct deny local-external
+# always_direct allow local-intranet
+# never_direct allow all

+
+# TAG: client_db on|off
+# If you want to disable collecting per-client statistics,
+# turn off client_db here.
+#Default:
+# client_db on
+
+# TAG: refresh_all_ims on|off
+# When you enable this option, squid will always check
+# the origin server for an update when a client sends an
+# If-Modified-Since request. Many browsers use IMS
+# requests when the user requests a reload, and this
+# ensures those clients receive the latest version.
+#
+# By default (off), squid may return a Not Modified response
+# based on the age of the cached version.
+#Default:
+# refresh_all_ims off
+
+# TAG: reload_into_ims on|off
+# When you enable this option, client no-cache or ``reload''
+# requests will be changed to If-Modified-Since requests.
+# Doing this VIOLATES the HTTP standard. Enabling this
+# feature could make you liable for problems which it
+# causes.
+#
+# see also refresh_pattern for a more selective approach.
+#Default:
+# reload_into_ims off
+
+# TAG: maximum_single_addr_tries
+# This sets the maximum number of connection attempts for a
+# host that only has one address (for multiple-address hosts,
+# each address is tried once).
+#
+# The default value is one attempt, the (not recommended)
+# maximum is 255 tries. A warning message will be generated
+# if it is set to a value greater than ten.
+#
+# Note: This is in addition to the request re-forwarding which
+# takes place if Squid fails to get a satisfying response.
+#Default:
+# maximum_single_addr_tries 1
+
+# TAG: retry_on_error
+# If set to ON Squid will automatically retry requests when
+# receiving an error response with status 403 (Forbidden),
+# 500 (Internal Error), 501 or 503 (Service not available).
+# Status 502 and 504 (Gateway errors) are always retried.
+#
+# This is mainly useful if you are in a complex cache hierarchy to
+# work around access control errors.
+#
+# NOTE: This retry will attempt to find another working destination.
+# Which is different from the server which just failed.
+#Default:
+# retry_on_error off
+
+# TAG: as_whois_server
+# WHOIS server to query for AS numbers. NOTE: AS numbers are
+# queried only when Squid starts up, not for every request.
+#Default:
+# as_whois_server whois.ra.net
+
+# TAG: offline_mode
+# Enable this option and Squid will never try to validate cached
+# objects.
+#Default:
+# offline_mode off
+
+# TAG: uri_whitespace
+# What to do with requests that have whitespace characters in the
+# URI. Options:
+#
+# strip: The whitespace characters are stripped out of the URL.
+# This is the behavior recommended by RFC2396.
+# deny: The request is denied. The user receives an "Invalid
+# Request" message.
+# allow: The request is allowed and the URI is not changed. The
+# whitespace characters remain in the URI. Note the
+# whitespace is passed to redirector processes if they
+# are in use.
+# encode: The request is allowed and the whitespace characters are
+# encoded according to RFC1738. This could be considered
+# a violation of the HTTP/1.1
+# RFC because proxies are not allowed to rewrite URI's.
+# chop: The request is allowed and the URI is chopped at the
+# first whitespace. This might also be considered a
+# violation.
+#Default:
+# uri_whitespace strip
+
+# TAG: chroot
+# Specifies a directory where Squid should do a chroot() while
+# initializing. This also causes Squid to fully drop root
+# privileges after initializing. This means, for example, if you
+# use a HTTP port less than 1024 and try to reconfigure, you may
+# get an error saying that Squid can not open the port.
+#Default:
+# none
+
+# TAG: balance_on_multiple_ip
+# Modern IP resolvers in squid sort lookup results by preferred access.
+# By default squid will use these IP in order and only rotates to
+# the next listed when the most preffered fails.
+#
+# Some load balancing servers based on round robin DNS have been
+# found not to preserve user session state across requests
+# to different IP addresses.
+#
+# Enabling this directive Squid rotates IP's per request.
+#Default:
+# balance_on_multiple_ip off
+
+# TAG: pipeline_prefetch
+# To boost the performance of pipelined requests to closer
+# match that of a non-proxied environment Squid can try to fetch
+# up to two requests in parallel from a pipeline.
+#
+# Defaults to off for bandwidth management and access logging
+# reasons.
+#
+# WARNING: pipelining breaks NTLM and Negotiate/Kerberos authentication.
+#Default:
+# pipeline_prefetch off
+
+# TAG: high_response_time_warning (msec)
+# If the one-minute median response time exceeds this value,
+# Squid prints a WARNING with debug level 0 to get the
+# administrators attention. The value is in milliseconds.
+#Default:
+# high_response_time_warning 0
+
+# TAG: high_page_fault_warning
+# If the one-minute average page fault rate exceeds this
+# value, Squid prints a WARNING with debug level 0 to get
+# the administrators attention. The value is in page faults
+# per second.
+#Default:
+# high_page_fault_warning 0
+
+# TAG: high_memory_warning
+# If the memory usage (as determined by mallinfo) exceeds
+# this amount, Squid prints a WARNING with debug level 0 to get
+# the administrators attention.
+#Default:
+# high_memory_warning 0 KB
+
+# TAG: sleep_after_fork (microseconds)
+# When this is set to a non-zero value, the main Squid process
+# sleeps the specified number of microseconds after a fork()
+# system call. This sleep may help the situation where your
+# system reports fork() failures due to lack of (virtual)
+# memory. Note, however, if you have a lot of child
+# processes, these sleep delays will add up and your
+# Squid will not service requests for some amount of time
+# until all the child processes have been started.
+# On Windows value less then 1000 (1 milliseconds) are
+# rounded to 1000.
+#Default:
+# sleep_after_fork 0
+
+# TAG: windows_ipaddrchangemonitor on|off
+# On Windows Squid by default will monitor IP address changes and will
+# reconfigure itself after any detected event. This is very useful for
+# proxies connected to internet with dial-up interfaces.
+# In some cases (a Proxy server acting as VPN gateway is one) it could be
+# desiderable to disable this behaviour setting this to 'off'.
+# Note: after changing this, Squid service must be restarted.
+#Default:
+# windows_ipaddrchangemonitor on
+
+# TAG: max_filedescriptors
+# The maximum number of filedescriptors supported.
+#
+# The default "0" means Squid inherits the current ulimit setting.
+#
+# Note: Changing this requires a restart of Squid. Also
+# not all comm loops supports large values.
+#Default:
+# max_filedescriptors 0

+# WELCOME TO SQUID 3.1.20
+# ----------------------------
+#
+# This is the documentation for the Squid configuration file.
+# This documentation can also be found online at:
+# http://www.squid-cache.org/Doc/config/
+#
+# You may wish to look at the Squid home page and wiki for the
+# FAQ and other documentation:
+# http://www.squid-cache.org/
+# http://wiki.squid-cache.org/SquidFaq
+# http://wiki.squid-cache.org/ConfigExamples
+#
+# This documentation shows what the defaults for various directives
+# happen to be. If you don't need to change the default, you should
+# leave the line out of your squid.conf in most cases.
+#
+# In some cases "none" refers to no default setting at all,
+# while in other cases it refers to the value of the option
+# - the comments for that keyword indicate if this is the case.
+#
+
+# Configuration options can be included using the "include" directive.
+# Include takes a list of files to include. Quoting and wildcards are
+# supported.
+#
+# For example,
+#
+# include /path/to/included/file/squid.acl.config
+#
+# Includes can be nested up to a hard-coded depth of 16 levels.
+# This arbitrary restriction is to prevent recursive include references
+# from causing Squid entering an infinite loop whilst trying to load
+# configuration files.
+
+# TAG: dns_testnames
+# Remove this line. DNS is no longer tested on startup.
+#Default:
+# none
+
+# TAG: extension_methods
+# Remove this line. All valid methods for HTTP are accepted by default.
+#Default:
+# none
+
+# TAG: incoming_rate
+#Default:
+# none
+
+# TAG: server_http11
+# Remove this line. HTTP/1.1 is supported by default.
+#Default:
+# none
+
+# TAG: upgrade_http0.9
+# Remove this line. ICY/1.0 streaming protocol is supported by default.
+#Default:
+# none
+
+# TAG: zph_local
+# Alter these entries. Use the qos_flows directive instead.
+#Default:
+# none
+
+# TAG: header_access
+# Since squid-3.0 replace with request_header_access or reply_header_access
+# depending on whether you wish to match client requests or server replies.
+#Default:
+# none
+
+# TAG: httpd_accel_no_pmtu_disc
+# Since squid-3.0 use the 'disable-pmtu-discovery' flag on http_port instead.
+#Default:
+# none
+
+# OPTIONS FOR AUTHENTICATION
+# -----------------------------------------------------------------------------
+
+# TAG: auth_param
+# This is used to define parameters for the various authentication
+# schemes supported by Squid.
+#
+# format: auth_param scheme parameter [setting]
+#
+# The order in which authentication schemes are presented to the client is
+# dependent on the order the scheme first appears in config file. IE
+# has a bug (it's not RFC 2617 compliant) in that it will use the basic
+# scheme if basic is the first entry presented, even if more secure
+# schemes are presented. For now use the order in the recommended
+# settings section below. If other browsers have difficulties (don't
+# recognize the schemes offered even if you are using basic) either
+# put basic first, or disable the other schemes (by commenting out their
+# program entry).
+#
+# Once an authentication scheme is fully configured, it can only be
+# shutdown by shutting squid down and restarting. Changes can be made on
+# the fly and activated with a reconfigure. I.E. You can change to a
+# different helper, but not unconfigure the helper completely.
+#
+# Please note that while this directive defines how Squid processes
+# authentication it does not automatically activate authentication.
+# To use authentication you must in addition make use of ACLs based
+# on login name in http_access (proxy_auth, proxy_auth_regex or
+# external with %LOGIN used in the format tag). The browser will be
+# challenged for authentication on the first such acl encountered
+# in http_access processing and will also be re-challenged for new
+# login credentials if the request is being denied by a proxy_auth
+# type acl.
+#
+# WARNING: authentication can't be used in a transparently intercepting
+# proxy as the client then thinks it is talking to an origin server and
+# not the proxy. This is a limitation of bending the TCP/IP protocol to
+# transparently intercepting port 80, not a limitation in Squid.
+# Ports flagged 'transparent', 'intercept', or 'tproxy' have
+# authentication disabled.
+#
+# === Parameters for the basic scheme follow. ===
+#
+# "program" cmdline
+# Specify the command for the external authenticator. Such a program
+# reads a line containing "username password" and replies "OK" or
+# "ERR" in an endless loop. "ERR" responses may optionally be followed
+# by a error description available as %m in the returned error page.
+# If you use an authenticator, make sure you have 1 acl of type
+# proxy_auth.
+#
+# By default, the basic authentication scheme is not used unless a
+# program is specified.
+#
+# If you want to use the traditional NCSA proxy authentication, set
+# this line to something like
+#
+# auth_param basic program /usr/lib/squid3/ncsa_auth /usr/etc/passwd
+#
+# "utf8" on|off
+# HTTP uses iso-latin-1 as characterset, while some authentication
+# backends such as LDAP expects UTF-8. If this is set to on Squid will
+# translate the HTTP iso-latin-1 charset to UTF-8 before sending the
+# username & password to the helper.
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn. If you start too few
+# Squid will have to wait for them to process a backlog of credential
+# verifications, slowing it down. When password verifications are
+# done via a (slow) network you are likely to need lots of
+# authenticator processes.
+# auth_param basic children 5
+#
+# "concurrency" concurrency
+# The number of concurrent requests the helper can process.
+# The default of 0 is used for helpers who only supports
+# one request at a time. Setting this changes the protocol used to
+# include a channel number first on the request/response line, allowing
+# multiple requests to be sent to the same helper in parallell without
+# wating for the response.
+# Must not be set unless it's known the helper supports this.
+# auth_param basic concurrency 0
+#
+# "realm" realmstring
+# Specifies the realm name which is to be reported to the
+# client for the basic proxy authentication scheme (part of
+# the text the user will see when prompted their username and
+# password). There is no default.
+# auth_param basic realm Squid proxy-caching web server
+#
+# "credentialsttl" timetolive
+# Specifies how long squid assumes an externally validated
+# username:password pair is valid for - in other words how
+# often the helper program is called for that user. Set this
+# low to force revalidation with short lived passwords. Note
+# setting this high does not impact your susceptibility
+# to replay attacks unless you are using an one-time password
+# system (such as SecureID). If you are using such a system,
+# you will be vulnerable to replay attacks unless you also
+# use the max_user_ip ACL in an http_access rule.
+#
+# "casesensitive" on|off
+# Specifies if usernames are case sensitive. Most user databases are
+# case insensitive allowing the same username to be spelled using both
+# lower and upper case letters, but some are case sensitive. This
+# makes a big difference for user_max_ip ACL processing and similar.
+# auth_param basic casesensitive off

+# === Parameters for the digest scheme follow ===
+#
+# "program" cmdline
+# Specify the command for the external authenticator. Such
+# a program reads a line containing "username":"realm" and
+# replies with the appropriate H(A1) value hex encoded or
+# ERR if the user (or his H(A1) hash) does not exists.
+# See rfc 2616 for the definition of H(A1).
+# "ERR" responses may optionally be followed by a error description
+# available as %m in the returned error page.
+#
+# By default, the digest authentication scheme is not used unless a
+# program is specified.
+#
+# If you want to use a digest authenticator, set this line to
+# something like
+#

+#
+# "utf8" on|off
+# HTTP uses iso-latin-1 as characterset, while some authentication

+# translate the HTTP iso-latin-1 charset to UTF-8 before sending the
+# username & password to the helper.
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to

+# valid for.
+#
+# "nonce_max_count" number
+# Specifies the maximum number of times a given nonce can be
+# used.
+#
+# "nonce_strictness" on|off
+# Determines if squid requires strict increment-by-1 behavior
+# for nonce counts, or just incrementing (off - for use when
+# useragents generate nonce counts that occasionally miss 1
+# (ie, 1,2,4,6)). Default off.
+#
+# "check_nonce_count" on|off
+# This directive if set to off can disable the nonce count check
+# completely to work around buggy digest qop implementations in
+# certain mainstream browser versions. Default on to check the

+#
+# "post_workaround" on|off
+# This is a workaround to certain buggy browsers who sends

+# the same nonce as acquired earlier on a GET request.
+#
+# === NTLM scheme options follow ===
+#
+# "program" cmdline
+# Specify the command for the external NTLM authenticator.
+# Such a program reads exchanged NTLMSSP packets with

+# "program" cmdline
+# Specify the command for the external Negotiate authenticator.
+# This protocol is used in Microsoft Active-Directory enabled setups with
+# the Microsoft Internet Explorer or Mozilla Firefox browsers.
+# Its main purpose is to exchange credentials with the Squid proxy

+# Requests may pass through a chain of several other proxies
+# before reaching us. The X-Forwarded-For header will contain a
+# comma-separated list of the IP addresses in the chain, with the
+# rightmost address being the most recent.
+#
+# If a request reaches us from a source that is allowed by this
+# configuration item, then we consult the X-Forwarded-For header
+# to see where that host received the request from. If the
+# X-Forwarded-For header contains multiple addresses, we continue
+# backtracking until we reach an address for which we are not allowed
+# to follow the X-Forwarded-For header, or until we reach the first
+# address in the list. For the purpose of ACL used in the
+# follow_x_forwarded_for directive the src ACL type always matches
+# the address we are testing and srcdomain matches its rDNS.
+#
+# The end result of this process is an IP address that we will
+# refer to as the indirect client address. This address may
+# be treated as the client address for access control, ICAP, delay

+# will use the incorrect information as if it were the

+# Use this ACL to bypass server certificate validation errors.
+#
+# For example, the following lines will bypass all validation errors
+# when talking to servers located at 172.16.0.0/16. All other

+# sslproxy_cert_error deny all
+#
+# This clause only supports fast acl types.
+# See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
+# Using slow acl types may result in server crashes
+#
+# Without this option, all server certificate validation errors
+# terminate the transaction. Bypassing validation errors is dangerous
+# because an error usually implies that the server cannot be trusted and
+# the connection may be insecure.

+#
+# Specify a program used for entering SSL key passphrases

+#OPTIONS RELATING TO EXTERNAL SSL_CRTD
+#-----------------------------------------------------------------------------
+
+# TAG: sslcrtd_program
+# Note: This option is only available if Squid is rebuilt with the
+# -DUSE_SSL_CRTD define
+#
+# Specify the location and options of the executable for ssl_crtd process.

+
+# OPTIONS WHICH AFFECT THE NEIGHBOR SELECTION ALGORITHM
+# -----------------------------------------------------------------------------
+
+# TAG: cache_peer
+# To specify other caches in a hierarchy, use the format:
+#
+# cache_peer hostname type http-port icp-port [options]
+#
+# For example,
+#
+# # proxy icp
+# # hostname type port port options
+# # -------------------- -------- ----- ----- -----------
+# cache_peer parent.foo.net parent 3128 3130 default
+# cache_peer sib1.foo.net sibling 3128 3130 proxy-only
+# cache_peer sib2.foo.net sibling 3128 3130 proxy-only
+# cache_peer example.com parent 80 0 default
+# cache_peer cdn.example.com sibling 3128 0
+#
+# type: either 'parent', 'sibling', or 'multicast'.
+#
+# proxy-port: The port number where the peer accept HTTP requests.
+# For other Squid proxies this is usually 3128
+# For web servers this is usually 80
+#
+# icp-port: Used for querying neighbor caches about objects.
+# Set to 0 if the peer does not support ICP or HTCP.
+# See ICP and HTCP options below for additional details.
+#
+#
+# ==== ICP OPTIONS ====
+#
+# You MUST also set icp_port and icp_access explicitly when using these options.
+# The defaults will prevent peer traffic using ICP.
+#
+#
+# no-query Disable ICP queries to this neighbor.
+#
+# multicast-responder
+# Indicates the named peer is a member of a multicast group.
+# ICP queries will not be sent directly to the peer, but ICP
+# replies will be accepted from it.
+#
+# closest-only Indicates that, for ICP_OP_MISS replies, we'll only forward
+# CLOSEST_PARENT_MISSes and never FIRST_PARENT_MISSes.
+#
+# background-ping
+# To only send ICP queries to this neighbor infrequently.
+# This is used to keep the neighbor round trip time updated
+# and is usually used in conjunction with weighted-round-robin.
+#
+#
+# ==== HTCP OPTIONS ====
+#
+# You MUST also set htcp_port and htcp_access explicitly when using these options.
+# The defaults will prevent peer traffic using HTCP.
+#
+#
+# htcp Send HTCP, instead of ICP, queries to the neighbor.
+# You probably also want to set the "icp-port" to 4827
+# instead of 3130.
+#
+# htcp-oldsquid Send HTCP to old Squid versions.
+#
+# htcp-no-clr Send HTCP to the neighbor but without
+# sending any CLR requests. This cannot be used with
+# htcp-only-clr.
+#
+# htcp-only-clr Send HTCP to the neighbor but ONLY CLR requests.
+# This cannot be used with htcp-no-clr.
+#
+# htcp-no-purge-clr
+# Send HTCP to the neighbor including CLRs but only when
+# they do not result from PURGE requests.
+#
+# htcp-forward-clr
+# Forward any HTCP CLR requests this proxy receives to the peer.
+#
+#
+# ==== PEER SELECTION METHODS ====
+#
+# The default peer selection method is ICP, with the first responding peer
+# being used as source. These options can be used for better load balancing.
+#
+#
+# default This is a parent cache which can be used as a "last-resort"
+# if a peer cannot be located by any of the peer-selection methods.
+# If specified more than once, only the first is used.
+#
+# round-robin Load-Balance parents which should be used in a round-robin
+# fashion in the absence of any ICP queries.
+# weight=N can be used to add bias.
+#
+# weighted-round-robin
+# Load-Balance parents which should be used in a round-robin
+# fashion with the frequency of each parent being based on the
+# round trip time. Closer parents are used more often.
+# Usually used for background-ping parents.
+# weight=N can be used to add bias.
+#
+# carp Load-Balance parents which should be used as a CARP array.
+# The requests will be distributed among the parents based on the
+# CARP load balancing hash function based on their weight.
+#
+# userhash Load-balance parents based on the client proxy_auth or ident username.
+#
+# sourcehash Load-balance parents based on the client source IP.
+#
+# multicast-siblings
+# To be used only for cache peers of type "multicast".
+# ALL members of this multicast group have "sibling"
+# relationship with it, not "parent". This is to a multicast
+# group when the requested object would be fetched only from
+# a "parent" cache, anyway. It's useful, e.g., when
+# configuring a pool of redundant Squid proxies, being
+# members of the same multicast group.
+#
+#
+# ==== PEER SELECTION OPTIONS ====
+#
+# weight=N use to affect the selection of a peer during any weighted
+# peer-selection mechanisms.
+# The weight must be an integer; default is 1,
+# larger weights are favored more.
+# This option does not affect parent selection if a peering
+# protocol is not in use.
+#
+# basetime=N Specify a base amount to be subtracted from round trip
+# times of parents.
+# It is subtracted before division by weight in calculating
+# which parent to fectch from. If the rtt is less than the
+# base time the rtt is set to a minimal value.
+#
+# ttl=N Specify a TTL to use when sending multicast ICP queries
+# to this address.
+# Only useful when sending to a multicast group.
+# Because we don't accept ICP replies from random
+# hosts, you must configure other group members as
+# peers with the 'multicast-responder' option.
+#
+# no-delay To prevent access to this neighbor from influencing the
+# delay pools.
+#
+# digest-url=URL Tell Squid to fetch the cache digest (if digests are
+# enabled) for this host from the specified URL rather
+# than the Squid default location.
+#
+#
+# ==== ACCELERATOR / REVERSE-PROXY OPTIONS ====
+#
+# originserver Causes this parent to be contacted as an origin server.
+# Meant to be used in accelerator setups when the peer
+# is a web server.
+#
+# forceddomain=name
+# Set the Host header of requests forwarded to this peer.
+# Useful in accelerator setups where the server (peer)
+# expects a certain domain name but clients may request
+# others. ie example.com or www.example.com
+#
+# no-digest Disable request of cache digests.
+#
+# no-netdb-exchange
+# Disables requesting ICMP RTT database (NetDB).
+#
+#
+# ==== AUTHENTICATION OPTIONS ====
+#
+# login=user:password
+# If this is a personal/workgroup proxy and your parent
+# requires proxy authentication.
+#
+# Note: The string can include URL escapes (i.e. %20 for
+# spaces). This also means % must be written as %%.
+#
+# login=PROXYPASS
+# Send login details received from client to this peer.
+# Authentication is not required, nor changed.
+#
+# Note: This will pass any form of authentication but
+# only Basic auth will work through a proxy unless the
+# connection-auth options are also used.
+#
+# login=PASS Send login details received from client to this peer.
+# Authentication is not required by this option.
+# If there are no client-provided authentication headers
+# to pass on, but username and password are available
+# from either proxy login or an external ACL user= and
+# password= result tags they may be sent instead.
+#
+# Note: To combine this with proxy_auth both proxies must
+# share the same user database as HTTP only allows for
+# a single login (one for proxy, one for origin server).
+# Also be warned this will expose your users proxy
+# password to the peer. USE WITH CAUTION
+#
+# login=*:password
+# Send the username to the upstream cache, but with a
+# fixed password. This is meant to be used when the peer
+# is in another administrative domain, but it is still
+# needed to identify each user.
+# The star can optionally be followed by some extra
+# information which is added to the username. This can
+# be used to identify this proxy to the peer, similar to
+# the login=username:password option above.
+#
+# connection-auth=on|off
+# Tell Squid that this peer does or not support Microsoft
+# connection oriented authentication, and any such
+# challenges received from there should be ignored.
+# Default is auto to automatically determine the status
+# of the peer.
+#
+#
+# ==== SSL / HTTPS / TLS OPTIONS ====
+#
+# ssl Encrypt connections to this peer with SSL/TLS.
+#
+# sslcert=/path/to/ssl/certificate
+# A client SSL certificate to use when connecting to
+# this peer.
+#
+# sslkey=/path/to/ssl/key
+# The private SSL key corresponding to sslcert above.
+# If 'sslkey' is not specified 'sslcert' is assumed to
+# reference a combined file containing both the
+# certificate and the key.
+#
+# sslversion=1|2|3|4
+# The SSL version to use when connecting to this peer
+# 1 = automatic (default)
+# 2 = SSL v2 only
+# 3 = SSL v3 only
+# 4 = TLS v1 only
+#
+# sslcipher=... The list of valid SSL ciphers to use when connecting
+# to this peer.
+#
+# ssloptions=... Specify various SSL engine options:
+# NO_SSLv2 Disallow the use of SSLv2
+# NO_SSLv3 Disallow the use of SSLv3
+# NO_TLSv1 Disallow the use of TLSv1
+# See src/ssl_support.c or the OpenSSL documentation for
+# a more complete list.
+#
+# sslcafile=... A file containing additional CA certificates to use
+# when verifying the peer certificate.
+#
+# sslcapath=... A directory containing additional CA certificates to
+# use when verifying the peer certificate.
+#
+# sslcrlfile=... A certificate revocation list file to use when
+# verifying the peer certificate.
+#
+# sslflags=... Specify various flags modifying the SSL implementation:
+#
+# DONT_VERIFY_PEER
+# Accept certificates even if they fail to
+# verify.
+# NO_DEFAULT_CA
+# Don't use the default CA list built in
+# to OpenSSL.
+# DONT_VERIFY_DOMAIN
+# Don't verify the peer certificate
+# matches the server name
+#
+# ssldomain= The peer name as advertised in it's certificate.
+# Used for verifying the correctness of the received peer
+# certificate. If not specified the peer hostname will be
+# used.
+#
+# front-end-https
+# Enable the "Front-End-Https: On" header needed when
+# using Squid as a SSL frontend in front of Microsoft OWA.
+# See MS KB document Q307347 for details on this header.
+# If set to auto the header will only be added if the
+# request is forwarded as a https:// URL.
+#
+#
+# ==== GENERAL OPTIONS ====
+#
+# connect-timeout=N
+# A peer-specific connect timeout.
+# Also see the peer_connect_timeout directive.
+#
+# connect-fail-limit=N
+# How many times connecting to a peer must fail before
+# it is marked as down. Default is 10.
+#
+# allow-miss Disable Squid's use of only-if-cached when forwarding
+# requests to siblings. This is primarily useful when
+# icp_hit_stale is used by the sibling. To extensive use
+# of this option may result in forwarding loops, and you
+# should avoid having two-way peerings with this option.
+# For example to deny peer usage on requests from peer
+# by denying cache_peer_access if the source is a peer.
+#
+# max-conn=N Limit the amount of connections Squid may open to this
+# peer. see also
+#
+# name=xxx Unique name for the peer.
+# Required if you have multiple peers on the same host
+# but different ports.
+# This name can be used in cache_peer_access and similar
+# directives to dentify the peer.
+# Can be used by outgoing access controls through the
+# peername ACL type.
+#
+# no-tproxy Do not use the client-spoof TPROXY support when forwarding
+# requests to this peer. Use normal address selection instead.
+#
+# proxy-only objects fetched from the peer will not be stored locally.
+#
+#Default:
+# none
+
+# TAG: cache_peer_domain
+# Use to limit the domains for which a neighbor cache will be
+# queried. Usage:
+#
+# cache_peer_domain cache-host domain [domain ...]
+# cache_peer_domain cache-host !domain
+#
+# For example, specifying
+#
+# cache_peer_domain parent.foo.net .edu
+#
+# has the effect such that UDP query packets are sent to
+# 'bigserver' only when the requested object exists on a
+# server in the .edu domain. Prefixing the domainname
+# with '!' means the cache will be queried for objects
+# NOT in that domain.
+#
+# NOTE: * Any number of domains may be given for a cache-host,
+# either on the same or separate lines.
+# * When multiple domains are given for a particular
+# cache-host, the first matched domain is applied.
+# * Cache hosts with no domain restrictions are queried
+# for all requests.
+# * There are no defaults.
+# * There is also a 'cache_peer_access' tag in the ACL
+# section.
+#Default:
+# none
+
+# TAG: cache_peer_access
+# Similar to 'cache_peer_domain' but provides more flexibility by
+# using ACL elements.
+#
+# cache_peer_access cache-host allow|deny [!]aclname ...
+#
+# The syntax is identical to 'http_access' and the other lists of
+# ACL elements. See the comments for 'http_access' below, or
+# the Squid FAQ (http://wiki.squid-cache.org/SquidFaq/SquidAcl).
+#Default:
+# none
+
+# TAG: neighbor_type_domain
+# usage: neighbor_type_domain neighbor parent|sibling domain domain ...
+#
+# Modifying the neighbor type for specific domains is now
+# possible. You can treat some domains differently than the the
+# default neighbor type specified on the 'cache_peer' line.
+# Normally it should only be necessary to list domains which
+# should be treated differently because the default neighbor type
+# applies for hostnames which do not match domains listed here.
+#
+#EXAMPLE:
+# cache_peer cache.foo.org parent 3128 3130
+# neighbor_type_domain cache.foo.org sibling .com .net
+# neighbor_type_domain cache.foo.org sibling .au .de
+#Default:
+# none
+
+# TAG: dead_peer_timeout (seconds)
+# This controls how long Squid waits to declare a peer cache
+# as "dead." If there are no ICP replies received in this
+# amount of time, Squid will declare the peer dead and not
+# expect to receive any further ICP replies. However, it
+# continues to send ICP queries, and will mark the peer as
+# alive upon receipt of the first subsequent ICP reply.
+#
+# This timeout also affects when Squid expects to receive ICP
+# replies from peers. If more than 'dead_peer' seconds have
+# passed since the last ICP reply was received, Squid will not
+# expect to receive an ICP reply on the next query. Thus, if
+# your time between requests is greater than this timeout, you
+# will see a lot of requests sent DIRECT to origin servers
+# instead of to your parents.
+#Default:
+# dead_peer_timeout 10 seconds
+
+# TAG: forward_max_tries
+# Controls how many different forward paths Squid will try
+# before giving up. See also forward_timeout.
+#Default:
+# forward_max_tries 10
+
+# TAG: hierarchy_stoplist
+# A list of words which, if found in a URL, cause the object to
+# be handled directly by this cache. In other words, use this
+# to not query neighbor caches for certain objects. You may
+# list this option multiple times.
+#
+# Example:
+# hierarchy_stoplist cgi-bin ?
+#
+# Note: never_direct overrides this option.
+#Default:
+# none
+
+# MEMORY CACHE OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: cache_mem (bytes)
+# NOTE: THIS PARAMETER DOES NOT SPECIFY THE MAXIMUM PROCESS SIZE.
+# IT ONLY PLACES A LIMIT ON HOW MUCH ADDITIONAL MEMORY SQUID WILL
+# USE AS A MEMORY CACHE OF OBJECTS. SQUID USES MEMORY FOR OTHER
+# THINGS AS WELL. SEE THE SQUID FAQ SECTION 8 FOR DETAILS.
+#
+# 'cache_mem' specifies the ideal amount of memory to be used
+# for:
+# * In-Transit objects
+# * Hot Objects
+# * Negative-Cached objects
+#
+# Data for these objects are stored in 4 KB blocks. This
+# parameter specifies the ideal upper limit on the total size of
+# 4 KB blocks allocated. In-Transit objects take the highest
+# priority.
+#
+# In-transit objects have priority over the others. When
+# additional space is needed for incoming data, negative-cached
+# and hot objects will be released. In other words, the
+# negative-cached and hot objects will fill up any unused space
+# not needed for in-transit objects.
+#
+# If circumstances require, this limit will be exceeded.
+# Specifically, if your incoming request rate requires more than
+# 'cache_mem' of memory to hold in-transit objects, Squid will
+# exceed this limit to satisfy the new requests. When the load
+# decreases, blocks will be freed until the high-water mark is
+# reached. Thereafter, blocks will be used to store hot
+# objects.
+#Default:
+# cache_mem 256 MB
+
+# TAG: maximum_object_size_in_memory (bytes)
+# Objects greater than this size will not be attempted to kept in
+# the memory cache. This should be set high enough to keep objects
+# accessed frequently in memory to improve performance whilst low
+# enough to keep larger objects from hoarding cache_mem.
+#Default:
+# maximum_object_size_in_memory 512 KB
+
+# TAG: memory_replacement_policy
+# The memory replacement policy parameter determines which
+# objects are purged from memory when memory space is needed.
+#
+# See cache_replacement_policy for details.
+#Default:
+# memory_replacement_policy lru
+
+# DISK CACHE OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: cache_replacement_policy
+# The cache replacement policy parameter determines which
+# objects are evicted (replaced) when disk space is needed.
+#
+# lru : Squid's original list based LRU policy
+# heap GDSF : Greedy-Dual Size Frequency
+# heap LFUDA: Least Frequently Used with Dynamic Aging
+# heap LRU : LRU policy implemented using a heap
+#
+# Applies to any cache_dir lines listed below this.
+#
+# The LRU policies keeps recently referenced objects.
+#
+# The heap GDSF policy optimizes object hit rate by keeping smaller
+# popular objects in cache so it has a better chance of getting a
+# hit. It achieves a lower byte hit rate than LFUDA though since
+# it evicts larger (possibly popular) objects.
+#
+# The heap LFUDA policy keeps popular objects in cache regardless of
+# their size and thus optimizes byte hit rate at the expense of
+# hit rate since one large, popular object will prevent many
+# smaller, slightly less popular objects from being cached.
+#
+# Both policies utilize a dynamic aging mechanism that prevents
+# cache pollution that can otherwise occur with frequency-based
+# replacement policies.
+#
+# NOTE: if using the LFUDA replacement policy you should increase
+# the value of maximum_object_size above its default of 4096 KB to
+# to maximize the potential byte hit rate improvement of LFUDA.

+# TAG: cache_dir
+# Usage:
+#
+# cache_dir Type Directory-Name Fs-specific-data [options]
+#
+# You can specify multiple cache_dir lines to spread the
+# cache among different disk partitions.
+#
+# Type specifies the kind of storage system to use. Only "ufs"
+# is built by default. To enable any of the other storage systems
+# see the --enable-storeio configure option.
+#
+# 'Directory' is a top-level directory where cache swap
+# files will be stored. If you want to use an entire disk
+# for caching, this can be the mount-point directory.
+# The directory must exist and be writable by the Squid
+# process. Squid will NOT create this directory for you.
+#
+# The ufs store type:
+#
+# "ufs" is the old well-known Squid storage format that has always
+# been there.
+#
+# cache_dir ufs Directory-Name Mbytes L1 L2 [options]
+#
+# 'Mbytes' is the amount of disk space (MB) to use under this
+# directory. The default is 100 MB. Change this to suit your
+# configuration. Do NOT put the size of your disk drive here.
+# Instead, if you want Squid to use the entire disk drive,
+# subtract 20% and use that value.
+#
+# 'L1' is the number of first-level subdirectories which
+# will be created under the 'Directory'. The default is 16.
+#
+# 'L2' is the number of second-level subdirectories which
+# will be created under each first-level directory. The default
+# is 256.
+#
+# The aufs store type:
+#
+# "aufs" uses the same storage format as "ufs", utilizing
+# POSIX-threads to avoid blocking the main Squid process on
+# disk-I/O. This was formerly known in Squid as async-io.
+#
+# cache_dir aufs Directory-Name Mbytes L1 L2 [options]
+#

+# disk-I/O.
+#
+# cache_dir diskd Directory-Name Mbytes L1 L2 [options] [Q1=n] [Q2=n]
+#
+# see argument descriptions under ufs above
+#
+# Q1 specifies the number of unacknowledged I/O requests when Squid
+# stops opening new files. If this many messages are in the queues,
+# Squid won't open new files. Default is 64
+#
+# Q2 specifies the number of unacknowledged messages when Squid

+#
+# When Q1 < Q2 (the default), the cache directory is optimized

+# time.
+#
+# The coss store type:

+#
+# block-size=n defines the "block size" for COSS cache_dir's.
+# Squid uses file numbers as block numbers. Since file numbers
+# are limited to 24 bits, the block size determines the maximum
+# size of the COSS partition. The default is 512 bytes, which
+# leads to a maximum cache_dir size of 512<<24, or 8 GB. Note
+# you should not change the coss block size after Squid
+# has written some objects to the cache_dir.
+#
+# The coss file store has changed from 2.5. Now it uses a file
+# called 'stripe' in the directory names in the config - and
+# this will be created by squid -z.
+#
+# Common options:
+#
+# no-store, no new objects should be stored to this cache_dir
+#
+# max-size=n, refers to the max object size in bytes this cache_dir
+# supports. It is used to select the cache_dir to store the object.
+# Note: To make optimal use of the max-size limits you should order
+# the cache_dir lines with the smallest max-size value first and the
+# ones with no max-size specification last.
+#
+# Note for coss, max-size must be less than COSS_MEMBUF_SZ,

+#
+# If adaptation is enabled the following two codes become available:
+#
+# adapt::sum_trs Summed adaptation transaction response
+# times recorded as a comma-separated list in
+# the order of transaction start time. Each time
+# value is recorded as an integer number,
+# representing response time of one or more
+# adaptation (ICAP or eCAP) transaction in
+# milliseconds. When a failed transaction is
+# being retried or repeated, its time is not
+# logged individually but added to the
+# replacement (next) transaction. See also:
+# adapt::all_trs.
+#
+# adapt::all_trs All adaptation transaction response times.
+# Same as adaptation_strs but response times of
+# individual transactions are never added
+# together. Instead, all transaction response
+# times are recorded individually.
+#
+# You can prefix adapt::*_trs format codes with adaptation

+#
+# ICAP processing of a single HTTP message or transaction may
+# require multiple ICAP transactions. In such cases, multiple
+# ICAP transaction log lines will correspond to a single access
+# log line.
+#
+# ICAP log uses logformat codes that make sense for an ICAP
+# transaction. Header-related codes are applied to the HTTP header
+# embedded in an ICAP server response, with the following caveats:
+# For REQMOD, there is no HTTP response header unless the ICAP
+# server performed request satisfaction. For RESPMOD, the HTTP
+# request header is the header sent to the ICAP server. For
+# OPTIONS, there are no HTTP headers.
+#
+# The following format codes are also available for ICAP logs:
+#
+# icap::<A ICAP server IP address. Similar to <A.
+#
+# icap::<service_name ICAP service name from the icap_service
+# option in Squid configuration file.
+#
+# icap::ru ICAP Request-URI. Similar to ru.
+#
+# icap::rm ICAP request method (REQMOD, RESPMOD, or
+# OPTIONS). Similar to existing rm.
+#
+# icap::>st Bytes sent to the ICAP server (TCP payload
+# only; i.e., what Squid writes to the socket).
+#
+# icap::<st Bytes received from the ICAP server (TCP
+# payload only; i.e., what Squid reads from
+# the socket).
+#
+# icap::tr Transaction response time (in
+# milliseconds). The timer starts when
+# the ICAP transaction is created and
+# stops when the transaction is completed.
+# Similar to tr.
+#
+# icap::tio Transaction I/O time (in milliseconds). The
+# timer starts when the first ICAP request
+# byte is scheduled for sending. The timers
+# stops when the last byte of the ICAP response
+# is received.
+#
+# icap::to Transaction outcome: ICAP_ERR* for all
+# transaction errors, ICAP_OPT for OPTION
+# transactions, ICAP_ECHO for 204
+# responses, ICAP_MOD for message
+# modification, and ICAP_SAT for request

+
+# TAG: cache_swap_state
+# Location for the cache "swap.state" file. This index file holds
+# the metadata of objects saved on disk. It is used to rebuild
+# the cache during startup. Normally this file resides in each
+# 'cache_dir' directory, but you may specify an alternate
+# pathname here. Note you must give a full filename, not just
+# a directory. Since this is the index for the whole object
+# list you CANNOT periodically rotate it!
+#
+# If %s can be used in the file name it will be replaced with a
+# a representation of the cache_dir name where each / is replaced
+# with '.'. This is needed to allow adding/removing cache_dir

+# better to keep these index files in each 'cache_dir' directory.
+#Default:
+# none
+
+# TAG: logfile_rotate
+# Specifies the number of logfile rotations to make when you
+# type 'squid -k rotate'. The default is 10, which will rotate
+# with extensions 0 through 9. Setting logfile_rotate to 0 will
+# disable the file name rotation, but the logfiles are still closed
+# and re-opened. This will enable you to rename the logfiles
+# yourself just before sending the rotate signal.
+#
+# Note, the 'squid -k rotate' command normally sends a USR1
+# signal to the running squid process. In certain situations
+# (e.g. on Linux with Async I/O), USR1 is used for other
+# purposes, so -k rotate uses another signal. It is best to get
+# in the habit of using 'squid -k rotate' instead of 'kill -USR1
+# <pid>'.
+#
+# Note, from Squid-3.1 this option has no effect on the cache.log,

+# The maximum amount of time a client (browser) is allowed to
+# remain connected to the cache process. This protects the Cache
+# from having a lot of sockets (and hence file descriptors) tied up
+# in a CLOSE_WAIT state from remote clients that go away without
+# properly shutting down (either because of a network failure or
+# because of a poor client implementation). The default is one
+# day, 1440 minutes.
+#
+# NOTE: The default value is intended to be much larger than any
+# client would ever need to be connected to your cache. You
+# should probably change client_lifetime only as a last resort.
+# If you seem to have many client connections tying up
+# filedescriptors, we recommend first tuning the read_timeout,
+# request_timeout, persistent_request_timeout and quick_abort values.
+#Default:
+# client_lifetime 1 day
+
+# TAG: half_closed_clients
+# Some clients may shutdown the sending side of their TCP
+# connections, while leaving their receiving sides open. Sometimes,
+# Squid can not tell the difference between a half-closed and a
+# fully-closed TCP connection.
+#
+# By default, Squid will immediately close client connections when
+# read(2) returns "no more data to read."
+#
+# Change this option to 'on' and Squid will keep open connections
+# until a read(2) or write(2) on the socket returns an error.
+# This may show some benefits for reverse proxies. But if not
+# it is recommended to leave OFF.
+#Default:
+# half_closed_clients off
+
+# TAG: pconn_timeout
+# Timeout for idle persistent connections to servers and other
+# proxies.
+#Default:
+# pconn_timeout 1 minute
+
+# TAG: ident_timeout
+# Maximum time to wait for IDENT lookups to complete.
+#
+# If this is too high, and you enabled IDENT lookups from untrusted
+# users, you might be susceptible to denial-of-service by having
+# many ident requests going at once.
+#Default:
+# ident_timeout 10 seconds
+
+# TAG: shutdown_lifetime time-units
+# When SIGTERM or SIGHUP is received, the cache is put into
+# "shutdown pending" mode until all active sockets are closed.
+# This value is the lifetime to set for all open descriptors
+# during shutdown mode. Any active clients after this many

+#Default:
+# none
+
+# TAG: mail_program
+# Email program used to send mail if the cache dies.
+# The default is "mail". The specified program must comply

+#
+# Optional command line options can be specified.
+#Default:
+# mail_program mail
+
+# TAG: cache_effective_user
+# If you start Squid as root, it will change its effective/real

+# to UID of proxy.
+# see also; cache_effective_group
+#Default:
+# cache_effective_user proxy
+
+# TAG: cache_effective_group
+# Squid sets the GID to the effective user's default group ID

+# from the groups membership.
+#
+# If you want Squid to run with a specific GID regardless of
+# the group memberships of the effective user then set this
+# to the group (or GID) you want Squid to run as. When set

+# OPTIONS FOR THE CACHE REGISTRATION SERVICE
+# -----------------------------------------------------------------------------
+#
+# This section contains parameters for the (optional) cache
+# announcement service. This service is provided to help
+# cache administrators locate one another in order to join or
+# create cache hierarchies.
+#
+# An 'announcement' message is sent (via UDP) to the registration
+# service by Squid. By default, the announcement message is NOT
+# SENT unless you enable it with 'announce_period' below.
+#
+# The announcement message includes your hostname, plus the
+# following information from this configuration file:
+#
+# http_port
+# icp_port
+# cache_mgr
+#
+# All current information is processed regularly and made
+# available on the Web at http://www.ircache.net/Cache/Tracker/.
+
+# TAG: announce_period
+# This is how frequently to send cache announcements. The
+# default is `0' which disables sending the announcement

+#
+# To enable announcing your cache, just set an announce period.
+#
+# Example:

+
+# DELAY POOL PARAMETERS
+# -----------------------------------------------------------------------------
+
+# TAG: delay_pools
+# This represents the number of delay pools to be used. For example,
+# if you have one class 2 delay pool and one class 3 delays pool, you
+# have a total of 2 delay pools.
+#Default:
+# delay_pools 0
+
+# TAG: delay_class
+# This defines the class of each delay pool. There must be exactly one
+# delay_class line for each delay pool. For example, to define two
+# delay pools, one of class 2 and one of class 3, the settings above
+# and here would be:
+#
+# Example:
+# delay_pools 4 # 4 delay pools
+# delay_class 1 2 # pool 1 is a class 2 pool
+# delay_class 2 3 # pool 2 is a class 3 pool
+# delay_class 3 4 # pool 3 is a class 4 pool
+# delay_class 4 5 # pool 4 is a class 5 pool
+#
+# The delay pool classes are:
+#
+# class 1 Everything is limited by a single aggregate
+# bucket.
+#
+# class 2 Everything is limited by a single aggregate
+# bucket as well as an "individual" bucket chosen
+# from bits 25 through 32 of the IPv4 address.
+#
+# class 3 Everything is limited by a single aggregate
+# bucket as well as a "network" bucket chosen
+# from bits 17 through 24 of the IP address and a
+# "individual" bucket chosen from bits 17 through
+# 32 of the IPv4 address.
+#
+# class 4 Everything in a class 3 delay pool, with an
+# additional limit on a per user basis. This
+# only takes effect if the username is established
+# in advance - by forcing authentication in your
+# http_access rules.
+#
+# class 5 Requests are grouped according their tag (see
+# external_acl's tag= reply).
+#
+#
+# Each pool also requires a delay_parameters directive to configure the pool size
+# and speed limits used whenever the pool is applied to a request. Along with
+# a set of delay_access directives to determine when it is used.
+#
+# NOTE: If an IP address is a.b.c.d
+# -> bits 25 through 32 are "d"
+# -> bits 17 through 24 are "c"
+# -> bits 17 through 32 are "c * 256 + d"
+#
+# NOTE-2: Due to the use of bitmasks in class 2,3,4 pools they only apply to
+# IPv4 traffic. Class 1 and 5 pools may be used with IPv6 traffic.
+#Default:
+# none
+
+# TAG: delay_access
+# This is used to determine which delay pool a request falls into.
+#
+# delay_access is sorted per pool and the matching starts with pool 1,
+# then pool 2, ..., and finally pool N. The first delay pool where the
+# request is allowed is selected for the request. If it does not allow
+# the request to any pool then the request is not delayed (default).
+#
+# For example, if you want some_big_clients in delay
+# pool 1 and lotsa_little_clients in delay pool 2:
+#
+#Example:
+# delay_access 1 allow some_big_clients
+# delay_access 1 deny all
+# delay_access 2 allow lotsa_little_clients
+# delay_access 2 deny all
+# delay_access 3 allow authenticated_clients
+#Default:
+# none
+
+# TAG: delay_parameters
+# This defines the parameters for a delay pool. Each delay pool has
+# a number of "buckets" associated with it, as explained in the
+# description of delay_class.
+#
+# For a class 1 delay pool, the syntax is:
+# delay_pools pool 1
+# delay_parameters pool aggregate
+#
+# For a class 2 delay pool:
+# delay_pools pool 2
+# delay_parameters pool aggregate individual
+#
+# For a class 3 delay pool:
+# delay_pools pool 3
+# delay_parameters pool aggregate network individual
+#
+# For a class 4 delay pool:
+# delay_pools pool 4
+# delay_parameters pool aggregate network individual user
+#
+# For a class 5 delay pool:
+# delay_pools pool 5
+# delay_parameters pool tagrate
+#
+# The option variables are:
+#
+# pool a pool number - ie, a number between 1 and the
+# number specified in delay_pools as used in
+# delay_class lines.
+#
+# aggregate the speed limit parameters for the aggregate bucket
+# (class 1, 2, 3).
+#
+# individual the speed limit parameters for the individual
+# buckets (class 2, 3).
+#
+# network the speed limit parameters for the network buckets
+# (class 3).
+#
+# user the speed limit parameters for the user buckets
+# (class 4).
+#
+# tagrate the speed limit parameters for the tag buckets
+# (class 5).
+#
+# A pair of delay parameters is written restore/maximum, where restore is
+# the number of bytes (not bits - modem and network speeds are usually
+# quoted in bits) per second placed into the bucket, and maximum is the
+# maximum number of bytes which can be in the bucket at any time.
+#
+# There must be one delay_parameters line for each delay pool.
+#
+#
+# For example, if delay pool number 1 is a class 2 delay pool as in the
+# above example, and is being used to strictly limit each host to 64Kbit/sec
+# (plus overheads), with no overall limit, the line is:
+#
+# delay_parameters 1 -1/-1 8000/8000
+#
+# Note that 8 x 8000 KByte/sec -> 64Kbit/sec.
+#
+# Note that the figure -1 is used to represent "unlimited".
+#
+#
+# And, if delay pool number 2 is a class 3 delay pool as in the above
+# example, and you want to limit it to a total of 256Kbit/sec (strict limit)
+# with each 8-bit network permitted 64Kbit/sec (strict limit) and each
+# individual host permitted 4800bit/sec with a bucket maximum size of 64Kbits
+# to permit a decent web page to be downloaded at a decent speed
+# (if the network is not being limited due to overuse) but slow down
+# large downloads more significantly:
+#
+# delay_parameters 2 32000/32000 8000/8000 600/8000
+#
+# Note that 8 x 32000 KByte/sec -> 256Kbit/sec.
+# 8 x 8000 KByte/sec -> 64Kbit/sec.
+# 8 x 600 Byte/sec -> 4800bit/sec.
+#
+#
+# Finally, for a class 4 delay pool as in the example - each user will
+# be limited to 128Kbits/sec no matter how many workstations they are logged into.:
+#
+# delay_parameters 4 32000/32000 8000/8000 600/64000 16000/16000
+#Default:
+# none
+
+# TAG: delay_initial_bucket_level (percent, 0-100)
+# The initial bucket percentage is used to determine how much is put
+# in each bucket when squid starts, is reconfigured, or first notices
+# a host accessing it (in class 2 and class 3, individual hosts and
+# networks only have buckets associated with them once they have been
+# "seen" by squid).

+# -----------------------------------------------------------------------------
+
+# TAG: nonhierarchical_direct
+# By default, Squid will send any non-hierarchical requests

+# to origin servers.
+#
+# If you set this to off, Squid will prefer to send these
+# requests to parents.
+#
+# Note that in most configurations, by turning this off you will only
+# add latency to these request without any improvement in global hit
+# ratio.
+#
+# If you are inside an firewall see never_direct instead of
+# this directive.
+#Default:
+# nonhierarchical_direct on
+
+# TAG: prefer_direct
+# Normally Squid tries to use parents for most requests. If you for some
+# reason like it to first try going direct and only use a parent if
+# going direct fails set this to on.
+#
+# By combining nonhierarchical_direct off and prefer_direct on you
+# can set up Squid to use a parent as a backup path if going direct
+# fails.
+#
+# Note: If you want Squid to use parents for all requests see
+# the never_direct directive. prefer_direct only modifies how Squid
+# acts on cacheable requests.
+#Default:
+# prefer_direct off
+
+# TAG: always_direct
+# Usage: always_direct allow|deny [!]aclname ...
+#
+# Here you can use ACL elements to specify requests which should
+# ALWAYS be forwarded by Squid to the origin servers without using
+# any peers. For example, to always directly forward requests for
+# local servers ignoring any parents or siblings you may have use
+# something like:
+#
+# acl local-servers dstdomain my.domain.net
+# always_direct allow local-servers
+#
+# To always forward FTP requests directly, use
+#
+# acl FTP proto FTP
+# always_direct allow FTP
+#
+# NOTE: There is a similar, but opposite option named
+# 'never_direct'. You need to be aware that "always_direct deny
+# foo" is NOT the same thing as "never_direct allow foo". You
+# may need to use a deny rule to exclude a more-specific case of
+# some other rule. Example:
+#
+# acl local-external dstdomain external.foo.net
+# acl local-servers dstdomain .foo.net
+# always_direct deny local-external
+# always_direct allow local-servers
+#
+# NOTE: If your goal is to make the client forward the request
+# directly to the origin server bypassing Squid then this needs
+# to be done in the client configuration. Squid configuration
+# can only tell Squid how Squid should fetch the object.
+#
+# NOTE: This directive is not related to caching. The replies
+# is cached as usual even if you use always_direct. To not cache
+# the replies see the 'cache' directive.
+#
+# This clause supports both fast and slow acl types.
+# See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
+#Default:
+# none
+
+# TAG: never_direct
+# Usage: never_direct allow|deny [!]aclname ...
+#
+# never_direct is the opposite of always_direct. Please read
+# the description for always_direct if you have not already.
+#
+# With 'never_direct' you can use ACL elements to specify
+# requests which should NEVER be forwarded directly to origin
+# servers. For example, to force the use of a proxy for all
+# requests, except those in your local domain use something like:
+#
+# acl local-servers dstdomain .foo.net
+# never_direct deny local-servers
+# never_direct allow all
+#
+# or if Squid is inside a firewall and there are local intranet
+# servers inside the firewall use something like:
+#
+# acl local-intranet dstdomain .foo.net
+# acl local-external dstdomain external.foo.net
+# always_direct deny local-external
+# always_direct allow local-intranet
+# never_direct allow all

+#
+# When adaptation starts, broken services are ignored as if they were

+# WELCOME TO SQUID 3.1.20
+# ----------------------------
+#
+# This is the documentation for the Squid configuration file.
+# This documentation can also be found online at:
+# http://www.squid-cache.org/Doc/config/
+#
+# You may wish to look at the Squid home page and wiki for the
+# FAQ and other documentation:
+# http://www.squid-cache.org/
+# http://wiki.squid-cache.org/SquidFaq
+# http://wiki.squid-cache.org/ConfigExamples
+#
+# This documentation shows what the defaults for various directives
+# happen to be. If you don't need to change the default, you should
+# leave the line out of your squid.conf in most cases.
+#
+# In some cases "none" refers to no default setting at all,
+# while in other cases it refers to the value of the option
+# - the comments for that keyword indicate if this is the case.
+#
+
+# Configuration options can be included using the "include" directive.
+# Include takes a list of files to include. Quoting and wildcards are
+# supported.
+#
+# For example,
+#
+# include /path/to/included/file/squid.acl.config
+#
+# Includes can be nested up to a hard-coded depth of 16 levels.
+# This arbitrary restriction is to prevent recursive include references
+# from causing Squid entering an infinite loop whilst trying to load
+# configuration files.
+
+# TAG: dns_testnames
+# Remove this line. DNS is no longer tested on startup.
+#Default:
+# none
+
+# TAG: extension_methods
+# Remove this line. All valid methods for HTTP are accepted by default.
+#Default:
+# none
+
+# TAG: incoming_rate
+#Default:
+# none
+
+# TAG: server_http11
+# Remove this line. HTTP/1.1 is supported by default.
+#Default:
+# none
+
+# TAG: upgrade_http0.9
+# Remove this line. ICY/1.0 streaming protocol is supported by default.
+#Default:
+# none
+
+# TAG: zph_local
+# Alter these entries. Use the qos_flows directive instead.
+#Default:
+# none
+
+# TAG: header_access
+# Since squid-3.0 replace with request_header_access or reply_header_access
+# depending on whether you wish to match client requests or server replies.
+#Default:
+# none
+
+# TAG: httpd_accel_no_pmtu_disc
+# Since squid-3.0 use the 'disable-pmtu-discovery' flag on http_port instead.
+#Default:
+# none
+
+# OPTIONS FOR AUTHENTICATION
+# -----------------------------------------------------------------------------
+
+# TAG: auth_param
+# This is used to define parameters for the various authentication
+# schemes supported by Squid.
+#
+# format: auth_param scheme parameter [setting]
+#
+# The order in which authentication schemes are presented to the client is
+# dependent on the order the scheme first appears in config file. IE
+# has a bug (it's not RFC 2617 compliant) in that it will use the basic
+# scheme if basic is the first entry presented, even if more secure
+# schemes are presented. For now use the order in the recommended
+# settings section below. If other browsers have difficulties (don't
+# recognize the schemes offered even if you are using basic) either
+# put basic first, or disable the other schemes (by commenting out their
+# program entry).
+#
+# Once an authentication scheme is fully configured, it can only be
+# shutdown by shutting squid down and restarting. Changes can be made on
+# the fly and activated with a reconfigure. I.E. You can change to a
+# different helper, but not unconfigure the helper completely.
+#
+# Please note that while this directive defines how Squid processes
+# authentication it does not automatically activate authentication.
+# To use authentication you must in addition make use of ACLs based
+# on login name in http_access (proxy_auth, proxy_auth_regex or
+# external with %LOGIN used in the format tag). The browser will be
+# challenged for authentication on the first such acl encountered
+# in http_access processing and will also be re-challenged for new
+# login credentials if the request is being denied by a proxy_auth
+# type acl.
+#
+# WARNING: authentication can't be used in a transparently intercepting
+# proxy as the client then thinks it is talking to an origin server and
+# not the proxy. This is a limitation of bending the TCP/IP protocol to
+# transparently intercepting port 80, not a limitation in Squid.
+# Ports flagged 'transparent', 'intercept', or 'tproxy' have
+# authentication disabled.
+#
+# === Parameters for the basic scheme follow. ===
+#
+# "program" cmdline
+# Specify the command for the external authenticator. Such a program
+# reads a line containing "username password" and replies "OK" or
+# "ERR" in an endless loop. "ERR" responses may optionally be followed
+# by a error description available as %m in the returned error page.
+# If you use an authenticator, make sure you have 1 acl of type
+# proxy_auth.
+#
+# By default, the basic authentication scheme is not used unless a
+# program is specified.
+#
+# If you want to use the traditional NCSA proxy authentication, set
+# this line to something like
+#
+# auth_param basic program /usr/lib/squid3/ncsa_auth /usr/etc/passwd
+#
+# "utf8" on|off
+# HTTP uses iso-latin-1 as characterset, while some authentication
+# backends such as LDAP expects UTF-8. If this is set to on Squid will
+# translate the HTTP iso-latin-1 charset to UTF-8 before sending the
+# username & password to the helper.
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn. If you start too few
+# Squid will have to wait for them to process a backlog of credential
+# verifications, slowing it down. When password verifications are
+# done via a (slow) network you are likely to need lots of
+# authenticator processes.
+# auth_param basic children 5
+#
+# "concurrency" concurrency
+# The number of concurrent requests the helper can process.
+# The default of 0 is used for helpers who only supports
+# one request at a time. Setting this changes the protocol used to
+# include a channel number first on the request/response line, allowing
+# multiple requests to be sent to the same helper in parallell without
+# wating for the response.
+# Must not be set unless it's known the helper supports this.
+# auth_param basic concurrency 0
+#
+# "realm" realmstring
+# Specifies the realm name which is to be reported to the
+# client for the basic proxy authentication scheme (part of
+# the text the user will see when prompted their username and
+# password). There is no default.
+# auth_param basic realm Squid proxy-caching web server
+#
+# "credentialsttl" timetolive
+# Specifies how long squid assumes an externally validated
+# username:password pair is valid for - in other words how
+# often the helper program is called for that user. Set this
+# low to force revalidation with short lived passwords. Note
+# setting this high does not impact your susceptibility
+# to replay attacks unless you are using an one-time password
+# system (such as SecureID). If you are using such a system,
+# you will be vulnerable to replay attacks unless you also
+# use the max_user_ip ACL in an http_access rule.
+#
+# "casesensitive" on|off
+# Specifies if usernames are case sensitive. Most user databases are
+# case insensitive allowing the same username to be spelled using both
+# lower and upper case letters, but some are case sensitive. This
+# makes a big difference for user_max_ip ACL processing and similar.
+# auth_param basic casesensitive off
+#
+# === Parameters for the digest scheme follow ===
+#
+# "program" cmdline
+# Specify the command for the external authenticator. Such
+# a program reads a line containing "username":"realm" and
+# replies with the appropriate H(A1) value hex encoded or
+# ERR if the user (or his H(A1) hash) does not exists.
+# See rfc 2616 for the definition of H(A1).
+# "ERR" responses may optionally be followed by a error description
+# available as %m in the returned error page.
+#
+# By default, the digest authentication scheme is not used unless a
+# program is specified.
+#
+# If you want to use a digest authenticator, set this line to
+# something like
+#
+# auth_param digest program /usr/lib/squid3/digest_pw_auth /usr/etc/digpass
+#
+# "utf8" on|off
+# HTTP uses iso-latin-1 as characterset, while some authentication
+# backends such as LDAP expects UTF-8. If this is set to on Squid will
+# translate the HTTP iso-latin-1 charset to UTF-8 before sending the
+# username & password to the helper.
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to
+# process a backlog of H(A1) calculations, slowing it down.
+# When the H(A1) calculations are done via a (slow) network
+# you are likely to need lots of authenticator processes.
+# auth_param digest children 5
+#
+# "realm" realmstring
+# Specifies the realm name which is to be reported to the
+# client for the digest proxy authentication scheme (part of
+# the text the user will see when prompted their username and
+# password). There is no default.
+# auth_param digest realm Squid proxy-caching web server
+#
+# "nonce_garbage_interval" timeinterval
+# Specifies the interval that nonces that have been issued
+# to client_agent's are checked for validity.
+#
+# "nonce_max_duration" timeinterval
+# Specifies the maximum length of time a given nonce will be
+# valid for.
+#
+# "nonce_max_count" number
+# Specifies the maximum number of times a given nonce can be
+# used.
+#
+# "nonce_strictness" on|off
+# Determines if squid requires strict increment-by-1 behavior
+# for nonce counts, or just incrementing (off - for use when
+# useragents generate nonce counts that occasionally miss 1
+# (ie, 1,2,4,6)). Default off.
+#
+# "check_nonce_count" on|off
+# This directive if set to off can disable the nonce count check
+# completely to work around buggy digest qop implementations in
+# certain mainstream browser versions. Default on to check the
+# nonce count to protect from authentication replay attacks.
+#
+# "post_workaround" on|off
+# This is a workaround to certain buggy browsers who sends
+# an incorrect request digest in POST requests when reusing
+# the same nonce as acquired earlier on a GET request.
+#
+# === NTLM scheme options follow ===
+#
+# "program" cmdline
+# Specify the command for the external NTLM authenticator.
+# Such a program reads exchanged NTLMSSP packets with
+# the browser via Squid until authentication is completed.
+# If you use an NTLM authenticator, make sure you have 1 acl
+# of type proxy_auth. By default, the NTLM authenticator_program
+# is not used.
+#
+# auth_param ntlm program /usr/lib/squid3/ntlm_auth
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to
+# process a backlog of credential verifications, slowing it
+# down. When credential verifications are done via a (slow)
+# network you are likely to need lots of authenticator
+# processes.
+#
+# auth_param ntlm children 5
+#
+# "keep_alive" on|off
+# Whether to keep the connection open after the initial response where
+# Squid tells the browser which schemes are supported by the proxy.
+# Some browsers are known to present many login popups or to corrupt
+# POST/PUT requests transfer if the connection is not closed.
+# The default is currently OFF to avoid this, but may change.
+#
+# auth_param ntlm keep_alive on
+#
+# === Options for configuring the NEGOTIATE auth-scheme follow ===
+#
+# "program" cmdline
+# Specify the command for the external Negotiate authenticator.
+# This protocol is used in Microsoft Active-Directory enabled setups with
+# the Microsoft Internet Explorer or Mozilla Firefox browsers.
+# Its main purpose is to exchange credentials with the Squid proxy
+# using the Kerberos mechanisms.
+# If you use a Negotiate authenticator, make sure you have at least
+# one acl of type proxy_auth active. By default, the negotiate
+# authenticator_program is not used.
+# The only supported program for this role is the ntlm_auth
+# program distributed as part of Samba, version 4 or later.
+#
+# auth_param negotiate program /usr/lib/squid3/ntlm_auth --helper-protocol=gss-spnego
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to
+# process a backlog of credential verifications, slowing it
+# down. When crendential verifications are done via a (slow)
+# network you are likely to need lots of authenticator

+# If you use proxy authentication and the 'max_user_ip' ACL,
+# this directive controls how long Squid remembers the IP
+# addresses associated with each user. Use a small value
+# (e.g., 60 seconds) if your users might change addresses
+# quickly, as is the case with dialups. You might be safe

+#
+# Requests may pass through a chain of several other proxies
+# before reaching us. The X-Forwarded-For header will contain a
+# comma-separated list of the IP addresses in the chain, with the
+# rightmost address being the most recent.
+#
+# If a request reaches us from a source that is allowed by this
+# configuration item, then we consult the X-Forwarded-For header
+# to see where that host received the request from. If the
+# X-Forwarded-For header contains multiple addresses, we continue
+# backtracking until we reach an address for which we are not allowed
+# to follow the X-Forwarded-For header, or until we reach the first
+# address in the list. For the purpose of ACL used in the
+# follow_x_forwarded_for directive the src ACL type always matches
+# the address we are testing and srcdomain matches its rDNS.
+#
+# The end result of this process is an IP address that we will
+# refer to as the indirect client address. This address may
+# be treated as the client address for access control, ICAP, delay

+# is too large." If there is no content-length, and the reply

+# an additional ACL needs to be used which ensures the IPv6-bound traffic
+# is never forced or permitted out the IPv4 interface.

+# # This MUST be place before any ALLOW rules.

+# # hostname type port port options

+# cache_peer cdn.example.com sibling 3128 0
+#
+# type: either 'parent', 'sibling', or 'multicast'.
+#
+# proxy-port: The port number where the peer accept HTTP requests.
+# For other Squid proxies this is usually 3128
+# For web servers this is usually 80
+#
+# icp-port: Used for querying neighbor caches about objects.
+# Set to 0 if the peer does not support ICP or HTCP.
+# See ICP and HTCP options below for additional details.
+#
+#
+# ==== ICP OPTIONS ====
+#
+# You MUST also set icp_port and icp_access explicitly when using these options.
+# The defaults will prevent peer traffic using ICP.
+#
+#
+# no-query Disable ICP queries to this neighbor.
+#
+# multicast-responder
+# Indicates the named peer is a member of a multicast group.
+# ICP queries will not be sent directly to the peer, but ICP
+# replies will be accepted from it.
+#
+# closest-only Indicates that, for ICP_OP_MISS replies, we'll only forward
+# CLOSEST_PARENT_MISSes and never FIRST_PARENT_MISSes.
+#
+# background-ping
+# To only send ICP queries to this neighbor infrequently.
+# This is used to keep the neighbor round trip time updated
+# and is usually used in conjunction with weighted-round-robin.
+#
+#
+# ==== HTCP OPTIONS ====
+#
+# You MUST also set htcp_port and htcp_access explicitly when using these options.
+# The defaults will prevent peer traffic using HTCP.
+#
+#
+# htcp Send HTCP, instead of ICP, queries to the neighbor.
+# You probably also want to set the "icp-port" to 4827
+# instead of 3130.
+#
+# htcp-oldsquid Send HTCP to old Squid versions.
+#
+# htcp-no-clr Send HTCP to the neighbor but without
+# sending any CLR requests. This cannot be used with
+# htcp-only-clr.
+#
+# htcp-only-clr Send HTCP to the neighbor but ONLY CLR requests.
+# This cannot be used with htcp-no-clr.
+#
+# htcp-no-purge-clr
+# Send HTCP to the neighbor including CLRs but only when
+# they do not result from PURGE requests.
+#
+# htcp-forward-clr
+# Forward any HTCP CLR requests this proxy receives to the peer.
+#
+#
+# ==== PEER SELECTION METHODS ====
+#
+# The default peer selection method is ICP, with the first responding peer
+# being used as source. These options can be used for better load balancing.
+#
+#
+# default This is a parent cache which can be used as a "last-resort"
+# if a peer cannot be located by any of the peer-selection methods.
+# If specified more than once, only the first is used.
+#
+# round-robin Load-Balance parents which should be used in a round-robin
+# fashion in the absence of any ICP queries.
+# weight=N can be used to add bias.
+#
+# weighted-round-robin
+# Load-Balance parents which should be used in a round-robin
+# fashion with the frequency of each parent being based on the
+# round trip time. Closer parents are used more often.
+# Usually used for background-ping parents.
+# weight=N can be used to add bias.
+#
+# carp Load-Balance parents which should be used as a CARP array.
+# The requests will be distributed among the parents based on the
+# CARP load balancing hash function based on their weight.
+#
+# userhash Load-balance parents based on the client proxy_auth or ident username.
+#
+# sourcehash Load-balance parents based on the client source IP.
+#
+# multicast-siblings
+# To be used only for cache peers of type "multicast".
+# ALL members of this multicast group have "sibling"
+# relationship with it, not "parent". This is to a multicast
+# group when the requested object would be fetched only from
+# a "parent" cache, anyway. It's useful, e.g., when
+# configuring a pool of redundant Squid proxies, being
+# members of the same multicast group.
+#
+#
+# ==== PEER SELECTION OPTIONS ====
+#
+# weight=N use to affect the selection of a peer during any weighted
+# peer-selection mechanisms.
+# The weight must be an integer; default is 1,
+# larger weights are favored more.
+# This option does not affect parent selection if a peering
+# protocol is not in use.
+#
+# basetime=N Specify a base amount to be subtracted from round trip
+# times of parents.
+# It is subtracted before division by weight in calculating
+# which parent to fectch from. If the rtt is less than the
+# base time the rtt is set to a minimal value.
+#
+# ttl=N Specify a TTL to use when sending multicast ICP queries
+# to this address.
+# Only useful when sending to a multicast group.
+# Because we don't accept ICP replies from random
+# hosts, you must configure other group members as
+# peers with the 'multicast-responder' option.
+#
+# no-delay To prevent access to this neighbor from influencing the
+# delay pools.
+#
+# digest-url=URL Tell Squid to fetch the cache digest (if digests are
+# enabled) for this host from the specified URL rather
+# than the Squid default location.
+#
+#
+# ==== ACCELERATOR / REVERSE-PROXY OPTIONS ====
+#
+# originserver Causes this parent to be contacted as an origin server.
+# Meant to be used in accelerator setups when the peer
+# is a web server.
+#
+# forceddomain=name
+# Set the Host header of requests forwarded to this peer.
+# Useful in accelerator setups where the server (peer)
+# expects a certain domain name but clients may request
+# others. ie example.com or www.example.com
+#
+# no-digest Disable request of cache digests.
+#
+# no-netdb-exchange
+# Disables requesting ICMP RTT database (NetDB).
+#
+#
+# ==== AUTHENTICATION OPTIONS ====
+#
+# login=user:password
+# If this is a personal/workgroup proxy and your parent
+# requires proxy authentication.
+#
+# Note: The string can include URL escapes (i.e. %20 for
+# spaces). This also means % must be written as %%.
+#
+# login=PROXYPASS
+# Send login details received from client to this peer.
+# Authentication is not required, nor changed.
+#
+# Note: This will pass any form of authentication but
+# only Basic auth will work through a proxy unless the
+# connection-auth options are also used.
+#
+# login=PASS Send login details received from client to this peer.
+# Authentication is not required by this option.
+# If there are no client-provided authentication headers
+# to pass on, but username and password are available
+# from either proxy login or an external ACL user= and
+# password= result tags they may be sent instead.
+#
+# Note: To combine this with proxy_auth both proxies must
+# share the same user database as HTTP only allows for
+# a single login (one for proxy, one for origin server).
+# Also be warned this will expose your users proxy
+# password to the peer. USE WITH CAUTION
+#
+# login=*:password
+# Send the username to the upstream cache, but with a
+# fixed password. This is meant to be used when the peer
+# is in another administrative domain, but it is still
+# needed to identify each user.
+# The star can optionally be followed by some extra
+# information which is added to the username. This can
+# be used to identify this proxy to the peer, similar to
+# the login=username:password option above.
+#
+# connection-auth=on|off
+# Tell Squid that this peer does or not support Microsoft
+# connection oriented authentication, and any such
+# challenges received from there should be ignored.
+# Default is auto to automatically determine the status
+# of the peer.
+#
+#
+# ==== SSL / HTTPS / TLS OPTIONS ====
+#
+# ssl Encrypt connections to this peer with SSL/TLS.
+#
+# sslcert=/path/to/ssl/certificate
+# A client SSL certificate to use when connecting to
+# this peer.
+#
+# sslkey=/path/to/ssl/key
+# The private SSL key corresponding to sslcert above.
+# If 'sslkey' is not specified 'sslcert' is assumed to
+# reference a combined file containing both the
+# certificate and the key.
+#
+# sslversion=1|2|3|4
+# The SSL version to use when connecting to this peer
+# 1 = automatic (default)
+# 2 = SSL v2 only
+# 3 = SSL v3 only
+# 4 = TLS v1 only
+#
+# sslcipher=... The list of valid SSL ciphers to use when connecting
+# to this peer.
+#
+# ssloptions=... Specify various SSL engine options:
+# NO_SSLv2 Disallow the use of SSLv2
+# NO_SSLv3 Disallow the use of SSLv3
+# NO_TLSv1 Disallow the use of TLSv1
+# See src/ssl_support.c or the OpenSSL documentation for
+# a more complete list.
+#
+# sslcafile=... A file containing additional CA certificates to use
+# when verifying the peer certificate.
+#
+# sslcapath=... A directory containing additional CA certificates to
+# use when verifying the peer certificate.
+#
+# sslcrlfile=... A certificate revocation list file to use when
+# verifying the peer certificate.
+#
+# sslflags=... Specify various flags modifying the SSL implementation:
+#
+# DONT_VERIFY_PEER
+# Accept certificates even if they fail to
+# verify.
+# NO_DEFAULT_CA
+# Don't use the default CA list built in
+# to OpenSSL.
+# DONT_VERIFY_DOMAIN
+# Don't verify the peer certificate
+# matches the server name
+#
+# ssldomain= The peer name as advertised in it's certificate.
+# Used for verifying the correctness of the received peer
+# certificate. If not specified the peer hostname will be
+# used.
+#
+# front-end-https
+# Enable the "Front-End-Https: On" header needed when
+# using Squid as a SSL frontend in front of Microsoft OWA.
+# See MS KB document Q307347 for details on this header.
+# If set to auto the header will only be added if the
+# request is forwarded as a https:// URL.
+#
+#
+# ==== GENERAL OPTIONS ====
+#
+# connect-timeout=N
+# A peer-specific connect timeout.
+# Also see the peer_connect_timeout directive.
+#
+# connect-fail-limit=N
+# How many times connecting to a peer must fail before
+# it is marked as down. Default is 10.
+#
+# allow-miss Disable Squid's use of only-if-cached when forwarding
+# requests to siblings. This is primarily useful when
+# icp_hit_stale is used by the sibling. To extensive use
+# of this option may result in forwarding loops, and you
+# should avoid having two-way peerings with this option.
+# For example to deny peer usage on requests from peer
+# by denying cache_peer_access if the source is a peer.
+#
+# max-conn=N Limit the amount of connections Squid may open to this
+# peer. see also
+#
+# name=xxx Unique name for the peer.
+# Required if you have multiple peers on the same host
+# but different ports.
+# This name can be used in cache_peer_access and similar
+# directives to dentify the peer.
+# Can be used by outgoing access controls through the
+# peername ACL type.
+#
+# no-tproxy Do not use the client-spoof TPROXY support when forwarding
+# requests to this peer. Use normal address selection instead.
+#
+# proxy-only objects fetched from the peer will not be stored locally.
+#
+#Default:
+# none
+
+# TAG: cache_peer_domain
+# Use to limit the domains for which a neighbor cache will be
+# queried. Usage:
+#
+# cache_peer_domain cache-host domain [domain ...]
+# cache_peer_domain cache-host !domain
+#
+# For example, specifying
+#
+# cache_peer_domain parent.foo.net .edu
+#
+# has the effect such that UDP query packets are sent to
+# 'bigserver' only when the requested object exists on a
+# server in the .edu domain. Prefixing the domainname
+# with '!' means the cache will be queried for objects
+# NOT in that domain.
+#
+# NOTE: * Any number of domains may be given for a cache-host,
+# either on the same or separate lines.
+# * When multiple domains are given for a particular
+# cache-host, the first matched domain is applied.
+# * Cache hosts with no domain restrictions are queried
+# for all requests.
+# * There are no defaults.
+# * There is also a 'cache_peer_access' tag in the ACL
+# section.
+#Default:
+# none
+
+# TAG: cache_peer_access
+# Similar to 'cache_peer_domain' but provides more flexibility by
+# using ACL elements.
+#
+# cache_peer_access cache-host allow|deny [!]aclname ...
+#
+# The syntax is identical to 'http_access' and the other lists of
+# ACL elements. See the comments for 'http_access' below, or
+# the Squid FAQ (http://wiki.squid-cache.org/SquidFaq/SquidAcl).
+#Default:
+# none
+
+# TAG: neighbor_type_domain
+# usage: neighbor_type_domain neighbor parent|sibling domain domain ...
+#
+# Modifying the neighbor type for specific domains is now
+# possible. You can treat some domains differently than the the
+# default neighbor type specified on the 'cache_peer' line.
+# Normally it should only be necessary to list domains which
+# should be treated differently because the default neighbor type
+# applies for hostnames which do not match domains listed here.
+#
+#EXAMPLE:
+# cache_peer cache.foo.org parent 3128 3130
+# neighbor_type_domain cache.foo.org sibling .com .net
+# neighbor_type_domain cache.foo.org sibling .au .de
+#Default:
+# none
+
+# TAG: dead_peer_timeout (seconds)
+# This controls how long Squid waits to declare a peer cache
+# as "dead." If there are no ICP replies received in this
+# amount of time, Squid will declare the peer dead and not
+# expect to receive any further ICP replies. However, it
+# continues to send ICP queries, and will mark the peer as
+# alive upon receipt of the first subsequent ICP reply.
+#
+# This timeout also affects when Squid expects to receive ICP
+# replies from peers. If more than 'dead_peer' seconds have
+# passed since the last ICP reply was received, Squid will not
+# expect to receive an ICP reply on the next query. Thus, if
+# your time between requests is greater than this timeout, you
+# will see a lot of requests sent DIRECT to origin servers
+# instead of to your parents.
+#Default:
+# dead_peer_timeout 10 seconds
+
+# TAG: forward_max_tries
+# Controls how many different forward paths Squid will try
+# before giving up. See also forward_timeout.
+#Default:
+# forward_max_tries 10
+
+# TAG: hierarchy_stoplist
+# A list of words which, if found in a URL, cause the object to
+# be handled directly by this cache. In other words, use this
+# to not query neighbor caches for certain objects. You may
+# list this option multiple times.
+#
+# Example:
+# hierarchy_stoplist cgi-bin ?
+#
+# Note: never_direct overrides this option.
+#Default:
+# none
+
+# MEMORY CACHE OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: cache_mem (bytes)
+# NOTE: THIS PARAMETER DOES NOT SPECIFY THE MAXIMUM PROCESS SIZE.
+# IT ONLY PLACES A LIMIT ON HOW MUCH ADDITIONAL MEMORY SQUID WILL
+# USE AS A MEMORY CACHE OF OBJECTS. SQUID USES MEMORY FOR OTHER
+# THINGS AS WELL. SEE THE SQUID FAQ SECTION 8 FOR DETAILS.
+#
+# 'cache_mem' specifies the ideal amount of memory to be used
+# for:
+# * In-Transit objects
+# * Hot Objects
+# * Negative-Cached objects
+#
+# Data for these objects are stored in 4 KB blocks. This
+# parameter specifies the ideal upper limit on the total size of
+# 4 KB blocks allocated. In-Transit objects take the highest
+# priority.
+#
+# In-transit objects have priority over the others. When
+# additional space is needed for incoming data, negative-cached
+# and hot objects will be released. In other words, the
+# negative-cached and hot objects will fill up any unused space
+# not needed for in-transit objects.
+#
+# If circumstances require, this limit will be exceeded.
+# Specifically, if your incoming request rate requires more than
+# 'cache_mem' of memory to hold in-transit objects, Squid will
+# exceed this limit to satisfy the new requests. When the load
+# decreases, blocks will be freed until the high-water mark is
+# reached. Thereafter, blocks will be used to store hot
+# objects.
+#Default:
+# cache_mem 256 MB
+
+# TAG: maximum_object_size_in_memory (bytes)
+# Objects greater than this size will not be attempted to kept in
+# the memory cache. This should be set high enough to keep objects
+# accessed frequently in memory to improve performance whilst low
+# enough to keep larger objects from hoarding cache_mem.
+#Default:
+# maximum_object_size_in_memory 512 KB
+
+# TAG: memory_replacement_policy
+# The memory replacement policy parameter determines which
+# objects are purged from memory when memory space is needed.
+#
+# See cache_replacement_policy for details.
+#Default:
+# memory_replacement_policy lru
+
+# DISK CACHE OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: cache_replacement_policy
+# The cache replacement policy parameter determines which
+# objects are evicted (replaced) when disk space is needed.
+#
+# lru : Squid's original list based LRU policy
+# heap GDSF : Greedy-Dual Size Frequency
+# heap LFUDA: Least Frequently Used with Dynamic Aging
+# heap LRU : LRU policy implemented using a heap
+#
+# Applies to any cache_dir lines listed below this.
+#
+# The LRU policies keeps recently referenced objects.
+#
+# The heap GDSF policy optimizes object hit rate by keeping smaller
+# popular objects in cache so it has a better chance of getting a
+# hit. It achieves a lower byte hit rate than LFUDA though since
+# it evicts larger (possibly popular) objects.
+#
+# The heap LFUDA policy keeps popular objects in cache regardless of
+# their size and thus optimizes byte hit rate at the expense of
+# hit rate since one large, popular object will prevent many
+# smaller, slightly less popular objects from being cached.
+#
+# Both policies utilize a dynamic aging mechanism that prevents
+# cache pollution that can otherwise occur with frequency-based
+# replacement policies.
+#
+# NOTE: if using the LFUDA replacement policy you should increase
+# the value of maximum_object_size above its default of 4096 KB to
+# to maximize the potential byte hit rate improvement of LFUDA.
+#
+# For more information about the GDSF and LFUDA cache replacement

+# TAG: cache_dir
+# Usage:
+#
+# cache_dir Type Directory-Name Fs-specific-data [options]
+#
+# You can specify multiple cache_dir lines to spread the
+# cache among different disk partitions.
+#
+# Type specifies the kind of storage system to use. Only "ufs"
+# is built by default. To enable any of the other storage systems
+# see the --enable-storeio configure option.
+#
+# 'Directory' is a top-level directory where cache swap
+# files will be stored. If you want to use an entire disk
+# for caching, this can be the mount-point directory.
+# The directory must exist and be writable by the Squid
+# process. Squid will NOT create this directory for you.
+#
+# The ufs store type:
+#
+# "ufs" is the old well-known Squid storage format that has always
+# been there.
+#
+# cache_dir ufs Directory-Name Mbytes L1 L2 [options]
+#
+# 'Mbytes' is the amount of disk space (MB) to use under this
+# directory. The default is 100 MB. Change this to suit your
+# configuration. Do NOT put the size of your disk drive here.
+# Instead, if you want Squid to use the entire disk drive,
+# subtract 20% and use that value.
+#
+# 'L1' is the number of first-level subdirectories which
+# will be created under the 'Directory'. The default is 16.
+#
+# 'L2' is the number of second-level subdirectories which
+# will be created under each first-level directory. The default
+# is 256.
+#
+# The aufs store type:
+#
+# "aufs" uses the same storage format as "ufs", utilizing
+# POSIX-threads to avoid blocking the main Squid process on
+# disk-I/O. This was formerly known in Squid as async-io.
+#
+# cache_dir aufs Directory-Name Mbytes L1 L2 [options]
+#
+# see argument descriptions under ufs above
+#
+# The diskd store type:
+#
+# "diskd" uses the same storage format as "ufs", utilizing a
+# separate process to avoid blocking the main Squid process on
+# disk-I/O.
+#
+# cache_dir diskd Directory-Name Mbytes L1 L2 [options] [Q1=n] [Q2=n]
+#
+# see argument descriptions under ufs above
+#
+# Q1 specifies the number of unacknowledged I/O requests when Squid
+# stops opening new files. If this many messages are in the queues,
+# Squid won't open new files. Default is 64
+#
+# Q2 specifies the number of unacknowledged messages when Squid
+# starts blocking. If this many messages are in the queues,
+# Squid blocks until it receives some replies. Default is 72
+#
+# When Q1 < Q2 (the default), the cache directory is optimized
+# for lower response time at the expense of a decrease in hit
+# ratio. If Q1 > Q2, the cache directory is optimized for
+# higher hit ratio at the expense of an increase in response
+# time.
+#
+# The coss store type:
+#
+# NP: COSS filesystem in Squid-3 has been deemed too unstable for
+# production use and has thus been removed from this release.
+# We hope that it can be made usable again soon.
+#
+# block-size=n defines the "block size" for COSS cache_dir's.
+# Squid uses file numbers as block numbers. Since file numbers
+# are limited to 24 bits, the block size determines the maximum
+# size of the COSS partition. The default is 512 bytes, which
+# leads to a maximum cache_dir size of 512<<24, or 8 GB. Note
+# you should not change the coss block size after Squid
+# has written some objects to the cache_dir.
+#
+# The coss file store has changed from 2.5. Now it uses a file
+# called 'stripe' in the directory names in the config - and
+# this will be created by squid -z.
+#
+# Common options:
+#
+# no-store, no new objects should be stored to this cache_dir
+#
+# max-size=n, refers to the max object size in bytes this cache_dir
+# supports. It is used to select the cache_dir to store the object.
+# Note: To make optimal use of the max-size limits you should order
+# the cache_dir lines with the smallest max-size value first and the
+# ones with no max-size specification last.
+#
+# Note for coss, max-size must be less than COSS_MEMBUF_SZ,
+# which can be changed with the --with-coss-membuf-size=N configure
+# option.

+# ICAP log files record ICAP transaction summaries, one line per
+# transaction.
+#
+# The icap_log option format is:
+# icap_log <filepath> [<logformat name> [acl acl ...]]
+# icap_log none [acl acl ...]]
+#
+# Please see access_log option documentation for details. The two
+# kinds of logs share the overall configuration approach and many
+# features.
+#
+# ICAP processing of a single HTTP message or transaction may
+# require multiple ICAP transactions. In such cases, multiple
+# ICAP transaction log lines will correspond to a single access
+# log line.
+#
+# ICAP log uses logformat codes that make sense for an ICAP
+# transaction. Header-related codes are applied to the HTTP header
+# embedded in an ICAP server response, with the following caveats:
+# For REQMOD, there is no HTTP response header unless the ICAP
+# server performed request satisfaction. For RESPMOD, the HTTP
+# request header is the header sent to the ICAP server. For
+# OPTIONS, there are no HTTP headers.
+#
+# The following format codes are also available for ICAP logs:
+#
+# icap::<A ICAP server IP address. Similar to <A.
+#
+# icap::<service_name ICAP service name from the icap_service
+# option in Squid configuration file.
+#
+# icap::ru ICAP Request-URI. Similar to ru.
+#
+# icap::rm ICAP request method (REQMOD, RESPMOD, or
+# OPTIONS). Similar to existing rm.
+#
+# icap::>st Bytes sent to the ICAP server (TCP payload
+# only; i.e., what Squid writes to the socket).
+#
+# icap::<st Bytes received from the ICAP server (TCP
+# payload only; i.e., what Squid reads from
+# the socket).
+#
+# icap::tr Transaction response time (in
+# milliseconds). The timer starts when
+# the ICAP transaction is created and
+# stops when the transaction is completed.
+# Similar to tr.
+#
+# icap::tio Transaction I/O time (in milliseconds). The
+# timer starts when the first ICAP request
+# byte is scheduled for sending. The timers
+# stops when the last byte of the ICAP response
+# is received.
+#
+# icap::to Transaction outcome: ICAP_ERR* for all
+# transaction errors, ICAP_OPT for OPTION
+# transactions, ICAP_ECHO for 204
+# responses, ICAP_MOD for message
+# modification, and ICAP_SAT for request
+# satisfaction. Similar to Ss.
+#
+# icap::Hs ICAP response status code. Similar to Hs.
+#
+# icap::>h ICAP request header(s). Similar to >h.
+#
+# icap::<h ICAP response header(s). Similar to <h.
+#
+# The default ICAP log format, which can be used without an explicit

+
+# TAG: cache_swap_state
+# Location for the cache "swap.state" file. This index file holds
+# the metadata of objects saved on disk. It is used to rebuild
+# the cache during startup. Normally this file resides in each
+# 'cache_dir' directory, but you may specify an alternate
+# pathname here. Note you must give a full filename, not just
+# a directory. Since this is the index for the whole object
+# list you CANNOT periodically rotate it!
+#
+# If %s can be used in the file name it will be replaced with a
+# a representation of the cache_dir name where each / is replaced
+# with '.'. This is needed to allow adding/removing cache_dir

+# disable the file name rotation, but the logfiles are still closed
+# and re-opened. This will enable you to rename the logfiles
+# yourself just before sending the rotate signal.
+#
+# Note, the 'squid -k rotate' command normally sends a USR1
+# signal to the running squid process. In certain situations
+# (e.g. on Linux with Async I/O), USR1 is used for other
+# purposes, so -k rotate uses another signal. It is best to get
+# in the habit of using 'squid -k rotate' instead of 'kill -USR1
+# <pid>'.
+#
+# Note, from Squid-3.1 this option has no effect on the cache.log,

+# of 5.5 is unchanged from old versions of Squid (i.e. a
+# forced refresh is impossible). Newer versions of IE will,

+# DELAY POOL PARAMETERS
+# -----------------------------------------------------------------------------
+
+# TAG: delay_pools
+# This represents the number of delay pools to be used. For example,
+# if you have one class 2 delay pool and one class 3 delays pool, you
+# have a total of 2 delay pools.
+#Default:
+# delay_pools 0
+
+# TAG: delay_class
+# This defines the class of each delay pool. There must be exactly one
+# delay_class line for each delay pool. For example, to define two
+# delay pools, one of class 2 and one of class 3, the settings above
+# and here would be:
+#
+# Example:
+# delay_pools 4 # 4 delay pools
+# delay_class 1 2 # pool 1 is a class 2 pool
+# delay_class 2 3 # pool 2 is a class 3 pool
+# delay_class 3 4 # pool 3 is a class 4 pool
+# delay_class 4 5 # pool 4 is a class 5 pool
+#
+# The delay pool classes are:
+#
+# class 1 Everything is limited by a single aggregate
+# bucket.
+#
+# class 2 Everything is limited by a single aggregate
+# bucket as well as an "individual" bucket chosen
+# from bits 25 through 32 of the IPv4 address.
+#
+# class 3 Everything is limited by a single aggregate
+# bucket as well as a "network" bucket chosen
+# from bits 17 through 24 of the IP address and a
+# "individual" bucket chosen from bits 17 through
+# 32 of the IPv4 address.
+#
+# class 4 Everything in a class 3 delay pool, with an
+# additional limit on a per user basis. This
+# only takes effect if the username is established
+# in advance - by forcing authentication in your
+# http_access rules.
+#
+# class 5 Requests are grouped according their tag (see
+# external_acl's tag= reply).
+#
+#
+# Each pool also requires a delay_parameters directive to configure the pool size
+# and speed limits used whenever the pool is applied to a request. Along with
+# a set of delay_access directives to determine when it is used.
+#
+# NOTE: If an IP address is a.b.c.d
+# -> bits 25 through 32 are "d"
+# -> bits 17 through 24 are "c"
+# -> bits 17 through 32 are "c * 256 + d"
+#
+# NOTE-2: Due to the use of bitmasks in class 2,3,4 pools they only apply to
+# IPv4 traffic. Class 1 and 5 pools may be used with IPv6 traffic.
+#Default:
+# none
+
+# TAG: delay_access
+# This is used to determine which delay pool a request falls into.
+#
+# delay_access is sorted per pool and the matching starts with pool 1,
+# then pool 2, ..., and finally pool N. The first delay pool where the
+# request is allowed is selected for the request. If it does not allow
+# the request to any pool then the request is not delayed (default).
+#
+# For example, if you want some_big_clients in delay
+# pool 1 and lotsa_little_clients in delay pool 2:
+#
+#Example:
+# delay_access 1 allow some_big_clients
+# delay_access 1 deny all
+# delay_access 2 allow lotsa_little_clients
+# delay_access 2 deny all
+# delay_access 3 allow authenticated_clients
+#Default:
+# none
+
+# TAG: delay_parameters
+# This defines the parameters for a delay pool. Each delay pool has
+# a number of "buckets" associated with it, as explained in the
+# description of delay_class.
+#
+# For a class 1 delay pool, the syntax is:
+# delay_pools pool 1
+# delay_parameters pool aggregate
+#
+# For a class 2 delay pool:
+# delay_pools pool 2
+# delay_parameters pool aggregate individual
+#
+# For a class 3 delay pool:
+# delay_pools pool 3
+# delay_parameters pool aggregate network individual
+#
+# For a class 4 delay pool:
+# delay_pools pool 4
+# delay_parameters pool aggregate network individual user
+#
+# For a class 5 delay pool:
+# delay_pools pool 5
+# delay_parameters pool tagrate
+#
+# The option variables are:
+#
+# pool a pool number - ie, a number between 1 and the
+# number specified in delay_pools as used in
+# delay_class lines.
+#
+# aggregate the speed limit parameters for the aggregate bucket
+# (class 1, 2, 3).
+#
+# individual the speed limit parameters for the individual
+# buckets (class 2, 3).
+#
+# network the speed limit parameters for the network buckets
+# (class 3).
+#
+# user the speed limit parameters for the user buckets
+# (class 4).
+#
+# tagrate the speed limit parameters for the tag buckets
+# (class 5).
+#
+# A pair of delay parameters is written restore/maximum, where restore is
+# the number of bytes (not bits - modem and network speeds are usually
+# quoted in bits) per second placed into the bucket, and maximum is the
+# maximum number of bytes which can be in the bucket at any time.
+#
+# There must be one delay_parameters line for each delay pool.
+#
+#
+# For example, if delay pool number 1 is a class 2 delay pool as in the
+# above example, and is being used to strictly limit each host to 64Kbit/sec
+# (plus overheads), with no overall limit, the line is:
+#
+# delay_parameters 1 -1/-1 8000/8000
+#
+# Note that 8 x 8000 KByte/sec -> 64Kbit/sec.
+#
+# Note that the figure -1 is used to represent "unlimited".
+#
+#
+# And, if delay pool number 2 is a class 3 delay pool as in the above
+# example, and you want to limit it to a total of 256Kbit/sec (strict limit)
+# with each 8-bit network permitted 64Kbit/sec (strict limit) and each
+# individual host permitted 4800bit/sec with a bucket maximum size of 64Kbits
+# to permit a decent web page to be downloaded at a decent speed
+# (if the network is not being limited due to overuse) but slow down
+# large downloads more significantly:
+#
+# delay_parameters 2 32000/32000 8000/8000 600/8000
+#
+# Note that 8 x 32000 KByte/sec -> 256Kbit/sec.
+# 8 x 8000 KByte/sec -> 64Kbit/sec.
+# 8 x 600 Byte/sec -> 4800bit/sec.
+#
+#
+# Finally, for a class 4 delay pool as in the example - each user will
+# be limited to 128Kbits/sec no matter how many workstations they are logged into.:
+#
+# delay_parameters 4 32000/32000 8000/8000 600/64000 16000/16000
+#Default:
+# none
+
+# TAG: delay_initial_bucket_level (percent, 0-100)
+# The initial bucket percentage is used to determine how much is put
+# in each bucket when squid starts, is reconfigured, or first notices
+# a host accessing it (in class 2 and class 3, individual hosts and
+# networks only have buckets associated with them once they have been
+# "seen" by squid).
+#Default:
+# delay_initial_bucket_level 50
+
+# WCCPv1 AND WCCPv2 CONFIGURATION OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: wccp_router
+# Use this option to define your WCCP ``home'' router for
+# Squid.
+#
+# wccp_router supports a single WCCP(v1) router
+#
+# wccp2_router supports multiple WCCPv2 routers
+#
+# only one of the two may be used at the same time and defines
+# which version of WCCP to use.
+#Default:

+
+# TAG: wccp2_router
+# Use this option to define your WCCP ``home'' router for
+# Squid.
+#
+# wccp_router supports a single WCCP(v1) router
+#
+# wccp2_router supports multiple WCCPv2 routers
+#
+# only one of the two may be used at the same time and defines

+#Default:
+# none
+
+# TAG: wccp_version
+# This directive is only relevant if you need to set up WCCP(v1)
+# to some very old and end-of-life Cisco routers. In all other
+# setups it must be left unset or at the default setting.
+# It defines an internal version in the WCCP(v1) protocol,
+# with version 4 being the officially documented protocol.
+#
+# According to some users, Cisco IOS 11.2 and earlier only
+# support WCCP version 3. If you're using that or an earlier
+# version of IOS, you may need to change this value to 3, otherwise
+# do not specify this parameter.
+#Default:
+# wccp_version 4
+
+# TAG: wccp2_rebuild_wait
+# If this is enabled Squid will wait for the cache dir rebuild to finish
+# before sending the first wccp2 HereIAm packet
+#Default:
+# wccp2_rebuild_wait on
+
+# TAG: wccp2_forwarding_method
+# WCCP2 allows the setting of forwarding methods between the
+# router/switch and the cache. Valid values are as follows:
+#
+# gre - GRE encapsulation (forward the packet in a GRE/WCCP tunnel)
+# l2 - L2 redirect (forward the packet using Layer 2/MAC rewriting)
+#
+# Currently (as of IOS 12.4) cisco routers only support GRE.
+# Cisco switches only support the L2 redirect assignment method.
+#Default:
+# wccp2_forwarding_method gre
+
+# TAG: wccp2_return_method
+# WCCP2 allows the setting of return methods between the
+# router/switch and the cache for packets that the cache
+# decides not to handle. Valid values are as follows:
+#
+# gre - GRE encapsulation (forward the packet in a GRE/WCCP tunnel)
+# l2 - L2 redirect (forward the packet using Layer 2/MAC rewriting)
+#
+# Currently (as of IOS 12.4) cisco routers only support GRE.
+# Cisco switches only support the L2 redirect assignment.
+#
+# If the "ip wccp redirect exclude in" command has been
+# enabled on the cache interface, then it is still safe for
+# the proxy server to use a l2 redirect method even if this
+# option is set to GRE.
+#Default:
+# wccp2_return_method gre
+
+# TAG: wccp2_assignment_method
+# WCCP2 allows the setting of methods to assign the WCCP hash
+# Valid values are as follows:
+#
+# hash - Hash assignment
+# mask - Mask assignment
+#
+# As a general rule, cisco routers support the hash assignment method
+# and cisco switches support the mask assignment method.
+#Default:
+# wccp2_assignment_method hash
+
+# TAG: wccp2_service
+# WCCP2 allows for multiple traffic services. There are two
+# types: "standard" and "dynamic". The standard type defines
+# one service id - http (id 0). The dynamic service ids can be from
+# 51 to 255 inclusive. In order to use a dynamic service id
+# one must define the type of traffic to be redirected; this is done
+# using the wccp2_service_info option.
+#
+# The "standard" type does not require a wccp2_service_info option,
+# just specifying the service id will suffice.
+#
+# MD5 service authentication can be enabled by adding
+# "password=<password>" to the end of this service declaration.
+#
+# Examples:
+#
+# wccp2_service standard 0 # for the 'web-cache' standard service
+# wccp2_service dynamic 80 # a dynamic service type which will be
+# # fleshed out with subsequent options.
+# wccp2_service standard 0 password=foo
+#Default:
+# wccp2_service standard 0
+
+# TAG: wccp2_service_info
+# Dynamic WCCPv2 services require further information to define the
+# traffic you wish to have diverted.
+#
+# The format is:
+#
+# wccp2_service_info <id> protocol=<protocol> flags=<flag>,<flag>..
+# priority=<priority> ports=<port>,<port>..
+#
+# The relevant WCCPv2 flags:
+# + src_ip_hash, dst_ip_hash
+# + source_port_hash, dst_port_hash
+# + src_ip_alt_hash, dst_ip_alt_hash
+# + src_port_alt_hash, dst_port_alt_hash
+# + ports_source
+#
+# The port list can be one to eight entries.
+#
+# Example:
+#
+# wccp2_service_info 80 protocol=tcp flags=src_ip_hash,ports_source
+# priority=240 ports=80
+#
+# Note: the service id must have been defined by a previous
+# 'wccp2_service dynamic <id>' entry.
+#Default:
+# none
+
+# TAG: wccp2_weight
+# Each cache server gets assigned a set of the destination
+# hash proportional to their weight.
+#Default:
+# wccp2_weight 10000
+
+# TAG: wccp_address
+#Default:
+# wccp_address 0.0.0.0
+
+# TAG: wccp2_address
+# Use this option if you require WCCP to use a specific
+# interface address.
+#
+# The default behavior is to not bind to any specific address.
+#Default:
+# wccp2_address 0.0.0.0
+
+# PERSISTENT CONNECTION HANDLING
+# -----------------------------------------------------------------------------
+#
+# Also see "pconn_timeout" in the TIMEOUTS section
+
+# TAG: client_persistent_connections
+#Default:
+# client_persistent_connections on
+
+# TAG: server_persistent_connections
+# Persistent connection support for clients and servers. By
+# default, Squid uses persistent connections (when allowed)
+# with its clients and servers. You can use these options to
+# disable persistent connections with clients and/or servers.
+#Default:
+# server_persistent_connections on
+
+# TAG: persistent_connection_after_error
+# With this directive the use of persistent connections after
+# HTTP errors can be disabled. Useful if you have clients
+# who fail to handle errors on persistent connections proper.
+#Default:
+# persistent_connection_after_error on
+
+# TAG: detect_broken_pconn
+# Some servers have been found to incorrectly signal the use
+# of HTTP/1.0 persistent connections even on replies not
+# compatible, causing significant delays. This server problem
+# has mostly been seen on redirects.
+#
+# By enabling this directive Squid attempts to detect such
+# broken replies and automatically assume the reply is finished
+# after 10 seconds timeout.
+#Default:
+# detect_broken_pconn off
+
+# CACHE DIGEST OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: digest_generation
+# This controls whether the server will generate a Cache Digest
+# of its contents. By default, Cache Digest generation is
+# enabled if Squid is compiled with --enable-cache-digests defined.
+#Default:
+# digest_generation on
+
+# TAG: digest_bits_per_entry
+# This is the number of bits of the server's Cache Digest which

+#Default:
+# digest_rewrite_period 1 hour
+
+# TAG: digest_swapout_chunk_size (bytes)
+# This is the number of bytes of the Cache Digest to write to

+# default swap page.
+#Default:
+# digest_swapout_chunk_size 4096 bytes
+
+# TAG: digest_rebuild_chunk_percentage (percent, 0-100)
+# This is the percentage of the Cache Digest to be scanned at a

+
+# SNMP OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: snmp_port
+# The port number where Squid listens for SNMP requests. To enable
+# SNMP support set this to a suitable port number. Port number
+# 3401 is often used for the Squid SNMP agent. By default it's
+# set to "0" (disabled)
+#
+# Example:
+# snmp_port 3401
+#Default:
+# snmp_port 0
+
+# TAG: snmp_access
+# Allowing or denying access to the SNMP port.
+#
+# All access to the agent is denied by default.
+# usage:
+#
+# snmp_access allow|deny [!]aclname ...
+#
+# This clause only supports fast acl types.
+# See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.

+# TAG: snmp_incoming_address
+#Default:
+# snmp_incoming_address any_addr
+
+# TAG: snmp_outgoing_address
+# Just like 'udp_incoming_address', but for the SNMP port.
+#
+# snmp_incoming_address is used for the SNMP socket receiving
+# messages from SNMP agents.
+# snmp_outgoing_address is used for SNMP packets returned to SNMP
+# agents.
+#
+# The default snmp_incoming_address is to listen on all
+# available network interfaces.
+#
+# If snmp_outgoing_address is not set it will use the same socket
+# as snmp_incoming_address. Only change this if you want to have
+# SNMP replies sent using another address than where this Squid
+# listens for SNMP queries.
+#
+# NOTE, snmp_incoming_address and snmp_outgoing_address can not have

+
+# ICP OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: icp_port
+# The port number where Squid sends and receives ICP queries to

+#Default:
+# icp_port 0
+
+# TAG: htcp_port
+# The port number where Squid sends and receives HTCP queries to

+# Example:
+# htcp_port 4827
+#Default:
+# htcp_port 0
+
+# TAG: log_icp_queries on|off

+#
+# The default behavior is to not bind to any specific address.
+#
+# Only change this if you want to have all UDP queries received on

+# OPTIONS INFLUENCING REQUEST FORWARDING
+# -----------------------------------------------------------------------------
+
+# TAG: nonhierarchical_direct
+# By default, Squid will send any non-hierarchical requests
+# (matching hierarchy_stoplist or not cacheable request type) direct
+# to origin servers.
+#
+# If you set this to off, Squid will prefer to send these
+# requests to parents.
+#
+# Note that in most configurations, by turning this off you will only
+# add latency to these request without any improvement in global hit
+# ratio.
+#
+# If you are inside an firewall see never_direct instead of
+# this directive.
+#Default:
+# nonhierarchical_direct on
+
+# TAG: prefer_direct
+# Normally Squid tries to use parents for most requests. If you for some
+# reason like it to first try going direct and only use a parent if
+# going direct fails set this to on.
+#
+# By combining nonhierarchical_direct off and prefer_direct on you
+# can set up Squid to use a parent as a backup path if going direct
+# fails.
+#
+# Note: If you want Squid to use parents for all requests see
+# the never_direct directive. prefer_direct only modifies how Squid
+# acts on cacheable requests.
+#Default:
+# prefer_direct off
+
+# TAG: always_direct
+# Usage: always_direct allow|deny [!]aclname ...
+#
+# Here you can use ACL elements to specify requests which should
+# ALWAYS be forwarded by Squid to the origin servers without using
+# any peers. For example, to always directly forward requests for
+# local servers ignoring any parents or siblings you may have use
+# something like:
+#
+# acl local-servers dstdomain my.domain.net
+# always_direct allow local-servers
+#
+# To always forward FTP requests directly, use
+#
+# acl FTP proto FTP
+# always_direct allow FTP
+#
+# NOTE: There is a similar, but opposite option named
+# 'never_direct'. You need to be aware that "always_direct deny
+# foo" is NOT the same thing as "never_direct allow foo". You
+# may need to use a deny rule to exclude a more-specific case of
+# some other rule. Example:
+#
+# acl local-external dstdomain external.foo.net
+# acl local-servers dstdomain .foo.net
+# always_direct deny local-external
+# always_direct allow local-servers
+#
+# NOTE: If your goal is to make the client forward the request
+# directly to the origin server bypassing Squid then this needs
+# to be done in the client configuration. Squid configuration
+# can only tell Squid how Squid should fetch the object.
+#
+# NOTE: This directive is not related to caching. The replies
+# is cached as usual even if you use always_direct. To not cache
+# the replies see the 'cache' directive.
+#
+# This clause supports both fast and slow acl types.
+# See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
+#Default:
+# none
+
+# TAG: never_direct
+# Usage: never_direct allow|deny [!]aclname ...
+#
+# never_direct is the opposite of always_direct. Please read
+# the description for always_direct if you have not already.
+#
+# With 'never_direct' you can use ACL elements to specify
+# requests which should NEVER be forwarded directly to origin
+# servers. For example, to force the use of a proxy for all
+# requests, except those in your local domain use something like:
+#
+# acl local-servers dstdomain .foo.net
+# never_direct deny local-servers
+# never_direct allow all
+#
+# or if Squid is inside a firewall and there are local intranet
+# servers inside the firewall use something like:
+#
+# acl local-intranet dstdomain .foo.net
+# acl local-external dstdomain external.foo.net
+# always_direct deny local-external
+# always_direct allow local-intranet
+# never_direct allow all

+# TAG: adaptation_masterx_shared_names
+# For each master transaction (i.e., the HTTP request and response
+# sequence, including all related ICAP and eCAP exchanges), Squid
+# maintains a table of metadata. The table entries are (name, value)
+# pairs shared among eCAP and ICAP exchanges. The table is destroyed
+# with the master transaction.
+#
+# This option specifies the table entry names that Squid must accept
+# from and forward to the adaptation transactions.
+#
+# An ICAP REQMOD or RESPMOD transaction may set an entry in the
+# shared table by returning an ICAP header field with a name
+# specified in adaptation_masterx_shared_names. Squid will store
+# and forward that ICAP header field to subsequent ICAP
+# transactions within the same master transaction scope.
+#
+# Only one shared entry name is supported at this time.

+#Default:
+# dns_timeout 2 minutes
+
+# TAG: dns_defnames on|off
+# Normally the RES_DEFNAMES resolver option is disabled
+# (see res_init(3)). This prevents caches in a hierarchy

+
+# TAG: dns_nameservers
+# Use this if you want to specify a list of DNS name servers
+# (IP addresses) to use instead of those given in your
+# /etc/resolv.conf file.
+# On Windows platforms, if no value is specified here or in

+
+# TAG: ignore_unknown_nameservers
+# By default Squid checks that DNS responses are received
+# from the same IP addresses they are sent to. If they
+# don't match, Squid ignores the response and writes a warning

+#Default:
+# ignore_unknown_nameservers on
+
+# TAG: dns_v4_fallback
+# Standard practice with DNS is to lookup either A or AAAA records
+# and use the results if it succeeds. Only looking up the other if
+# the first attempt fails or otherwise produces no results.
+#
+# That policy however will cause squid to produce error pages for some
+# servers that advertise AAAA but are unreachable over IPv6.
+#
+# If this is ON squid will always lookup both AAAA and A, using both.
+# If this is OFF squid will lookup AAAA and only try A if none found.
+#
+# WARNING: There are some possibly unwanted side-effects with this on:
+# *) Doubles the load placed by squid on the DNS network.

+
+# TAG: dns_v4_first
+# With the IPv6 Internet being as fast or faster than IPv4 Internet
+# for most networks Squid prefers to contact websites over IPv6.
+#
+# This option reverses the order of preference to make Squid contact

+
+# TAG: memory_pools on|off
+# If set, Squid will keep pools of allocated (but unused) memory

+# routines, disable this.
+#Default:
+# memory_pools on
+
+# TAG: memory_pools_limit (bytes)
+# Used only with memory_pools on:
+# memory_pools_limit 50 MB
+#
+# If set to a non-zero value, Squid will keep at most the specified
+# limit of allocated (but unused) memory in memory pools. All free()
+# requests that exceed this limit will be handled by your malloc
+# library. Squid does not pre-allocate any memory, just safe-keeps
+# objects that otherwise would be free()d. Thus, it is safe to set
+# memory_pools_limit to a reasonably high value even if your
+# configuration will use less memory.
+#
+# If set to none, Squid will keep all memory it can. That is, there
+# will be no limit on the total amount of memory used for safe-keeping.
+#
+# To disable memory allocation optimization, do not set
+# memory_pools_limit to 0 or none. Set memory_pools to "off" instead.
+#
+# An overhead for maintaining memory pools is not taken into account
+# when the limit is checked. This overhead is close to four bytes per
+# object kept. However, pools may actually _save_ memory because of
+# reduced memory thrashing in your malloc library.
+#Default:
+# memory_pools_limit 5 MB
+
+# TAG: forwarded_for on|off|transparent|truncate|delete

+#Default:
+# client_db on
+
+# TAG: refresh_all_ims on|off
+# When you enable this option, squid will always check
+# the origin server for an update when a client sends an
+# If-Modified-Since request. Many browsers use IMS
+# requests when the user requests a reload, and this
+# ensures those clients receive the latest version.
+#
+# By default (off), squid may return a Not Modified response
+# based on the age of the cached version.
+#Default:
+# refresh_all_ims off
+
+# TAG: reload_into_ims on|off
+# When you enable this option, client no-cache or ``reload''
+# requests will be changed to If-Modified-Since requests.
+# Doing this VIOLATES the HTTP standard. Enabling this
+# feature could make you liable for problems which it
+# causes.
+#
+# see also refresh_pattern for a more selective approach.
+#Default:
+# reload_into_ims off
+
+# TAG: maximum_single_addr_tries
+# This sets the maximum number of connection attempts for a
+# host that only has one address (for multiple-address hosts,
+# each address is tried once).
+#
+# The default value is one attempt, the (not recommended)
+# maximum is 255 tries. A warning message will be generated
+# if it is set to a value greater than ten.
+#
+# Note: This is in addition to the request re-forwarding which
+# takes place if Squid fails to get a satisfying response.
+#Default:
+# maximum_single_addr_tries 1
+
+# TAG: retry_on_error
+# If set to ON Squid will automatically retry requests when
+# receiving an error response with status 403 (Forbidden),
+# 500 (Internal Error), 501 or 503 (Service not available).
+# Status 502 and 504 (Gateway errors) are always retried.
+#
+# This is mainly useful if you are in a complex cache hierarchy to
+# work around access control errors.
+#
+# NOTE: This retry will attempt to find another working destination.
+# Which is different from the server which just failed.
+#Default:
+# retry_on_error off
+
+# TAG: as_whois_server
+# WHOIS server to query for AS numbers. NOTE: AS numbers are
+# queried only when Squid starts up, not for every request.
+#Default:
+# as_whois_server whois.ra.net
+
+# TAG: offline_mode
+# Enable this option and Squid will never try to validate cached
+# objects.
+#Default:
+# offline_mode off
+
+# TAG: uri_whitespace
+# What to do with requests that have whitespace characters in the
+# URI. Options:
+#
+# strip: The whitespace characters are stripped out of the URL.
+# This is the behavior recommended by RFC2396.
+# deny: The request is denied. The user receives an "Invalid
+# Request" message.
+# allow: The request is allowed and the URI is not changed. The
+# whitespace characters remain in the URI. Note the
+# whitespace is passed to redirector processes if they
+# are in use.
+# encode: The request is allowed and the whitespace characters are
+# encoded according to RFC1738. This could be considered
+# a violation of the HTTP/1.1
+# RFC because proxies are not allowed to rewrite URI's.
+# chop: The request is allowed and the URI is chopped at the
+# first whitespace. This might also be considered a
+# violation.
+#Default:
+# uri_whitespace strip
+
+# TAG: chroot
+# Specifies a directory where Squid should do a chroot() while
+# initializing. This also causes Squid to fully drop root
+# privileges after initializing. This means, for example, if you
+# use a HTTP port less than 1024 and try to reconfigure, you may
+# get an error saying that Squid can not open the port.
+#Default:
+# none
+
+# TAG: balance_on_multiple_ip
+# Modern IP resolvers in squid sort lookup results by preferred access.
+# By default squid will use these IP in order and only rotates to
+# the next listed when the most preffered fails.
+#
+# Some load balancing servers based on round robin DNS have been
+# found not to preserve user session state across requests
+# to different IP addresses.
+#
+# Enabling this directive Squid rotates IP's per request.
+#Default:
+# balance_on_multiple_ip off
+
+# TAG: pipeline_prefetch
+# To boost the performance of pipelined requests to closer
+# match that of a non-proxied environment Squid can try to fetch
+# up to two requests in parallel from a pipeline.
+#
+# Defaults to off for bandwidth management and access logging
+# reasons.
+#
+# WARNING: pipelining breaks NTLM and Negotiate/Kerberos authentication.
+#Default:
+# pipeline_prefetch off
+
+# TAG: high_response_time_warning (msec)
+# If the one-minute median response time exceeds this value,
+# Squid prints a WARNING with debug level 0 to get the
+# administrators attention. The value is in milliseconds.
+#Default:
+# high_response_time_warning 0
+
+# TAG: high_page_fault_warning
+# If the one-minute average page fault rate exceeds this
+# value, Squid prints a WARNING with debug level 0 to get
+# the administrators attention. The value is in page faults
+# per second.
+#Default:
+# high_page_fault_warning 0
+
+# TAG: high_memory_warning
+# If the memory usage (as determined by mallinfo) exceeds
+# this amount, Squid prints a WARNING with debug level 0 to get
+# the administrators attention.
+#Default:
+# high_memory_warning 0 KB
+
+# TAG: sleep_after_fork (microseconds)
+# When this is set to a non-zero value, the main Squid process
+# sleeps the specified number of microseconds after a fork()
+# system call. This sleep may help the situation where your
+# system reports fork() failures due to lack of (virtual)
+# memory. Note, however, if you have a lot of child
+# processes, these sleep delays will add up and your
+# Squid will not service requests for some amount of time
+# until all the child processes have been started.
+# On Windows value less then 1000 (1 milliseconds) are
+# rounded to 1000.
+#Default:
+# sleep_after_fork 0
+
+# TAG: windows_ipaddrchangemonitor on|off
+# On Windows Squid by default will monitor IP address changes and will
+# reconfigure itself after any detected event. This is very useful for
+# proxies connected to internet with dial-up interfaces.
+# In some cases (a Proxy server acting as VPN gateway is one) it could be
+# desiderable to disable this behaviour setting this to 'off'.
+# Note: after changing this, Squid service must be restarted.
+#Default:
+# windows_ipaddrchangemonitor on
+
+# TAG: max_filedescriptors
+# The maximum number of filedescriptors supported.
+#
+# The default "0" means Squid inherits the current ulimit setting.
+#
+# Note: Changing this requires a restart of Squid. Also
+# not all comm loops supports large values.
+#Default:
+# max_filedescriptors 0

+# WELCOME TO SQUID 3.1.20
+# ----------------------------
+#
+# This is the documentation for the Squid configuration file.
+# This documentation can also be found online at:
+# http://www.squid-cache.org/Doc/config/
+#
+# You may wish to look at the Squid home page and wiki for the
+# FAQ and other documentation:
+# http://www.squid-cache.org/
+# http://wiki.squid-cache.org/SquidFaq
+# http://wiki.squid-cache.org/ConfigExamples
+#
+# This documentation shows what the defaults for various directives
+# happen to be. If you don't need to change the default, you should
+# leave the line out of your squid.conf in most cases.
+#
+# In some cases "none" refers to no default setting at all,
+# while in other cases it refers to the value of the option
+# - the comments for that keyword indicate if this is the case.
+#
+
+# Configuration options can be included using the "include" directive.
+# Include takes a list of files to include. Quoting and wildcards are
+# supported.
+#
+# For example,
+#
+# include /path/to/included/file/squid.acl.config
+#
+# Includes can be nested up to a hard-coded depth of 16 levels.
+# This arbitrary restriction is to prevent recursive include references
+# from causing Squid entering an infinite loop whilst trying to load
+# configuration files.
+
+# TAG: dns_testnames
+# Remove this line. DNS is no longer tested on startup.
+#Default:
+# none
+
+# TAG: extension_methods
+# Remove this line. All valid methods for HTTP are accepted by default.
+#Default:

+
+# OPTIONS FOR AUTHENTICATION
+# -----------------------------------------------------------------------------
+
+# TAG: auth_param
+# This is used to define parameters for the various authentication
+# schemes supported by Squid.
+#
+# format: auth_param scheme parameter [setting]
+#
+# The order in which authentication schemes are presented to the client is
+# dependent on the order the scheme first appears in config file. IE
+# has a bug (it's not RFC 2617 compliant) in that it will use the basic
+# scheme if basic is the first entry presented, even if more secure
+# schemes are presented. For now use the order in the recommended
+# settings section below. If other browsers have difficulties (don't
+# recognize the schemes offered even if you are using basic) either
+# put basic first, or disable the other schemes (by commenting out their
+# program entry).
+#
+# Once an authentication scheme is fully configured, it can only be
+# shutdown by shutting squid down and restarting. Changes can be made on
+# the fly and activated with a reconfigure. I.E. You can change to a
+# different helper, but not unconfigure the helper completely.
+#
+# Please note that while this directive defines how Squid processes
+# authentication it does not automatically activate authentication.
+# To use authentication you must in addition make use of ACLs based
+# on login name in http_access (proxy_auth, proxy_auth_regex or
+# external with %LOGIN used in the format tag). The browser will be
+# challenged for authentication on the first such acl encountered
+# in http_access processing and will also be re-challenged for new
+# login credentials if the request is being denied by a proxy_auth
+# type acl.
+#
+# WARNING: authentication can't be used in a transparently intercepting
+# proxy as the client then thinks it is talking to an origin server and
+# not the proxy. This is a limitation of bending the TCP/IP protocol to
+# transparently intercepting port 80, not a limitation in Squid.
+# Ports flagged 'transparent', 'intercept', or 'tproxy' have
+# authentication disabled.
+#
+# === Parameters for the basic scheme follow. ===
+#
+# "program" cmdline
+# Specify the command for the external authenticator. Such a program
+# reads a line containing "username password" and replies "OK" or
+# "ERR" in an endless loop. "ERR" responses may optionally be followed
+# by a error description available as %m in the returned error page.
+# If you use an authenticator, make sure you have 1 acl of type
+# proxy_auth.
+#
+# By default, the basic authentication scheme is not used unless a
+# program is specified.
+#
+# If you want to use the traditional NCSA proxy authentication, set
+# this line to something like
+#
+# auth_param basic program /usr/lib/squid3/ncsa_auth /usr/etc/passwd
+#
+# "utf8" on|off
+# HTTP uses iso-latin-1 as characterset, while some authentication
+# backends such as LDAP expects UTF-8. If this is set to on Squid will
+# translate the HTTP iso-latin-1 charset to UTF-8 before sending the
+# username & password to the helper.
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn. If you start too few
+# Squid will have to wait for them to process a backlog of credential
+# verifications, slowing it down. When password verifications are
+# done via a (slow) network you are likely to need lots of
+# authenticator processes.
+# auth_param basic children 5
+#
+# "concurrency" concurrency
+# The number of concurrent requests the helper can process.
+# The default of 0 is used for helpers who only supports
+# one request at a time. Setting this changes the protocol used to
+# include a channel number first on the request/response line, allowing
+# multiple requests to be sent to the same helper in parallell without
+# wating for the response.
+# Must not be set unless it's known the helper supports this.
+# auth_param basic concurrency 0
+#
+# "realm" realmstring
+# Specifies the realm name which is to be reported to the
+# client for the basic proxy authentication scheme (part of
+# the text the user will see when prompted their username and
+# password). There is no default.
+# auth_param basic realm Squid proxy-caching web server
+#
+# "credentialsttl" timetolive
+# Specifies how long squid assumes an externally validated
+# username:password pair is valid for - in other words how
+# often the helper program is called for that user. Set this
+# low to force revalidation with short lived passwords. Note
+# setting this high does not impact your susceptibility
+# to replay attacks unless you are using an one-time password
+# system (such as SecureID). If you are using such a system,
+# you will be vulnerable to replay attacks unless you also
+# use the max_user_ip ACL in an http_access rule.
+#
+# "casesensitive" on|off
+# Specifies if usernames are case sensitive. Most user databases are
+# case insensitive allowing the same username to be spelled using both
+# lower and upper case letters, but some are case sensitive. This
+# makes a big difference for user_max_ip ACL processing and similar.
+# auth_param basic casesensitive off
+#
+# === Parameters for the digest scheme follow ===
+#
+# "program" cmdline
+# Specify the command for the external authenticator. Such
+# a program reads a line containing "username":"realm" and
+# replies with the appropriate H(A1) value hex encoded or
+# ERR if the user (or his H(A1) hash) does not exists.
+# See rfc 2616 for the definition of H(A1).
+# "ERR" responses may optionally be followed by a error description
+# available as %m in the returned error page.
+#
+# By default, the digest authentication scheme is not used unless a
+# program is specified.
+#
+# If you want to use a digest authenticator, set this line to
+# something like
+#
+# auth_param digest program /usr/lib/squid3/digest_pw_auth /usr/etc/digpass
+#
+# "utf8" on|off
+# HTTP uses iso-latin-1 as characterset, while some authentication
+# backends such as LDAP expects UTF-8. If this is set to on Squid will
+# translate the HTTP iso-latin-1 charset to UTF-8 before sending the
+# username & password to the helper.
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to
+# process a backlog of H(A1) calculations, slowing it down.
+# When the H(A1) calculations are done via a (slow) network
+# you are likely to need lots of authenticator processes.
+# auth_param digest children 5
+#
+# "realm" realmstring
+# Specifies the realm name which is to be reported to the
+# client for the digest proxy authentication scheme (part of
+# the text the user will see when prompted their username and
+# password). There is no default.
+# auth_param digest realm Squid proxy-caching web server
+#
+# "nonce_garbage_interval" timeinterval
+# Specifies the interval that nonces that have been issued
+# to client_agent's are checked for validity.
+#
+# "nonce_max_duration" timeinterval
+# Specifies the maximum length of time a given nonce will be
+# valid for.
+#
+# "nonce_max_count" number
+# Specifies the maximum number of times a given nonce can be
+# used.
+#
+# "nonce_strictness" on|off
+# Determines if squid requires strict increment-by-1 behavior
+# for nonce counts, or just incrementing (off - for use when
+# useragents generate nonce counts that occasionally miss 1
+# (ie, 1,2,4,6)). Default off.
+#
+# "check_nonce_count" on|off
+# This directive if set to off can disable the nonce count check
+# completely to work around buggy digest qop implementations in
+# certain mainstream browser versions. Default on to check the
+# nonce count to protect from authentication replay attacks.
+#
+# "post_workaround" on|off
+# This is a workaround to certain buggy browsers who sends
+# an incorrect request digest in POST requests when reusing
+# the same nonce as acquired earlier on a GET request.
+#
+# === NTLM scheme options follow ===
+#
+# "program" cmdline
+# Specify the command for the external NTLM authenticator.
+# Such a program reads exchanged NTLMSSP packets with
+# the browser via Squid until authentication is completed.
+# If you use an NTLM authenticator, make sure you have 1 acl
+# of type proxy_auth. By default, the NTLM authenticator_program
+# is not used.
+#
+# auth_param ntlm program /usr/lib/squid3/ntlm_auth
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to
+# process a backlog of credential verifications, slowing it
+# down. When credential verifications are done via a (slow)
+# network you are likely to need lots of authenticator
+# processes.
+#
+# auth_param ntlm children 5
+#
+# "keep_alive" on|off
+# Whether to keep the connection open after the initial response where
+# Squid tells the browser which schemes are supported by the proxy.
+# Some browsers are known to present many login popups or to corrupt
+# POST/PUT requests transfer if the connection is not closed.
+# The default is currently OFF to avoid this, but may change.
+#
+# auth_param ntlm keep_alive on
+#
+# === Options for configuring the NEGOTIATE auth-scheme follow ===
+#
+# "program" cmdline
+# Specify the command for the external Negotiate authenticator.
+# This protocol is used in Microsoft Active-Directory enabled setups with
+# the Microsoft Internet Explorer or Mozilla Firefox browsers.
+# Its main purpose is to exchange credentials with the Squid proxy
+# using the Kerberos mechanisms.
+# If you use a Negotiate authenticator, make sure you have at least
+# one acl of type proxy_auth active. By default, the negotiate
+# authenticator_program is not used.
+# The only supported program for this role is the ntlm_auth
+# program distributed as part of Samba, version 4 or later.
+#
+# auth_param negotiate program /usr/lib/squid3/ntlm_auth --helper-protocol=gss-spnego
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to
+# process a backlog of credential verifications, slowing it
+# down. When crendential verifications are done via a (slow)
+# network you are likely to need lots of authenticator
+# processes.
+# auth_param negotiate children 5
+#
+# "keep_alive" on|off
+# Whether to keep the connection open after the initial response where
+# Squid tells the browser which schemes are supported by the proxy.
+# Some browsers are known to present many login popups or to corrupt
+# POST/PUT requests transfer if the connection is not closed.
+# The default is currently OFF to avoid this, but may change.
+#
+# auth_param negotiate keep_alive on
+#
+#
+# Examples:
+#
+##Recommended minimum configuration per scheme:
+##auth_param negotiate program <uncomment and complete this line to activate>
+##auth_param negotiate children 5
+##auth_param negotiate keep_alive on
+##
+##auth_param ntlm program <uncomment and complete this line to activate>
+##auth_param ntlm children 5
+##auth_param ntlm keep_alive on
+##
+##auth_param digest program <uncomment and complete this line>
+##auth_param digest children 5
+##auth_param digest realm Squid proxy-caching web server
+##auth_param digest nonce_garbage_interval 5 minutes
+##auth_param digest nonce_max_duration 30 minutes
+##auth_param digest nonce_max_count 50
+##
+##auth_param basic program <uncomment and complete this line>
+##auth_param basic children 5
+##auth_param basic realm Squid proxy-caching web server
+##auth_param basic credentialsttl 2 hours
+#Default:
+# none
+
+# TAG: authenticate_cache_garbage_interval
+# The time period between garbage collection across the username cache.
+# This is a tradeoff between memory utilization (long intervals - say
+# 2 days) and CPU (short intervals - say 1 minute). Only change if you
+# have good reason to.
+#Default:
+# authenticate_cache_garbage_interval 1 hour
+
+# TAG: authenticate_ttl
+# The time a user & their credentials stay in the logged in
+# user cache since their last request. When the garbage
+# interval passes, all user credentials that have passed their
+# TTL are removed from memory.
+#Default:
+# authenticate_ttl 1 hour
+
+# TAG: authenticate_ip_ttl
+# If you use proxy authentication and the 'max_user_ip' ACL,
+# this directive controls how long Squid remembers the IP
+# addresses associated with each user. Use a small value
+# (e.g., 60 seconds) if your users might change addresses
+# quickly, as is the case with dialups. You might be safe
+# using a larger value (e.g., 2 hours) in a corporate LAN
+# environment with relatively static address assignments.
+#Default:
+# authenticate_ip_ttl 0 seconds
+
+# ACCESS CONTROLS
+# -----------------------------------------------------------------------------
+
+# TAG: external_acl_type
+# This option defines external acl classes using a helper program
+# to look up the status
+#
+# external_acl_type name [options] FORMAT.. /path/to/helper [helper arguments..]
+#
+# Options:
+#
+# ttl=n TTL in seconds for cached results (defaults to 3600
+# for 1 hour)
+# negative_ttl=n
+# TTL for cached negative lookups (default same
+# as ttl)
+# children=n Number of acl helper processes spawn to service

+#
+# %% The percent sign. Useful for helpers which need
+# an unchanging input format.
+#
+# In addition to the above, any string specified in the referencing
+# acl will also be included in the helper request line, after the
+# specified formats (see the "acl external" directive)
+#
+# The helper receives lines per the above format specification,
+# and returns lines starting with OK or ERR indicating the validity
+# of the request and optionally followed by additional keywords with
+# more details.
+#
+# General result syntax:
+#
+# OK/ERR keyword=value ...
+#
+# Defined keywords:
+#
+# user= The users name (login)
+# password= The users password (for login= cache_peer option)
+# message= Message describing the reason. Available as %o
+# in error pages
+# tag= Apply a tag to a request (for both ERR and OK results)
+# Only sets a tag, does not alter existing tags.
+# log= String to be logged in access.log. Available as
+# %ea in logformat specifications
+#
+# If protocol=3.0 (the default) then URL escaping is used to protect
+# each value in both requests and responses.
+#
+# If using protocol=2.5 then all values need to be enclosed in quotes
+# if they may contain whitespace, or the whitespace escaped using \.
+# And quotes or \ characters within the keyword value must be \ escaped.
+#
+# When using the concurrency= option the protocol is changed by
+# introducing a query channel tag infront of the request/response.
+# The query channel tag is a number between 0 and concurrency-1.
+#Default:
+# none
+
+# TAG: acl
+# Defining an Access List
+#
+# Every access list definition must begin with an aclname and acltype,
+# followed by either type-specific arguments or a quoted filename that
+# they are read from.
+#
+# acl aclname acltype argument ...
+# acl aclname acltype "file" ...
+#
+# When using "file", the file should contain one item per line.
+#
+# By default, regular expressions are CASE-SENSITIVE.
+# To make them case-insensitive, use the -i option. To return case-sensitive
+# use the +i option between patterns, or make a new ACL line without -i.
+#
+# Some acl types require suspending the current request in order
+# to access some external data source.
+# Those which do are marked with the tag [slow], those which
+# don't are marked as [fast].
+# See http://wiki.squid-cache.org/SquidFaq/SquidAcl

+#
+# Requests may pass through a chain of several other proxies

+# comma-separated list of the IP addresses in the chain, with the
+# rightmost address being the most recent.
+#
+# If a request reaches us from a source that is allowed by this
+# configuration item, then we consult the X-Forwarded-For header
+# to see where that host received the request from. If the
+# X-Forwarded-For header contains multiple addresses, we continue
+# backtracking until we reach an address for which we are not allowed
+# to follow the X-Forwarded-For header, or until we reach the first
+# address in the list. For the purpose of ACL used in the
+# follow_x_forwarded_for directive the src ACL type always matches
+# the address we are testing and srcdomain matches its rDNS.
+#
+# The end result of this process is an IP address that we will
+# refer to as the indirect client address. This address may
+# be treated as the client address for access control, ICAP, delay

+# IPv6 Magic:

+# side of the IPv4/IPv6 boundary.
+#
+# To operate with tcp_outgoing_address and keep the bridging benefits
+# an additional ACL needs to be used which ensures the IPv6-bound traffic
+# is never forced or permitted out the IPv4 interface.
+#
+# # IPv6 destination test along with a dummy access control to perform the required DNS
+# # This MUST be place before any ALLOW rules.

+# OPTIONS WHICH AFFECT THE NEIGHBOR SELECTION ALGORITHM
+# -----------------------------------------------------------------------------
+
+# TAG: cache_peer
+# To specify other caches in a hierarchy, use the format:
+#
+# cache_peer hostname type http-port icp-port [options]
+#
+# For example,
+#
+# # proxy icp
+# # hostname type port port options
+# # -------------------- -------- ----- ----- -----------
+# cache_peer parent.foo.net parent 3128 3130 default
+# cache_peer sib1.foo.net sibling 3128 3130 proxy-only
+# cache_peer sib2.foo.net sibling 3128 3130 proxy-only
+# cache_peer example.com parent 80 0 default
+# cache_peer cdn.example.com sibling 3128 0
+#
+# type: either 'parent', 'sibling', or 'multicast'.
+#
+# proxy-port: The port number where the peer accept HTTP requests.
+# For other Squid proxies this is usually 3128
+# For web servers this is usually 80
+#
+# icp-port: Used for querying neighbor caches about objects.
+# Set to 0 if the peer does not support ICP or HTCP.
+# See ICP and HTCP options below for additional details.
+#
+#
+# ==== ICP OPTIONS ====
+#
+# You MUST also set icp_port and icp_access explicitly when using these options.
+# The defaults will prevent peer traffic using ICP.
+#
+#
+# no-query Disable ICP queries to this neighbor.
+#
+# multicast-responder
+# Indicates the named peer is a member of a multicast group.
+# ICP queries will not be sent directly to the peer, but ICP
+# replies will be accepted from it.
+#
+# closest-only Indicates that, for ICP_OP_MISS replies, we'll only forward
+# CLOSEST_PARENT_MISSes and never FIRST_PARENT_MISSes.
+#
+# background-ping
+# To only send ICP queries to this neighbor infrequently.
+# This is used to keep the neighbor round trip time updated
+# and is usually used in conjunction with weighted-round-robin.
+#
+#
+# ==== HTCP OPTIONS ====
+#
+# You MUST also set htcp_port and htcp_access explicitly when using these options.
+# The defaults will prevent peer traffic using HTCP.
+#
+#
+# htcp Send HTCP, instead of ICP, queries to the neighbor.
+# You probably also want to set the "icp-port" to 4827
+# instead of 3130.
+#
+# htcp-oldsquid Send HTCP to old Squid versions.
+#
+# htcp-no-clr Send HTCP to the neighbor but without
+# sending any CLR requests. This cannot be used with
+# htcp-only-clr.
+#
+# htcp-only-clr Send HTCP to the neighbor but ONLY CLR requests.
+# This cannot be used with htcp-no-clr.
+#
+# htcp-no-purge-clr
+# Send HTCP to the neighbor including CLRs but only when
+# they do not result from PURGE requests.
+#
+# htcp-forward-clr
+# Forward any HTCP CLR requests this proxy receives to the peer.
+#
+#
+# ==== PEER SELECTION METHODS ====
+#
+# The default peer selection method is ICP, with the first responding peer
+# being used as source. These options can be used for better load balancing.
+#
+#
+# default This is a parent cache which can be used as a "last-resort"
+# if a peer cannot be located by any of the peer-selection methods.
+# If specified more than once, only the first is used.
+#
+# round-robin Load-Balance parents which should be used in a round-robin
+# fashion in the absence of any ICP queries.
+# weight=N can be used to add bias.
+#
+# weighted-round-robin
+# Load-Balance parents which should be used in a round-robin
+# fashion with the frequency of each parent being based on the
+# round trip time. Closer parents are used more often.
+# Usually used for background-ping parents.
+# weight=N can be used to add bias.
+#
+# carp Load-Balance parents which should be used as a CARP array.
+# The requests will be distributed among the parents based on the
+# CARP load balancing hash function based on their weight.
+#
+# userhash Load-balance parents based on the client proxy_auth or ident username.
+#
+# sourcehash Load-balance parents based on the client source IP.
+#
+# multicast-siblings
+# To be used only for cache peers of type "multicast".
+# ALL members of this multicast group have "sibling"
+# relationship with it, not "parent". This is to a multicast
+# group when the requested object would be fetched only from
+# a "parent" cache, anyway. It's useful, e.g., when
+# configuring a pool of redundant Squid proxies, being
+# members of the same multicast group.
+#
+#
+# ==== PEER SELECTION OPTIONS ====
+#
+# weight=N use to affect the selection of a peer during any weighted
+# peer-selection mechanisms.
+# The weight must be an integer; default is 1,
+# larger weights are favored more.
+# This option does not affect parent selection if a peering
+# protocol is not in use.
+#
+# basetime=N Specify a base amount to be subtracted from round trip
+# times of parents.
+# It is subtracted before division by weight in calculating
+# which parent to fectch from. If the rtt is less than the
+# base time the rtt is set to a minimal value.
+#
+# ttl=N Specify a TTL to use when sending multicast ICP queries
+# to this address.
+# Only useful when sending to a multicast group.
+# Because we don't accept ICP replies from random
+# hosts, you must configure other group members as
+# peers with the 'multicast-responder' option.
+#
+# no-delay To prevent access to this neighbor from influencing the
+# delay pools.
+#
+# digest-url=URL Tell Squid to fetch the cache digest (if digests are
+# enabled) for this host from the specified URL rather
+# than the Squid default location.
+#
+#
+# ==== ACCELERATOR / REVERSE-PROXY OPTIONS ====
+#
+# originserver Causes this parent to be contacted as an origin server.
+# Meant to be used in accelerator setups when the peer
+# is a web server.
+#
+# forceddomain=name
+# Set the Host header of requests forwarded to this peer.
+# Useful in accelerator setups where the server (peer)
+# expects a certain domain name but clients may request
+# others. ie example.com or www.example.com
+#
+# no-digest Disable request of cache digests.
+#
+# no-netdb-exchange
+# Disables requesting ICMP RTT database (NetDB).
+#
+#
+# ==== AUTHENTICATION OPTIONS ====
+#
+# login=user:password
+# If this is a personal/workgroup proxy and your parent
+# requires proxy authentication.
+#
+# Note: The string can include URL escapes (i.e. %20 for
+# spaces). This also means % must be written as %%.
+#
+# login=PROXYPASS
+# Send login details received from client to this peer.
+# Authentication is not required, nor changed.
+#
+# Note: This will pass any form of authentication but
+# only Basic auth will work through a proxy unless the
+# connection-auth options are also used.
+#
+# login=PASS Send login details received from client to this peer.
+# Authentication is not required by this option.
+# If there are no client-provided authentication headers
+# to pass on, but username and password are available
+# from either proxy login or an external ACL user= and
+# password= result tags they may be sent instead.
+#
+# Note: To combine this with proxy_auth both proxies must
+# share the same user database as HTTP only allows for
+# a single login (one for proxy, one for origin server).
+# Also be warned this will expose your users proxy
+# password to the peer. USE WITH CAUTION
+#
+# login=*:password
+# Send the username to the upstream cache, but with a
+# fixed password. This is meant to be used when the peer
+# is in another administrative domain, but it is still
+# needed to identify each user.
+# The star can optionally be followed by some extra
+# information which is added to the username. This can
+# be used to identify this proxy to the peer, similar to
+# the login=username:password option above.
+#
+# connection-auth=on|off
+# Tell Squid that this peer does or not support Microsoft
+# connection oriented authentication, and any such
+# challenges received from there should be ignored.
+# Default is auto to automatically determine the status
+# of the peer.
+#
+#
+# ==== SSL / HTTPS / TLS OPTIONS ====
+#
+# ssl Encrypt connections to this peer with SSL/TLS.
+#
+# sslcert=/path/to/ssl/certificate
+# A client SSL certificate to use when connecting to
+# this peer.
+#
+# sslkey=/path/to/ssl/key
+# The private SSL key corresponding to sslcert above.
+# If 'sslkey' is not specified 'sslcert' is assumed to
+# reference a combined file containing both the
+# certificate and the key.
+#
+# sslversion=1|2|3|4
+# The SSL version to use when connecting to this peer
+# 1 = automatic (default)
+# 2 = SSL v2 only

+# NO_SSLv3 Disallow the use of SSLv3
+# NO_TLSv1 Disallow the use of TLSv1
+# See src/ssl_support.c or the OpenSSL documentation for
+# a more complete list.
+#
+# sslcafile=... A file containing additional CA certificates to use
+# when verifying the peer certificate.
+#
+# sslcapath=... A directory containing additional CA certificates to
+# use when verifying the peer certificate.
+#
+# sslcrlfile=... A certificate revocation list file to use when
+# verifying the peer certificate.
+#
+# sslflags=... Specify various flags modifying the SSL implementation:
+#
+# DONT_VERIFY_PEER
+# Accept certificates even if they fail to
+# verify.
+# NO_DEFAULT_CA
+# Don't use the default CA list built in
+# to OpenSSL.
+# DONT_VERIFY_DOMAIN
+# Don't verify the peer certificate
+# matches the server name
+#
+# ssldomain= The peer name as advertised in it's certificate.
+# Used for verifying the correctness of the received peer
+# certificate. If not specified the peer hostname will be
+# used.
+#
+# front-end-https
+# Enable the "Front-End-Https: On" header needed when
+# using Squid as a SSL frontend in front of Microsoft OWA.
+# See MS KB document Q307347 for details on this header.
+# If set to auto the header will only be added if the
+# request is forwarded as a https:// URL.
+#
+#
+# ==== GENERAL OPTIONS ====
+#
+# connect-timeout=N
+# A peer-specific connect timeout.
+# Also see the peer_connect_timeout directive.
+#
+# connect-fail-limit=N
+# How many times connecting to a peer must fail before
+# it is marked as down. Default is 10.
+#
+# allow-miss Disable Squid's use of only-if-cached when forwarding
+# requests to siblings. This is primarily useful when
+# icp_hit_stale is used by the sibling. To extensive use
+# of this option may result in forwarding loops, and you
+# should avoid having two-way peerings with this option.
+# For example to deny peer usage on requests from peer
+# by denying cache_peer_access if the source is a peer.
+#
+# max-conn=N Limit the amount of connections Squid may open to this
+# peer. see also
+#
+# name=xxx Unique name for the peer.
+# Required if you have multiple peers on the same host

+#
+# proxy-only objects fetched from the peer will not be stored locally.
+#
+#Default:
+# none
+
+# TAG: cache_peer_domain
+# Use to limit the domains for which a neighbor cache will be
+# queried. Usage:
+#
+# cache_peer_domain cache-host domain [domain ...]
+# cache_peer_domain cache-host !domain
+#
+# For example, specifying
+#
+# cache_peer_domain parent.foo.net .edu
+#
+# has the effect such that UDP query packets are sent to
+# 'bigserver' only when the requested object exists on a
+# server in the .edu domain. Prefixing the domainname
+# with '!' means the cache will be queried for objects
+# NOT in that domain.
+#
+# NOTE: * Any number of domains may be given for a cache-host,
+# either on the same or separate lines.
+# * When multiple domains are given for a particular
+# cache-host, the first matched domain is applied.
+# * Cache hosts with no domain restrictions are queried
+# for all requests.

+#
+# Modifying the neighbor type for specific domains is now

+# Normally it should only be necessary to list domains which

+# applies for hostnames which do not match domains listed here.
+#
+#EXAMPLE:

+# TAG: dead_peer_timeout (seconds)
+# This controls how long Squid waits to declare a peer cache
+# as "dead." If there are no ICP replies received in this

+# expect to receive any further ICP replies. However, it
+# continues to send ICP queries, and will mark the peer as
+# alive upon receipt of the first subsequent ICP reply.
+#
+# This timeout also affects when Squid expects to receive ICP
+# replies from peers. If more than 'dead_peer' seconds have
+# passed since the last ICP reply was received, Squid will not
+# expect to receive an ICP reply on the next query. Thus, if
+# your time between requests is greater than this timeout, you

+# MEMORY CACHE OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: cache_mem (bytes)
+# NOTE: THIS PARAMETER DOES NOT SPECIFY THE MAXIMUM PROCESS SIZE.

+# USE AS A MEMORY CACHE OF OBJECTS. SQUID USES MEMORY FOR OTHER
+# THINGS AS WELL. SEE THE SQUID FAQ SECTION 8 FOR DETAILS.
+#
+# 'cache_mem' specifies the ideal amount of memory to be used
+# for:
+# * In-Transit objects
+# * Hot Objects
+# * Negative-Cached objects
+#
+# Data for these objects are stored in 4 KB blocks. This
+# parameter specifies the ideal upper limit on the total size of
+# 4 KB blocks allocated. In-Transit objects take the highest
+# priority.
+#
+# In-transit objects have priority over the others. When
+# additional space is needed for incoming data, negative-cached
+# and hot objects will be released. In other words, the
+# negative-cached and hot objects will fill up any unused space
+# not needed for in-transit objects.
+#
+# If circumstances require, this limit will be exceeded.
+# Specifically, if your incoming request rate requires more than
+# 'cache_mem' of memory to hold in-transit objects, Squid will
+# exceed this limit to satisfy the new requests. When the load
+# decreases, blocks will be freed until the high-water mark is
+# reached. Thereafter, blocks will be used to store hot
+# objects.
+#Default:
+# cache_mem 256 MB
+
+# TAG: maximum_object_size_in_memory (bytes)

+# lru : Squid's original list based LRU policy
+# heap GDSF : Greedy-Dual Size Frequency
+# heap LFUDA: Least Frequently Used with Dynamic Aging
+# heap LRU : LRU policy implemented using a heap
+#
+# Applies to any cache_dir lines listed below this.
+#
+# The LRU policies keeps recently referenced objects.
+#
+# The heap GDSF policy optimizes object hit rate by keeping smaller
+# popular objects in cache so it has a better chance of getting a
+# hit. It achieves a lower byte hit rate than LFUDA though since
+# it evicts larger (possibly popular) objects.
+#
+# The heap LFUDA policy keeps popular objects in cache regardless of
+# their size and thus optimizes byte hit rate at the expense of
+# hit rate since one large, popular object will prevent many
+# smaller, slightly less popular objects from being cached.
+#
+# Both policies utilize a dynamic aging mechanism that prevents
+# cache pollution that can otherwise occur with frequency-based
+# replacement policies.
+#
+# NOTE: if using the LFUDA replacement policy you should increase

+#
+# 'Directory' is a top-level directory where cache swap
+# files will be stored. If you want to use an entire disk
+# for caching, this can be the mount-point directory.
+# The directory must exist and be writable by the Squid
+# process. Squid will NOT create this directory for you.

+# The ufs store type:
+#
+# "ufs" is the old well-known Squid storage format that has always
+# been there.
+#
+# cache_dir ufs Directory-Name Mbytes L1 L2 [options]
+#
+# 'Mbytes' is the amount of disk space (MB) to use under this
+# directory. The default is 100 MB. Change this to suit your
+# configuration. Do NOT put the size of your disk drive here.
+# Instead, if you want Squid to use the entire disk drive,

+#
+# 'L2' is the number of second-level subdirectories which
+# will be created under each first-level directory. The default
+# is 256.
+#
+# The aufs store type:
+#
+# "aufs" uses the same storage format as "ufs", utilizing

+# disk-I/O. This was formerly known in Squid as async-io.
+#

+# disk-I/O.
+#
+# cache_dir diskd Directory-Name Mbytes L1 L2 [options] [Q1=n] [Q2=n]
+#
+# see argument descriptions under ufs above
+#
+# Q1 specifies the number of unacknowledged I/O requests when Squid

+# block-size=n defines the "block size" for COSS cache_dir's.
+# Squid uses file numbers as block numbers. Since file numbers
+# are limited to 24 bits, the block size determines the maximum
+# size of the COSS partition. The default is 512 bytes, which
+# leads to a maximum cache_dir size of 512<<24, or 8 GB. Note
+# you should not change the coss block size after Squid
+# has written some objects to the cache_dir.
+#
+# The coss file store has changed from 2.5. Now it uses a file
+# called 'stripe' in the directory names in the config - and
+# this will be created by squid -z.
+#
+# Common options:
+#
+# no-store, no new objects should be stored to this cache_dir
+#
+# max-size=n, refers to the max object size in bytes this cache_dir
+# supports. It is used to select the cache_dir to store the object.
+# Note: To make optimal use of the max-size limits you should order
+# the cache_dir lines with the smallest max-size value first and the
+# ones with no max-size specification last.
+#
+# Note for coss, max-size must be less than COSS_MEMBUF_SZ,

+# TAG: ie_refresh on|off
+# Microsoft Internet Explorer up until version 5.5 Service
+# Pack 1 has an issue with transparent proxies, wherein it
+# is impossible to force a refresh. Turning this on provides
+# a partial fix to the problem, by causing all IMS-REFRESH
+# requests from older IE versions to check the origin server
+# for fresh content. This reduces hit ratio by some amount
+# (~10% in my experience), but allows users to actually get
+# fresh content when they want it. Note because Squid
+# cannot tell if the user is using 5.5 or 5.5SP1, the behavior
+# of 5.5 is unchanged from old versions of Squid (i.e. a
+# forced refresh is impossible). Newer versions of IE will,
+# hopefully, continue to have the new behavior and will be
+# handled based on that assumption. This option defaults to
+# the old Squid behavior, which is better for hit ratios but
+# worse for clients using IE, if they need to be able to

+#Default:
+# delay_pools 0
+
+# TAG: delay_class
+# This defines the class of each delay pool. There must be exactly one
+# delay_class line for each delay pool. For example, to define two
+# delay pools, one of class 2 and one of class 3, the settings above
+# and here would be:
+#
+# Example:
+# delay_pools 4 # 4 delay pools
+# delay_class 1 2 # pool 1 is a class 2 pool
+# delay_class 2 3 # pool 2 is a class 3 pool
+# delay_class 3 4 # pool 3 is a class 4 pool
+# delay_class 4 5 # pool 4 is a class 5 pool
+#
+# The delay pool classes are:
+#
+# class 1 Everything is limited by a single aggregate
+# bucket.
+#
+# class 2 Everything is limited by a single aggregate
+# bucket as well as an "individual" bucket chosen
+# from bits 25 through 32 of the IPv4 address.
+#
+# class 3 Everything is limited by a single aggregate
+# bucket as well as a "network" bucket chosen
+# from bits 17 through 24 of the IP address and a
+# "individual" bucket chosen from bits 17 through
+# 32 of the IPv4 address.
+#
+# class 4 Everything in a class 3 delay pool, with an
+# additional limit on a per user basis. This
+# only takes effect if the username is established
+# in advance - by forcing authentication in your
+# http_access rules.
+#
+# class 5 Requests are grouped according their tag (see
+# external_acl's tag= reply).
+#
+#
+# Each pool also requires a delay_parameters directive to configure the pool size
+# and speed limits used whenever the pool is applied to a request. Along with
+# a set of delay_access directives to determine when it is used.
+#
+# NOTE: If an IP address is a.b.c.d
+# -> bits 25 through 32 are "d"
+# -> bits 17 through 24 are "c"
+# -> bits 17 through 32 are "c * 256 + d"
+#
+# NOTE-2: Due to the use of bitmasks in class 2,3,4 pools they only apply to
+# IPv4 traffic. Class 1 and 5 pools may be used with IPv6 traffic.
+#Default:
+# none
+
+# TAG: delay_access
+# This is used to determine which delay pool a request falls into.
+#
+# delay_access is sorted per pool and the matching starts with pool 1,
+# then pool 2, ..., and finally pool N. The first delay pool where the
+# request is allowed is selected for the request. If it does not allow

+#
+# For example, if you want some_big_clients in delay

+
+# TAG: delay_parameters
+# This defines the parameters for a delay pool. Each delay pool has
+# a number of "buckets" associated with it, as explained in the
+# description of delay_class.
+#
+# For a class 1 delay pool, the syntax is:
+# delay_pools pool 1
+# delay_parameters pool aggregate
+#
+# For a class 2 delay pool:
+# delay_pools pool 2
+# delay_parameters pool aggregate individual
+#
+# For a class 3 delay pool:
+# delay_pools pool 3
+# delay_parameters pool aggregate network individual
+#
+# For a class 4 delay pool:
+# delay_pools pool 4
+# delay_parameters pool aggregate network individual user
+#
+# For a class 5 delay pool:
+# delay_pools pool 5
+# delay_parameters pool tagrate
+#
+# The option variables are:
+#
+# pool a pool number - ie, a number between 1 and the
+# number specified in delay_pools as used in
+# delay_class lines.
+#
+# aggregate the speed limit parameters for the aggregate bucket
+# (class 1, 2, 3).
+#
+# individual the speed limit parameters for the individual
+# buckets (class 2, 3).
+#
+# network the speed limit parameters for the network buckets
+# (class 3).
+#
+# user the speed limit parameters for the user buckets
+# (class 4).
+#
+# tagrate the speed limit parameters for the tag buckets
+# (class 5).
+#
+# A pair of delay parameters is written restore/maximum, where restore is
+# the number of bytes (not bits - modem and network speeds are usually
+# quoted in bits) per second placed into the bucket, and maximum is the
+# maximum number of bytes which can be in the bucket at any time.
+#
+# There must be one delay_parameters line for each delay pool.
+#
+#
+# For example, if delay pool number 1 is a class 2 delay pool as in the
+# above example, and is being used to strictly limit each host to 64Kbit/sec
+# (plus overheads), with no overall limit, the line is:
+#
+# delay_parameters 1 -1/-1 8000/8000
+#
+# Note that 8 x 8000 KByte/sec -> 64Kbit/sec.
+#
+# Note that the figure -1 is used to represent "unlimited".
+#
+#
+# And, if delay pool number 2 is a class 3 delay pool as in the above
+# example, and you want to limit it to a total of 256Kbit/sec (strict limit)
+# with each 8-bit network permitted 64Kbit/sec (strict limit) and each
+# individual host permitted 4800bit/sec with a bucket maximum size of 64Kbits
+# to permit a decent web page to be downloaded at a decent speed
+# (if the network is not being limited due to overuse) but slow down
+# large downloads more significantly:
+#
+# delay_parameters 2 32000/32000 8000/8000 600/8000
+#
+# Note that 8 x 32000 KByte/sec -> 256Kbit/sec.
+# 8 x 8000 KByte/sec -> 64Kbit/sec.
+# 8 x 600 Byte/sec -> 4800bit/sec.
+#
+#
+# Finally, for a class 4 delay pool as in the example - each user will
+# be limited to 128Kbits/sec no matter how many workstations they are logged into.:
+#
+# delay_parameters 4 32000/32000 8000/8000 600/64000 16000/16000
+#Default:

+# The "standard" type does not require a wccp2_service_info option,
+# just specifying the service id will suffice.
+#
+# MD5 service authentication can be enabled by adding

+# -----------------------------------------------------------------------------
+
+# TAG: nonhierarchical_direct
+# By default, Squid will send any non-hierarchical requests

+# to origin servers.
+#
+# If you set this to off, Squid will prefer to send these
+# requests to parents.
+#
+# Note that in most configurations, by turning this off you will only
+# add latency to these request without any improvement in global hit
+# ratio.
+#
+# If you are inside an firewall see never_direct instead of
+# this directive.
+#Default:
+# nonhierarchical_direct on
+
+# TAG: prefer_direct
+# Normally Squid tries to use parents for most requests. If you for some
+# reason like it to first try going direct and only use a parent if
+# going direct fails set this to on.
+#
+# By combining nonhierarchical_direct off and prefer_direct on you
+# can set up Squid to use a parent as a backup path if going direct
+# fails.
+#
+# Note: If you want Squid to use parents for all requests see
+# the never_direct directive. prefer_direct only modifies how Squid
+# acts on cacheable requests.
+#Default:
+# prefer_direct off
+
+# TAG: always_direct
+# Usage: always_direct allow|deny [!]aclname ...
+#
+# Here you can use ACL elements to specify requests which should
+# ALWAYS be forwarded by Squid to the origin servers without using
+# any peers. For example, to always directly forward requests for
+# local servers ignoring any parents or siblings you may have use
+# something like:
+#
+# acl local-servers dstdomain my.domain.net
+# always_direct allow local-servers
+#
+# To always forward FTP requests directly, use
+#
+# acl FTP proto FTP
+# always_direct allow FTP
+#
+# NOTE: There is a similar, but opposite option named
+# 'never_direct'. You need to be aware that "always_direct deny
+# foo" is NOT the same thing as "never_direct allow foo". You
+# may need to use a deny rule to exclude a more-specific case of
+# some other rule. Example:
+#
+# acl local-external dstdomain external.foo.net
+# acl local-servers dstdomain .foo.net
+# always_direct deny local-external
+# always_direct allow local-servers

+#
+# Routing is not allowed by default: the ICAP X-Next-Services

+
+# TAG: memory_pools on|off
+# If set, Squid will keep pools of allocated (but unused) memory
+# available for future use. If memory is a premium on your
+# system and you believe your malloc library outperforms Squid
+# routines, disable this.
+#Default:
+# memory_pools on
+
+# TAG: memory_pools_limit (bytes)
+# Used only with memory_pools on:
+# memory_pools_limit 50 MB
+#
+# If set to a non-zero value, Squid will keep at most the specified
+# limit of allocated (but unused) memory in memory pools. All free()
+# requests that exceed this limit will be handled by your malloc
+# library. Squid does not pre-allocate any memory, just safe-keeps
+# objects that otherwise would be free()d. Thus, it is safe to set
+# memory_pools_limit to a reasonably high value even if your
+# configuration will use less memory.
+#
+# If set to none, Squid will keep all memory it can. That is, there
+# will be no limit on the total amount of memory used for safe-keeping.
+#
+# To disable memory allocation optimization, do not set
+# memory_pools_limit to 0 or none. Set memory_pools to "off" instead.
+#
+# An overhead for maintaining memory pools is not taken into account
+# when the limit is checked. This overhead is close to four bytes per
+# object kept. However, pools may actually _save_ memory because of
+# reduced memory thrashing in your malloc library.
+#Default:
+# memory_pools_limit 5 MB
+
+# TAG: forwarded_for on|off|transparent|truncate|delete
+# If set to "on", Squid will append your client's IP address
+# in the HTTP requests it forwards. By default it looks like:
+#
+# X-Forwarded-For: 192.1.2.3
+#
+# If set to "off", it will appear as
+#
+# X-Forwarded-For: unknown
+#
+# If set to "transparent", Squid will not alter the
+# X-Forwarded-For header in any way.
+#
+# If set to "delete", Squid will delete the entire
+# X-Forwarded-For header.
+#
+# If set to "truncate", Squid will remove all existing
+# X-Forwarded-For entries, and place itself as the sole entry.
+#Default:
+# forwarded_for on
+
+# TAG: cachemgr_passwd
+# Specify passwords for cachemgr operations.
+#
+# Usage: cachemgr_passwd password action action ...
+#
+# Some valid actions are (see cache manager menu for a full list):
+# 5min
+# 60min
+# asndb
+# authenticator
+# cbdata
+# client_list
+# comm_incoming
+# config *
+# counters
+# delay

+# storedir
+# utilization
+# via_headers
+# vm_objects
+#
+# * Indicates actions which will not be performed without a
+# valid password, others can be performed if not listed here.
+#
+# To disable an action, set the password to "disable".
+# To allow performing an action without a password, set the
+# password to "none".
+#
+# Use the keyword "all" to set the same password for all actions.
+#
+#Example:
+# cachemgr_passwd secret shutdown
+# cachemgr_passwd lesssssssecret info stats/objects
+# cachemgr_passwd disable all
+#Default:
+# none
+
+# TAG: client_db on|off
+# If you want to disable collecting per-client statistics,
+# turn off client_db here.
+#Default:
+# client_db on
+
+# TAG: refresh_all_ims on|off
+# When you enable this option, squid will always check
+# the origin server for an update when a client sends an
+# If-Modified-Since request. Many browsers use IMS
+# requests when the user requests a reload, and this
+# ensures those clients receive the latest version.
+#
+# By default (off), squid may return a Not Modified response
+# based on the age of the cached version.
+#Default:
+# refresh_all_ims off
+
+# TAG: reload_into_ims on|off
+# When you enable this option, client no-cache or ``reload''
+# requests will be changed to If-Modified-Since requests.
+# Doing this VIOLATES the HTTP standard. Enabling this
+# feature could make you liable for problems which it
+# causes.
+#
+# see also refresh_pattern for a more selective approach.
+#Default:
+# reload_into_ims off
+
+# TAG: maximum_single_addr_tries
+# This sets the maximum number of connection attempts for a
+# host that only has one address (for multiple-address hosts,
+# each address is tried once).
+#
+# The default value is one attempt, the (not recommended)
+# maximum is 255 tries. A warning message will be generated
+# if it is set to a value greater than ten.
+#
+# Note: This is in addition to the request re-forwarding which
+# takes place if Squid fails to get a satisfying response.
+#Default:
+# maximum_single_addr_tries 1
+
+# TAG: retry_on_error
+# If set to ON Squid will automatically retry requests when
+# receiving an error response with status 403 (Forbidden),
+# 500 (Internal Error), 501 or 503 (Service not available).
+# Status 502 and 504 (Gateway errors) are always retried.
+#
+# This is mainly useful if you are in a complex cache hierarchy to
+# work around access control errors.
+#
+# NOTE: This retry will attempt to find another working destination.
+# Which is different from the server which just failed.
+#Default:
+# retry_on_error off
+
+# TAG: as_whois_server
+# WHOIS server to query for AS numbers. NOTE: AS numbers are
+# queried only when Squid starts up, not for every request.
+#Default:
+# as_whois_server whois.ra.net
+
+# TAG: offline_mode
+# Enable this option and Squid will never try to validate cached
+# objects.
+#Default:
+# offline_mode off
+
+# TAG: uri_whitespace
+# What to do with requests that have whitespace characters in the
+# URI. Options:
+#
+# strip: The whitespace characters are stripped out of the URL.
+# This is the behavior recommended by RFC2396.
+# deny: The request is denied. The user receives an "Invalid
+# Request" message.
+# allow: The request is allowed and the URI is not changed. The
+# whitespace characters remain in the URI. Note the
+# whitespace is passed to redirector processes if they
+# are in use.
+# encode: The request is allowed and the whitespace characters are
+# encoded according to RFC1738. This could be considered
+# a violation of the HTTP/1.1
+# RFC because proxies are not allowed to rewrite URI's.
+# chop: The request is allowed and the URI is chopped at the
+# first whitespace. This might also be considered a
+# violation.
+#Default:
+# uri_whitespace strip
+
+# TAG: chroot
+# Specifies a directory where Squid should do a chroot() while
+# initializing. This also causes Squid to fully drop root
+# privileges after initializing. This means, for example, if you
+# use a HTTP port less than 1024 and try to reconfigure, you may
+# get an error saying that Squid can not open the port.
+#Default:
+# none
+
+# TAG: balance_on_multiple_ip
+# Modern IP resolvers in squid sort lookup results by preferred access.
+# By default squid will use these IP in order and only rotates to
+# the next listed when the most preffered fails.
+#
+# Some load balancing servers based on round robin DNS have been
+# found not to preserve user session state across requests
+# to different IP addresses.
+#
+# Enabling this directive Squid rotates IP's per request.
+#Default:
+# balance_on_multiple_ip off
+
+# TAG: pipeline_prefetch
+# To boost the performance of pipelined requests to closer
+# match that of a non-proxied environment Squid can try to fetch
+# up to two requests in parallel from a pipeline.
+#
+# Defaults to off for bandwidth management and access logging
+# reasons.
+#
+# WARNING: pipelining breaks NTLM and Negotiate/Kerberos authentication.
+#Default:
+# pipeline_prefetch off
+
+# TAG: high_response_time_warning (msec)
+# If the one-minute median response time exceeds this value,
+# Squid prints a WARNING with debug level 0 to get the
+# administrators attention. The value is in milliseconds.
+#Default:
+# high_response_time_warning 0
+
+# TAG: high_page_fault_warning
+# If the one-minute average page fault rate exceeds this
+# value, Squid prints a WARNING with debug level 0 to get
+# the administrators attention. The value is in page faults
+# per second.
+#Default:
+# high_page_fault_warning 0
+
+# TAG: high_memory_warning
+# If the memory usage (as determined by mallinfo) exceeds
+# this amount, Squid prints a WARNING with debug level 0 to get
+# the administrators attention.
+#Default:
+# high_memory_warning 0 KB
+
+# TAG: sleep_after_fork (microseconds)
+# When this is set to a non-zero value, the main Squid process
+# sleeps the specified number of microseconds after a fork()
+# system call. This sleep may help the situation where your
+# system reports fork() failures due to lack of (virtual)
+# memory. Note, however, if you have a lot of child
+# processes, these sleep delays will add up and your
+# Squid will not service requests for some amount of time
+# until all the child processes have been started.
+# On Windows value less then 1000 (1 milliseconds) are
+# rounded to 1000.
+#Default:
+# sleep_after_fork 0
+
+# TAG: windows_ipaddrchangemonitor on|off
+# On Windows Squid by default will monitor IP address changes and will
+# reconfigure itself after any detected event. This is very useful for
+# proxies connected to internet with dial-up interfaces.
+# In some cases (a Proxy server acting as VPN gateway is one) it could be
+# desiderable to disable this behaviour setting this to 'off'.
+# Note: after changing this, Squid service must be restarted.
+#Default:
+# windows_ipaddrchangemonitor on
+
+# TAG: max_filedescriptors
+# The maximum number of filedescriptors supported.
+#
+# The default "0" means Squid inherits the current ulimit setting.
+#
+# Note: Changing this requires a restart of Squid. Also
+# not all comm loops supports large values.
+#Default:
+# max_filedescriptors 0

+# WELCOME TO SQUID 3.1.20
+# ----------------------------
+#
+# This is the documentation for the Squid configuration file.
+# This documentation can also be found online at:
+# http://www.squid-cache.org/Doc/config/
+#
+# You may wish to look at the Squid home page and wiki for the
+# FAQ and other documentation:
+# http://www.squid-cache.org/
+# http://wiki.squid-cache.org/SquidFaq
+# http://wiki.squid-cache.org/ConfigExamples
+#
+# This documentation shows what the defaults for various directives
+# happen to be. If you don't need to change the default, you should
+# leave the line out of your squid.conf in most cases.
+#
+# In some cases "none" refers to no default setting at all,
+# while in other cases it refers to the value of the option
+# - the comments for that keyword indicate if this is the case.
+#
+
+# Configuration options can be included using the "include" directive.
+# Include takes a list of files to include. Quoting and wildcards are
+# supported.
+#
+# For example,
+#
+# include /path/to/included/file/squid.acl.config
+#
+# Includes can be nested up to a hard-coded depth of 16 levels.
+# This arbitrary restriction is to prevent recursive include references
+# from causing Squid entering an infinite loop whilst trying to load
+# configuration files.
+
+# TAG: dns_testnames
+# Remove this line. DNS is no longer tested on startup.
+#Default:
+# none
+
+# TAG: extension_methods
+# Remove this line. All valid methods for HTTP are accepted by default.
+#Default:
+# none
+
+# TAG: incoming_rate
+#Default:
+# none
+
+# TAG: server_http11
+# Remove this line. HTTP/1.1 is supported by default.
+#Default:
+# none
+
+# TAG: upgrade_http0.9
+# Remove this line. ICY/1.0 streaming protocol is supported by default.
+#Default:
+# none
+
+# TAG: zph_local
+# Alter these entries. Use the qos_flows directive instead.
+#Default:
+# none
+
+# TAG: header_access
+# Since squid-3.0 replace with request_header_access or reply_header_access
+# depending on whether you wish to match client requests or server replies.
+#Default:
+# none
+
+# TAG: httpd_accel_no_pmtu_disc
+# Since squid-3.0 use the 'disable-pmtu-discovery' flag on http_port instead.
+#Default:
+# none
+
+# OPTIONS FOR AUTHENTICATION
+# -----------------------------------------------------------------------------
+
+# TAG: auth_param
+# This is used to define parameters for the various authentication
+# schemes supported by Squid.
+#
+# format: auth_param scheme parameter [setting]
+#
+# The order in which authentication schemes are presented to the client is
+# dependent on the order the scheme first appears in config file. IE
+# has a bug (it's not RFC 2617 compliant) in that it will use the basic
+# scheme if basic is the first entry presented, even if more secure
+# schemes are presented. For now use the order in the recommended
+# settings section below. If other browsers have difficulties (don't
+# recognize the schemes offered even if you are using basic) either
+# put basic first, or disable the other schemes (by commenting out their
+# program entry).
+#
+# Once an authentication scheme is fully configured, it can only be
+# shutdown by shutting squid down and restarting. Changes can be made on
+# the fly and activated with a reconfigure. I.E. You can change to a
+# different helper, but not unconfigure the helper completely.
+#
+# Please note that while this directive defines how Squid processes
+# authentication it does not automatically activate authentication.
+# To use authentication you must in addition make use of ACLs based
+# on login name in http_access (proxy_auth, proxy_auth_regex or
+# external with %LOGIN used in the format tag). The browser will be
+# challenged for authentication on the first such acl encountered
+# in http_access processing and will also be re-challenged for new
+# login credentials if the request is being denied by a proxy_auth
+# type acl.
+#
+# WARNING: authentication can't be used in a transparently intercepting
+# proxy as the client then thinks it is talking to an origin server and
+# not the proxy. This is a limitation of bending the TCP/IP protocol to
+# transparently intercepting port 80, not a limitation in Squid.
+# Ports flagged 'transparent', 'intercept', or 'tproxy' have
+# authentication disabled.
+#
+# === Parameters for the basic scheme follow. ===
+#
+# "program" cmdline
+# Specify the command for the external authenticator. Such a program
+# reads a line containing "username password" and replies "OK" or
+# "ERR" in an endless loop. "ERR" responses may optionally be followed
+# by a error description available as %m in the returned error page.
+# If you use an authenticator, make sure you have 1 acl of type
+# proxy_auth.
+#
+# By default, the basic authentication scheme is not used unless a
+# program is specified.
+#
+# If you want to use the traditional NCSA proxy authentication, set
+# this line to something like
+#
+# auth_param basic program /usr/lib/squid3/ncsa_auth /usr/etc/passwd
+#
+# "utf8" on|off
+# HTTP uses iso-latin-1 as characterset, while some authentication
+# backends such as LDAP expects UTF-8. If this is set to on Squid will
+# translate the HTTP iso-latin-1 charset to UTF-8 before sending the
+# username & password to the helper.
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn. If you start too few
+# Squid will have to wait for them to process a backlog of credential
+# verifications, slowing it down. When password verifications are
+# done via a (slow) network you are likely to need lots of
+# authenticator processes.
+# auth_param basic children 5
+#
+# "concurrency" concurrency
+# The number of concurrent requests the helper can process.
+# The default of 0 is used for helpers who only supports
+# one request at a time. Setting this changes the protocol used to
+# include a channel number first on the request/response line, allowing
+# multiple requests to be sent to the same helper in parallell without
+# wating for the response.
+# Must not be set unless it's known the helper supports this.
+# auth_param basic concurrency 0
+#
+# "realm" realmstring
+# Specifies the realm name which is to be reported to the
+# client for the basic proxy authentication scheme (part of
+# the text the user will see when prompted their username and
+# password). There is no default.
+# auth_param basic realm Squid proxy-caching web server
+#
+# "credentialsttl" timetolive
+# Specifies how long squid assumes an externally validated
+# username:password pair is valid for - in other words how
+# often the helper program is called for that user. Set this
+# low to force revalidation with short lived passwords. Note
+# setting this high does not impact your susceptibility
+# to replay attacks unless you are using an one-time password
+# system (such as SecureID). If you are using such a system,
+# you will be vulnerable to replay attacks unless you also
+# use the max_user_ip ACL in an http_access rule.
+#
+# "casesensitive" on|off
+# Specifies if usernames are case sensitive. Most user databases are
+# case insensitive allowing the same username to be spelled using both
+# lower and upper case letters, but some are case sensitive. This
+# makes a big difference for user_max_ip ACL processing and similar.
+# auth_param basic casesensitive off
+#
+# === Parameters for the digest scheme follow ===
+#
+# "program" cmdline
+# Specify the command for the external authenticator. Such
+# a program reads a line containing "username":"realm" and
+# replies with the appropriate H(A1) value hex encoded or
+# ERR if the user (or his H(A1) hash) does not exists.
+# See rfc 2616 for the definition of H(A1).
+# "ERR" responses may optionally be followed by a error description
+# available as %m in the returned error page.
+#
+# By default, the digest authentication scheme is not used unless a
+# program is specified.
+#
+# If you want to use a digest authenticator, set this line to
+# something like
+#
+# auth_param digest program /usr/lib/squid3/digest_pw_auth /usr/etc/digpass
+#
+# "utf8" on|off
+# HTTP uses iso-latin-1 as characterset, while some authentication

+# translate the HTTP iso-latin-1 charset to UTF-8 before sending the
+# username & password to the helper.
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to
+# process a backlog of H(A1) calculations, slowing it down.
+# When the H(A1) calculations are done via a (slow) network
+# you are likely to need lots of authenticator processes.
+# auth_param digest children 5
+#
+# "realm" realmstring
+# Specifies the realm name which is to be reported to the
+# client for the digest proxy authentication scheme (part of
+# the text the user will see when prompted their username and
+# password). There is no default.
+# auth_param digest realm Squid proxy-caching web server
+#
+# "nonce_garbage_interval" timeinterval
+# Specifies the interval that nonces that have been issued
+# to client_agent's are checked for validity.
+#
+# "nonce_max_duration" timeinterval
+# Specifies the maximum length of time a given nonce will be
+# valid for.
+#
+# "nonce_max_count" number
+# Specifies the maximum number of times a given nonce can be
+# used.
+#
+# "nonce_strictness" on|off
+# Determines if squid requires strict increment-by-1 behavior
+# for nonce counts, or just incrementing (off - for use when
+# useragents generate nonce counts that occasionally miss 1
+# (ie, 1,2,4,6)). Default off.
+#
+# "check_nonce_count" on|off
+# This directive if set to off can disable the nonce count check
+# completely to work around buggy digest qop implementations in
+# certain mainstream browser versions. Default on to check the
+# nonce count to protect from authentication replay attacks.
+#
+# "post_workaround" on|off
+# This is a workaround to certain buggy browsers who sends
+# an incorrect request digest in POST requests when reusing
+# the same nonce as acquired earlier on a GET request.
+#
+# === NTLM scheme options follow ===
+#
+# "program" cmdline
+# Specify the command for the external NTLM authenticator.
+# Such a program reads exchanged NTLMSSP packets with
+# the browser via Squid until authentication is completed.
+# If you use an NTLM authenticator, make sure you have 1 acl
+# of type proxy_auth. By default, the NTLM authenticator_program
+# is not used.
+#
+# auth_param ntlm program /usr/lib/squid3/ntlm_auth
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to
+# process a backlog of credential verifications, slowing it
+# down. When credential verifications are done via a (slow)
+# network you are likely to need lots of authenticator
+# processes.
+#
+# auth_param ntlm children 5
+#
+# "keep_alive" on|off
+# Whether to keep the connection open after the initial response where
+# Squid tells the browser which schemes are supported by the proxy.
+# Some browsers are known to present many login popups or to corrupt
+# POST/PUT requests transfer if the connection is not closed.
+# The default is currently OFF to avoid this, but may change.
+#
+# auth_param ntlm keep_alive on
+#
+# === Options for configuring the NEGOTIATE auth-scheme follow ===
+#
+# "program" cmdline
+# Specify the command for the external Negotiate authenticator.
+# This protocol is used in Microsoft Active-Directory enabled setups with
+# the Microsoft Internet Explorer or Mozilla Firefox browsers.
+# Its main purpose is to exchange credentials with the Squid proxy
+# using the Kerberos mechanisms.
+# If you use a Negotiate authenticator, make sure you have at least

+# an additional ACL needs to be used which ensures the IPv6-bound traffic

+# OPTIONS WHICH AFFECT THE NEIGHBOR SELECTION ALGORITHM
+# -----------------------------------------------------------------------------
+
+# TAG: cache_peer
+# To specify other caches in a hierarchy, use the format:
+#
+# cache_peer hostname type http-port icp-port [options]
+#
+# For example,
+#
+# # proxy icp
+# # hostname type port port options
+# # -------------------- -------- ----- ----- -----------
+# cache_peer parent.foo.net parent 3128 3130 default
+# cache_peer sib1.foo.net sibling 3128 3130 proxy-only
+# cache_peer sib2.foo.net sibling 3128 3130 proxy-only
+# cache_peer example.com parent 80 0 default
+# cache_peer cdn.example.com sibling 3128 0
+#
+# type: either 'parent', 'sibling', or 'multicast'.
+#
+# proxy-port: The port number where the peer accept HTTP requests.
+# For other Squid proxies this is usually 3128
+# For web servers this is usually 80
+#
+# icp-port: Used for querying neighbor caches about objects.
+# Set to 0 if the peer does not support ICP or HTCP.
+# See ICP and HTCP options below for additional details.
+#
+#
+# ==== ICP OPTIONS ====
+#
+# You MUST also set icp_port and icp_access explicitly when using these options.
+# The defaults will prevent peer traffic using ICP.
+#
+#
+# no-query Disable ICP queries to this neighbor.
+#
+# multicast-responder
+# Indicates the named peer is a member of a multicast group.
+# ICP queries will not be sent directly to the peer, but ICP
+# replies will be accepted from it.
+#
+# closest-only Indicates that, for ICP_OP_MISS replies, we'll only forward
+# CLOSEST_PARENT_MISSes and never FIRST_PARENT_MISSes.
+#
+# background-ping
+# To only send ICP queries to this neighbor infrequently.
+# This is used to keep the neighbor round trip time updated
+# and is usually used in conjunction with weighted-round-robin.
+#
+#
+# ==== HTCP OPTIONS ====
+#
+# You MUST also set htcp_port and htcp_access explicitly when using these options.
+# The defaults will prevent peer traffic using HTCP.
+#
+#
+# htcp Send HTCP, instead of ICP, queries to the neighbor.
+# You probably also want to set the "icp-port" to 4827
+# instead of 3130.
+#
+# htcp-oldsquid Send HTCP to old Squid versions.
+#
+# htcp-no-clr Send HTCP to the neighbor but without
+# sending any CLR requests. This cannot be used with
+# htcp-only-clr.
+#
+# htcp-only-clr Send HTCP to the neighbor but ONLY CLR requests.
+# This cannot be used with htcp-no-clr.
+#
+# htcp-no-purge-clr
+# Send HTCP to the neighbor including CLRs but only when
+# they do not result from PURGE requests.
+#
+# htcp-forward-clr
+# Forward any HTCP CLR requests this proxy receives to the peer.
+#
+#
+# ==== PEER SELECTION METHODS ====
+#
+# The default peer selection method is ICP, with the first responding peer
+# being used as source. These options can be used for better load balancing.
+#
+#
+# default This is a parent cache which can be used as a "last-resort"
+# if a peer cannot be located by any of the peer-selection methods.
+# If specified more than once, only the first is used.
+#
+# round-robin Load-Balance parents which should be used in a round-robin
+# fashion in the absence of any ICP queries.
+# weight=N can be used to add bias.
+#
+# weighted-round-robin
+# Load-Balance parents which should be used in a round-robin
+# fashion with the frequency of each parent being based on the
+# round trip time. Closer parents are used more often.
+# Usually used for background-ping parents.
+# weight=N can be used to add bias.
+#
+# carp Load-Balance parents which should be used as a CARP array.
+# The requests will be distributed among the parents based on the
+# CARP load balancing hash function based on their weight.
+#
+# userhash Load-balance parents based on the client proxy_auth or ident username.
+#
+# sourcehash Load-balance parents based on the client source IP.
+#
+# multicast-siblings
+# To be used only for cache peers of type "multicast".
+# ALL members of this multicast group have "sibling"
+# relationship with it, not "parent". This is to a multicast
+# group when the requested object would be fetched only from
+# a "parent" cache, anyway. It's useful, e.g., when
+# configuring a pool of redundant Squid proxies, being
+# members of the same multicast group.
+#
+#
+# ==== PEER SELECTION OPTIONS ====
+#
+# weight=N use to affect the selection of a peer during any weighted
+# peer-selection mechanisms.
+# The weight must be an integer; default is 1,
+# larger weights are favored more.
+# This option does not affect parent selection if a peering
+# protocol is not in use.
+#
+# basetime=N Specify a base amount to be subtracted from round trip
+# times of parents.
+# It is subtracted before division by weight in calculating
+# which parent to fectch from. If the rtt is less than the
+# base time the rtt is set to a minimal value.
+#
+# ttl=N Specify a TTL to use when sending multicast ICP queries
+# to this address.
+# Only useful when sending to a multicast group.
+# Because we don't accept ICP replies from random
+# hosts, you must configure other group members as
+# peers with the 'multicast-responder' option.
+#
+# no-delay To prevent access to this neighbor from influencing the
+# delay pools.
+#
+# digest-url=URL Tell Squid to fetch the cache digest (if digests are
+# enabled) for this host from the specified URL rather
+# than the Squid default location.
+#
+#
+# ==== ACCELERATOR / REVERSE-PROXY OPTIONS ====
+#
+# originserver Causes this parent to be contacted as an origin server.
+# Meant to be used in accelerator setups when the peer
+# is a web server.
+#
+# forceddomain=name
+# Set the Host header of requests forwarded to this peer.
+# Useful in accelerator setups where the server (peer)
+# expects a certain domain name but clients may request
+# others. ie example.com or www.example.com
+#
+# no-digest Disable request of cache digests.
+#
+# no-netdb-exchange
+# Disables requesting ICMP RTT database (NetDB).
+#
+#
+# ==== AUTHENTICATION OPTIONS ====
+#
+# login=user:password
+# If this is a personal/workgroup proxy and your parent
+# requires proxy authentication.
+#
+# Note: The string can include URL escapes (i.e. %20 for
+# spaces). This also means % must be written as %%.
+#
+# login=PROXYPASS
+# Send login details received from client to this peer.
+# Authentication is not required, nor changed.
+#
+# Note: This will pass any form of authentication but
+# only Basic auth will work through a proxy unless the
+# connection-auth options are also used.
+#
+# login=PASS Send login details received from client to this peer.
+# Authentication is not required by this option.
+# If there are no client-provided authentication headers
+# to pass on, but username and password are available
+# from either proxy login or an external ACL user= and
+# password= result tags they may be sent instead.
+#
+# Note: To combine this with proxy_auth both proxies must
+# share the same user database as HTTP only allows for
+# a single login (one for proxy, one for origin server).
+# Also be warned this will expose your users proxy
+# password to the peer. USE WITH CAUTION
+#
+# login=*:password
+# Send the username to the upstream cache, but with a
+# fixed password. This is meant to be used when the peer
+# is in another administrative domain, but it is still
+# needed to identify each user.
+# The star can optionally be followed by some extra
+# information which is added to the username. This can
+# be used to identify this proxy to the peer, similar to
+# the login=username:password option above.
+#
+# connection-auth=on|off
+# Tell Squid that this peer does or not support Microsoft
+# connection oriented authentication, and any such
+# challenges received from there should be ignored.
+# Default is auto to automatically determine the status
+# of the peer.
+#
+#
+# ==== SSL / HTTPS / TLS OPTIONS ====
+#
+# ssl Encrypt connections to this peer with SSL/TLS.
+#
+# sslcert=/path/to/ssl/certificate
+# A client SSL certificate to use when connecting to
+# this peer.
+#
+# sslkey=/path/to/ssl/key
+# The private SSL key corresponding to sslcert above.
+# If 'sslkey' is not specified 'sslcert' is assumed to
+# reference a combined file containing both the
+# certificate and the key.
+#
+# sslversion=1|2|3|4
+# The SSL version to use when connecting to this peer
+# 1 = automatic (default)
+# 2 = SSL v2 only
+# 3 = SSL v3 only
+# 4 = TLS v1 only
+#
+# sslcipher=... The list of valid SSL ciphers to use when connecting
+# to this peer.
+#
+# ssloptions=... Specify various SSL engine options:
+# NO_SSLv2 Disallow the use of SSLv2
+# NO_SSLv3 Disallow the use of SSLv3
+# NO_TLSv1 Disallow the use of TLSv1
+# See src/ssl_support.c or the OpenSSL documentation for
+# a more complete list.
+#
+# sslcafile=... A file containing additional CA certificates to use
+# when verifying the peer certificate.
+#
+# sslcapath=... A directory containing additional CA certificates to
+# use when verifying the peer certificate.
+#
+# sslcrlfile=... A certificate revocation list file to use when
+# verifying the peer certificate.
+#
+# sslflags=... Specify various flags modifying the SSL implementation:
+#
+# DONT_VERIFY_PEER
+# Accept certificates even if they fail to
+# verify.
+# NO_DEFAULT_CA
+# Don't use the default CA list built in
+# to OpenSSL.
+# DONT_VERIFY_DOMAIN
+# Don't verify the peer certificate
+# matches the server name
+#
+# ssldomain= The peer name as advertised in it's certificate.
+# Used for verifying the correctness of the received peer
+# certificate. If not specified the peer hostname will be
+# used.
+#
+# front-end-https
+# Enable the "Front-End-Https: On" header needed when
+# using Squid as a SSL frontend in front of Microsoft OWA.
+# See MS KB document Q307347 for details on this header.
+# If set to auto the header will only be added if the
+# request is forwarded as a https:// URL.
+#
+#
+# ==== GENERAL OPTIONS ====
+#
+# connect-timeout=N
+# A peer-specific connect timeout.
+# Also see the peer_connect_timeout directive.
+#
+# connect-fail-limit=N
+# How many times connecting to a peer must fail before
+# it is marked as down. Default is 10.
+#
+# allow-miss Disable Squid's use of only-if-cached when forwarding
+# requests to siblings. This is primarily useful when
+# icp_hit_stale is used by the sibling. To extensive use
+# of this option may result in forwarding loops, and you
+# should avoid having two-way peerings with this option.
+# For example to deny peer usage on requests from peer
+# by denying cache_peer_access if the source is a peer.
+#
+# max-conn=N Limit the amount of connections Squid may open to this
+# peer. see also
+#
+# name=xxx Unique name for the peer.
+# Required if you have multiple peers on the same host
+# but different ports.
+# This name can be used in cache_peer_access and similar
+# directives to dentify the peer.
+# Can be used by outgoing access controls through the
+# peername ACL type.
+#
+# no-tproxy Do not use the client-spoof TPROXY support when forwarding
+# requests to this peer. Use normal address selection instead.
+#
+# proxy-only objects fetched from the peer will not be stored locally.
+#
+#Default:
+# none
+
+# TAG: cache_peer_domain
+# Use to limit the domains for which a neighbor cache will be
+# queried. Usage:
+#
+# cache_peer_domain cache-host domain [domain ...]
+# cache_peer_domain cache-host !domain
+#
+# For example, specifying
+#
+# cache_peer_domain parent.foo.net .edu
+#
+# has the effect such that UDP query packets are sent to
+# 'bigserver' only when the requested object exists on a
+# server in the .edu domain. Prefixing the domainname
+# with '!' means the cache will be queried for objects
+# NOT in that domain.
+#
+# NOTE: * Any number of domains may be given for a cache-host,
+# either on the same or separate lines.
+# * When multiple domains are given for a particular
+# cache-host, the first matched domain is applied.
+# * Cache hosts with no domain restrictions are queried
+# for all requests.
+# * There are no defaults.
+# * There is also a 'cache_peer_access' tag in the ACL
+# section.
+#Default:
+# none
+
+# TAG: cache_peer_access
+# Similar to 'cache_peer_domain' but provides more flexibility by
+# using ACL elements.
+#
+# cache_peer_access cache-host allow|deny [!]aclname ...
+#
+# The syntax is identical to 'http_access' and the other lists of
+# ACL elements. See the comments for 'http_access' below, or
+# the Squid FAQ (http://wiki.squid-cache.org/SquidFaq/SquidAcl).
+#Default:
+# none
+
+# TAG: neighbor_type_domain
+# usage: neighbor_type_domain neighbor parent|sibling domain domain ...
+#
+# Modifying the neighbor type for specific domains is now
+# possible. You can treat some domains differently than the the
+# default neighbor type specified on the 'cache_peer' line.
+# Normally it should only be necessary to list domains which
+# should be treated differently because the default neighbor type
+# applies for hostnames which do not match domains listed here.
+#
+#EXAMPLE:
+# cache_peer cache.foo.org parent 3128 3130
+# neighbor_type_domain cache.foo.org sibling .com .net
+# neighbor_type_domain cache.foo.org sibling .au .de
+#Default:
+# none
+
+# TAG: dead_peer_timeout (seconds)
+# This controls how long Squid waits to declare a peer cache
+# as "dead." If there are no ICP replies received in this
+# amount of time, Squid will declare the peer dead and not
+# expect to receive any further ICP replies. However, it
+# continues to send ICP queries, and will mark the peer as
+# alive upon receipt of the first subsequent ICP reply.
+#
+# This timeout also affects when Squid expects to receive ICP
+# replies from peers. If more than 'dead_peer' seconds have
+# passed since the last ICP reply was received, Squid will not
+# expect to receive an ICP reply on the next query. Thus, if
+# your time between requests is greater than this timeout, you
+# will see a lot of requests sent DIRECT to origin servers
+# instead of to your parents.
+#Default:
+# dead_peer_timeout 10 seconds
+
+# TAG: forward_max_tries
+# Controls how many different forward paths Squid will try
+# before giving up. See also forward_timeout.
+#Default:
+# forward_max_tries 10
+
+# TAG: hierarchy_stoplist
+# A list of words which, if found in a URL, cause the object to
+# be handled directly by this cache. In other words, use this
+# to not query neighbor caches for certain objects. You may
+# list this option multiple times.
+#
+# Example:
+# hierarchy_stoplist cgi-bin ?
+#
+# Note: never_direct overrides this option.
+#Default:
+# none
+
+# MEMORY CACHE OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: cache_mem (bytes)
+# NOTE: THIS PARAMETER DOES NOT SPECIFY THE MAXIMUM PROCESS SIZE.
+# IT ONLY PLACES A LIMIT ON HOW MUCH ADDITIONAL MEMORY SQUID WILL
+# USE AS A MEMORY CACHE OF OBJECTS. SQUID USES MEMORY FOR OTHER
+# THINGS AS WELL. SEE THE SQUID FAQ SECTION 8 FOR DETAILS.
+#
+# 'cache_mem' specifies the ideal amount of memory to be used
+# for:
+# * In-Transit objects
+# * Hot Objects
+# * Negative-Cached objects
+#
+# Data for these objects are stored in 4 KB blocks. This
+# parameter specifies the ideal upper limit on the total size of
+# 4 KB blocks allocated. In-Transit objects take the highest
+# priority.
+#
+# In-transit objects have priority over the others. When
+# additional space is needed for incoming data, negative-cached
+# and hot objects will be released. In other words, the
+# negative-cached and hot objects will fill up any unused space
+# not needed for in-transit objects.
+#
+# If circumstances require, this limit will be exceeded.
+# Specifically, if your incoming request rate requires more than
+# 'cache_mem' of memory to hold in-transit objects, Squid will
+# exceed this limit to satisfy the new requests. When the load
+# decreases, blocks will be freed until the high-water mark is
+# reached. Thereafter, blocks will be used to store hot
+# objects.
+#Default:
+# cache_mem 256 MB
+
+# TAG: maximum_object_size_in_memory (bytes)
+# Objects greater than this size will not be attempted to kept in
+# the memory cache. This should be set high enough to keep objects
+# accessed frequently in memory to improve performance whilst low
+# enough to keep larger objects from hoarding cache_mem.
+#Default:
+# maximum_object_size_in_memory 512 KB
+
+# TAG: memory_replacement_policy
+# The memory replacement policy parameter determines which
+# objects are purged from memory when memory space is needed.
+#
+# See cache_replacement_policy for details.
+#Default:
+# memory_replacement_policy lru
+
+# DISK CACHE OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: cache_replacement_policy
+# The cache replacement policy parameter determines which
+# objects are evicted (replaced) when disk space is needed.
+#
+# lru : Squid's original list based LRU policy
+# heap GDSF : Greedy-Dual Size Frequency
+# heap LFUDA: Least Frequently Used with Dynamic Aging
+# heap LRU : LRU policy implemented using a heap
+#
+# Applies to any cache_dir lines listed below this.
+#
+# The LRU policies keeps recently referenced objects.
+#
+# The heap GDSF policy optimizes object hit rate by keeping smaller
+# popular objects in cache so it has a better chance of getting a
+# hit. It achieves a lower byte hit rate than LFUDA though since
+# it evicts larger (possibly popular) objects.
+#
+# The heap LFUDA policy keeps popular objects in cache regardless of
+# their size and thus optimizes byte hit rate at the expense of
+# hit rate since one large, popular object will prevent many
+# smaller, slightly less popular objects from being cached.
+#
+# Both policies utilize a dynamic aging mechanism that prevents
+# cache pollution that can otherwise occur with frequency-based
+# replacement policies.
+#
+# NOTE: if using the LFUDA replacement policy you should increase
+# the value of maximum_object_size above its default of 4096 KB to
+# to maximize the potential byte hit rate improvement of LFUDA.

+# Q1 specifies the number of unacknowledged I/O requests when Squid
+# stops opening new files. If this many messages are in the queues,
+# Squid won't open new files. Default is 64
+#
+# Q2 specifies the number of unacknowledged messages when Squid
+# starts blocking. If this many messages are in the queues,
+# Squid blocks until it receives some replies. Default is 72
+#
+# When Q1 < Q2 (the default), the cache directory is optimized

+#
+# block-size=n defines the "block size" for COSS cache_dir's.
+# Squid uses file numbers as block numbers. Since file numbers
+# are limited to 24 bits, the block size determines the maximum
+# size of the COSS partition. The default is 512 bytes, which
+# leads to a maximum cache_dir size of 512<<24, or 8 GB. Note
+# you should not change the coss block size after Squid
+# has written some objects to the cache_dir.
+#
+# The coss file store has changed from 2.5. Now it uses a file
+# called 'stripe' in the directory names in the config - and
+# this will be created by squid -z.
+#
+# Common options:
+#
+# no-store, no new objects should be stored to this cache_dir
+#
+# max-size=n, refers to the max object size in bytes this cache_dir
+# supports. It is used to select the cache_dir to store the object.
+# Note: To make optimal use of the max-size limits you should order
+# the cache_dir lines with the smallest max-size value first and the
+# ones with no max-size specification last.
+#
+# Note for coss, max-size must be less than COSS_MEMBUF_SZ,
+# which can be changed with the --with-coss-membuf-size=N configure
+# option.

+#
+# If adaptation is enabled the following two codes become available:

+# adapt::all_trs.
+#
+# adapt::all_trs All adaptation transaction response times.
+# Same as adaptation_strs but response times of
+# individual transactions are never added

+#
+# ICAP log uses logformat codes that make sense for an ICAP

+# For REQMOD, there is no HTTP response header unless the ICAP
+# server performed request satisfaction. For RESPMOD, the HTTP
+# request header is the header sent to the ICAP server. For
+# OPTIONS, there are no HTTP headers.
+#
+# The following format codes are also available for ICAP logs:
+#
+# icap::<A ICAP server IP address. Similar to <A.
+#
+# icap::<service_name ICAP service name from the icap_service
+# option in Squid configuration file.
+#
+# icap::ru ICAP Request-URI. Similar to ru.

+#
+# icap::<st Bytes received from the ICAP server (TCP

+#
+# icap::tr Transaction response time (in
+# milliseconds). The timer starts when
+# the ICAP transaction is created and
+# stops when the transaction is completed.
+# Similar to tr.
+#
+# icap::tio Transaction I/O time (in milliseconds). The
+# timer starts when the first ICAP request
+# byte is scheduled for sending. The timers
+# stops when the last byte of the ICAP response
+# is received.
+#
+# icap::to Transaction outcome: ICAP_ERR* for all
+# transaction errors, ICAP_OPT for OPTION
+# transactions, ICAP_ECHO for 204

+
+# TAG: cache_swap_state
+# Location for the cache "swap.state" file. This index file holds
+# the metadata of objects saved on disk. It is used to rebuild

+# a directory. Since this is the index for the whole object
+# list you CANNOT periodically rotate it!
+#
+# If %s can be used in the file name it will be replaced with a
+# a representation of the cache_dir name where each / is replaced

+
+# TAG: logfile_rotate
+# Specifies the number of logfile rotations to make when you

+# with extensions 0 through 9. Setting logfile_rotate to 0 will
+# disable the file name rotation, but the logfiles are still closed
+# and re-opened. This will enable you to rename the logfiles
+# yourself just before sending the rotate signal.
+#
+# Note, the 'squid -k rotate' command normally sends a USR1
+# signal to the running squid process. In certain situations
+# (e.g. on Linux with Async I/O), USR1 is used for other
+# purposes, so -k rotate uses another signal. It is best to get
+# in the habit of using 'squid -k rotate' instead of 'kill -USR1
+# <pid>'.
+#
+# Note, from Squid-3.1 this option has no effect on the cache.log,

+#Default:
+# relaxed_header_parser on
+
+# TAG: ignore_expect_100 on|off
+# This option makes Squid ignore any Expect: 100-continue header present
+# in the request. RFC 2616 requires that Squid being unable to satisfy

+
+# TIMEOUTS
+# -----------------------------------------------------------------------------
+
+# TAG: forward_timeout time-units
+# This parameter specifies how long Squid should at most attempt in
+# finding a forwarding path for the request before giving up.
+#Default:
+# forward_timeout 4 minutes
+
+# TAG: connect_timeout time-units
+# This parameter specifies how long to wait for the TCP connect to
+# the requested server or peer to complete before Squid should
+# attempt to find another path where to forward the request.
+#Default:
+# connect_timeout 1 minute
+
+# TAG: peer_connect_timeout time-units
+# This parameter specifies how long to wait for a pending TCP
+# connection to a peer cache. The default is 30 seconds. You
+# may also set different timeout values for individual neighbors
+# with the 'connect-timeout' option on a 'cache_peer' line.
+#Default:
+# peer_connect_timeout 30 seconds
+
+# TAG: read_timeout time-units
+# The read_timeout is applied on server-side connections. After
+# each successful read(), the timeout will be extended by this
+# amount. If no data is read again after this amount of time,
+# the request is aborted and logged with ERR_READ_TIMEOUT. The
+# default is 15 minutes.
+#Default:

+#Default:
+# persistent_request_timeout 2 minutes
+
+# TAG: client_lifetime time-units
+# The maximum amount of time a client (browser) is allowed to
+# remain connected to the cache process. This protects the Cache
+# from having a lot of sockets (and hence file descriptors) tied up
+# in a CLOSE_WAIT state from remote clients that go away without
+# properly shutting down (either because of a network failure or
+# because of a poor client implementation). The default is one
+# day, 1440 minutes.
+#
+# NOTE: The default value is intended to be much larger than any
+# client would ever need to be connected to your cache. You
+# should probably change client_lifetime only as a last resort.
+# If you seem to have many client connections tying up
+# filedescriptors, we recommend first tuning the read_timeout,

+#Default:
+# client_lifetime 1 day
+
+# TAG: half_closed_clients
+# Some clients may shutdown the sending side of their TCP
+# connections, while leaving their receiving sides open. Sometimes,
+# Squid can not tell the difference between a half-closed and a
+# fully-closed TCP connection.
+#
+# By default, Squid will immediately close client connections when
+# read(2) returns "no more data to read."
+#
+# Change this option to 'on' and Squid will keep open connections
+# until a read(2) or write(2) on the socket returns an error.
+# This may show some benefits for reverse proxies. But if not

+
+# DELAY POOL PARAMETERS
+# -----------------------------------------------------------------------------
+
+# TAG: delay_pools
+# This represents the number of delay pools to be used. For example,
+# if you have one class 2 delay pool and one class 3 delays pool, you
+# have a total of 2 delay pools.
+#Default:
+# delay_pools 0
+
+# TAG: delay_class
+# This defines the class of each delay pool. There must be exactly one
+# delay_class line for each delay pool. For example, to define two
+# delay pools, one of class 2 and one of class 3, the settings above
+# and here would be:
+#
+# Example:
+# delay_pools 4 # 4 delay pools
+# delay_class 1 2 # pool 1 is a class 2 pool
+# delay_class 2 3 # pool 2 is a class 3 pool
+# delay_class 3 4 # pool 3 is a class 4 pool
+# delay_class 4 5 # pool 4 is a class 5 pool
+#
+# The delay pool classes are:
+#
+# class 1 Everything is limited by a single aggregate
+# bucket.
+#
+# class 2 Everything is limited by a single aggregate
+# bucket as well as an "individual" bucket chosen
+# from bits 25 through 32 of the IPv4 address.
+#
+# class 3 Everything is limited by a single aggregate
+# bucket as well as a "network" bucket chosen
+# from bits 17 through 24 of the IP address and a
+# "individual" bucket chosen from bits 17 through
+# 32 of the IPv4 address.
+#
+# class 4 Everything in a class 3 delay pool, with an
+# additional limit on a per user basis. This
+# only takes effect if the username is established
+# in advance - by forcing authentication in your
+# http_access rules.
+#
+# class 5 Requests are grouped according their tag (see
+# external_acl's tag= reply).
+#
+#
+# Each pool also requires a delay_parameters directive to configure the pool size
+# and speed limits used whenever the pool is applied to a request. Along with
+# a set of delay_access directives to determine when it is used.
+#
+# NOTE: If an IP address is a.b.c.d
+# -> bits 25 through 32 are "d"
+# -> bits 17 through 24 are "c"
+# -> bits 17 through 32 are "c * 256 + d"
+#
+# NOTE-2: Due to the use of bitmasks in class 2,3,4 pools they only apply to
+# IPv4 traffic. Class 1 and 5 pools may be used with IPv6 traffic.
+#Default:
+# none
+
+# TAG: delay_access
+# This is used to determine which delay pool a request falls into.
+#
+# delay_access is sorted per pool and the matching starts with pool 1,
+# then pool 2, ..., and finally pool N. The first delay pool where the
+# request is allowed is selected for the request. If it does not allow
+# the request to any pool then the request is not delayed (default).
+#
+# For example, if you want some_big_clients in delay
+# pool 1 and lotsa_little_clients in delay pool 2:
+#
+#Example:
+# delay_access 1 allow some_big_clients
+# delay_access 1 deny all
+# delay_access 2 allow lotsa_little_clients
+# delay_access 2 deny all
+# delay_access 3 allow authenticated_clients
+#Default:
+# none
+
+# TAG: delay_parameters
+# This defines the parameters for a delay pool. Each delay pool has
+# a number of "buckets" associated with it, as explained in the
+# description of delay_class.
+#
+# For a class 1 delay pool, the syntax is:
+# delay_pools pool 1
+# delay_parameters pool aggregate
+#
+# For a class 2 delay pool:
+# delay_pools pool 2
+# delay_parameters pool aggregate individual
+#
+# For a class 3 delay pool:
+# delay_pools pool 3
+# delay_parameters pool aggregate network individual
+#
+# For a class 4 delay pool:
+# delay_pools pool 4
+# delay_parameters pool aggregate network individual user
+#
+# For a class 5 delay pool:
+# delay_pools pool 5
+# delay_parameters pool tagrate
+#
+# The option variables are:
+#
+# pool a pool number - ie, a number between 1 and the
+# number specified in delay_pools as used in
+# delay_class lines.
+#
+# aggregate the speed limit parameters for the aggregate bucket
+# (class 1, 2, 3).
+#
+# individual the speed limit parameters for the individual
+# buckets (class 2, 3).
+#
+# network the speed limit parameters for the network buckets
+# (class 3).
+#
+# user the speed limit parameters for the user buckets
+# (class 4).
+#
+# tagrate the speed limit parameters for the tag buckets
+# (class 5).
+#
+# A pair of delay parameters is written restore/maximum, where restore is
+# the number of bytes (not bits - modem and network speeds are usually
+# quoted in bits) per second placed into the bucket, and maximum is the
+# maximum number of bytes which can be in the bucket at any time.
+#
+# There must be one delay_parameters line for each delay pool.
+#
+#
+# For example, if delay pool number 1 is a class 2 delay pool as in the
+# above example, and is being used to strictly limit each host to 64Kbit/sec
+# (plus overheads), with no overall limit, the line is:
+#
+# delay_parameters 1 -1/-1 8000/8000
+#
+# Note that 8 x 8000 KByte/sec -> 64Kbit/sec.
+#
+# Note that the figure -1 is used to represent "unlimited".
+#
+#
+# And, if delay pool number 2 is a class 3 delay pool as in the above
+# example, and you want to limit it to a total of 256Kbit/sec (strict limit)
+# with each 8-bit network permitted 64Kbit/sec (strict limit) and each
+# individual host permitted 4800bit/sec with a bucket maximum size of 64Kbits
+# to permit a decent web page to be downloaded at a decent speed
+# (if the network is not being limited due to overuse) but slow down
+# large downloads more significantly:
+#
+# delay_parameters 2 32000/32000 8000/8000 600/8000
+#
+# Note that 8 x 32000 KByte/sec -> 256Kbit/sec.
+# 8 x 8000 KByte/sec -> 64Kbit/sec.
+# 8 x 600 Byte/sec -> 4800bit/sec.
+#
+#
+# Finally, for a class 4 delay pool as in the example - each user will
+# be limited to 128Kbits/sec no matter how many workstations they are logged into.:
+#
+# delay_parameters 4 32000/32000 8000/8000 600/64000 16000/16000
+#Default:
+# none
+
+# TAG: delay_initial_bucket_level (percent, 0-100)
+# The initial bucket percentage is used to determine how much is put
+# in each bucket when squid starts, is reconfigured, or first notices
+# a host accessing it (in class 2 and class 3, individual hosts and
+# networks only have buckets associated with them once they have been
+# "seen" by squid).

+# to origin servers.
+#
+# If you set this to off, Squid will prefer to send these
+# requests to parents.
+#
+# Note that in most configurations, by turning this off you will only
+# add latency to these request without any improvement in global hit
+# ratio.
+#
+# If you are inside an firewall see never_direct instead of
+# this directive.
+#Default:
+# nonhierarchical_direct on
+
+# TAG: prefer_direct
+# Normally Squid tries to use parents for most requests. If you for some
+# reason like it to first try going direct and only use a parent if
+# going direct fails set this to on.
+#
+# By combining nonhierarchical_direct off and prefer_direct on you
+# can set up Squid to use a parent as a backup path if going direct
+# fails.
+#
+# Note: If you want Squid to use parents for all requests see
+# the never_direct directive. prefer_direct only modifies how Squid
+# acts on cacheable requests.
+#Default:
+# prefer_direct off
+
+# TAG: always_direct
+# Usage: always_direct allow|deny [!]aclname ...
+#
+# Here you can use ACL elements to specify requests which should
+# ALWAYS be forwarded by Squid to the origin servers without using
+# any peers. For example, to always directly forward requests for
+# local servers ignoring any parents or siblings you may have use
+# something like:
+#
+# acl local-servers dstdomain my.domain.net
+# always_direct allow local-servers
+#
+# To always forward FTP requests directly, use
+#
+# acl FTP proto FTP
+# always_direct allow FTP
+#
+# NOTE: There is a similar, but opposite option named
+# 'never_direct'. You need to be aware that "always_direct deny
+# foo" is NOT the same thing as "never_direct allow foo". You
+# may need to use a deny rule to exclude a more-specific case of
+# some other rule. Example:
+#
+# acl local-external dstdomain external.foo.net
+# acl local-servers dstdomain .foo.net
+# always_direct deny local-external
+# always_direct allow local-servers
+#
+# NOTE: If your goal is to make the client forward the request
+# directly to the origin server bypassing Squid then this needs
+# to be done in the client configuration. Squid configuration
+# can only tell Squid how Squid should fetch the object.
+#
+# NOTE: This directive is not related to caching. The replies
+# is cached as usual even if you use always_direct. To not cache
+# the replies see the 'cache' directive.
+#
+# This clause supports both fast and slow acl types.
+# See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
+#Default:
+# none
+
+# TAG: never_direct
+# Usage: never_direct allow|deny [!]aclname ...
+#
+# never_direct is the opposite of always_direct. Please read
+# the description for always_direct if you have not already.
+#
+# With 'never_direct' you can use ACL elements to specify
+# requests which should NEVER be forwarded directly to origin
+# servers. For example, to force the use of a proxy for all
+# requests, except those in your local domain use something like:
+#
+# acl local-servers dstdomain .foo.net
+# never_direct deny local-servers
+# never_direct allow all
+#
+# or if Squid is inside a firewall and there are local intranet
+# servers inside the firewall use something like:
+#
+# acl local-intranet dstdomain .foo.net
+# acl local-external dstdomain external.foo.net
+# always_direct deny local-external
+# always_direct allow local-intranet
+# never_direct allow all

+# Defines a single ICAP service using the following format:
+#
+# icap_service service_name vectoring_point [options] service_url
+#
+# service_name: ID
+# an opaque identifier which must be unique in squid.conf
+#
+# vectoring_point: reqmod_precache|reqmod_postcache|respmod_precache|respmod_postcache
+# This specifies at which point of transaction processing the
+# ICAP service should be activated. *_postcache vectoring points
+# are not yet supported.
+#
+# service_url: icap://servername:port/servicepath
+# ICAP server and service location.
+#
+# ICAP does not allow a single service to handle both REQMOD and RESPMOD
+# transactions. Squid does not enforce that requirement. You can specify
+# services with the same service_url and different vectoring_points. You
+# can even specify multiple identical services as long as their
+# service_names differ.
+#
+#
+# Service options are separated by white space. ICAP services support
+# the following name=value options:
+#
+# bypass=on|off|1|0
+# If set to 'on' or '1', the ICAP service is treated as
+# optional. If the service cannot be reached or malfunctions,
+# Squid will try to ignore any errors and process the message as
+# if the service was not enabled. No all ICAP errors can be
+# bypassed. If set to 0, the ICAP service is treated as
+# essential and all ICAP errors will result in an error page
+# returned to the HTTP client.
+#
+# Bypass is off by default: services are treated as essential.
+#
+# routing=on|off|1|0
+# If set to 'on' or '1', the ICAP service is allowed to
+# dynamically change the current message adaptation plan by
+# returning a chain of services to be used next. The services
+# are specified using the X-Next-Services ICAP response header
+# value, formatted as a comma-separated list of service names.
+# Each named service should be configured in squid.conf and
+# should have the same method and vectoring point as the current
+# ICAP transaction. Services violating these rules are ignored.
+# An empty X-Next-Services value results in an empty plan which
+# ends the current adaptation.
+#
+# Routing is not allowed by default: the ICAP X-Next-Services
+# response header is ignored.
+#
+# ipv6=on|off
+# Only has effect on split-stack systems. The default on those systems
+# is to use IPv4-only connections. When set to 'on' this option will
+# make Squid use IPv6-only connections to contact this ICAP service.
+#
+# Older icap_service format without optional named parameters is

+# Modern IP resolvers in squid sort lookup results by preferred access.
+# By default squid will use these IP in order and only rotates to
+# the next listed when the most preffered fails.
+#
+# Some load balancing servers based on round robin DNS have been
+# found not to preserve user session state across requests
+# to different IP addresses.
+#
+# Enabling this directive Squid rotates IP's per request.
+#Default:
+# balance_on_multiple_ip off
+
+# TAG: pipeline_prefetch
+# To boost the performance of pipelined requests to closer
+# match that of a non-proxied environment Squid can try to fetch
+# up to two requests in parallel from a pipeline.
+#
+# Defaults to off for bandwidth management and access logging
+# reasons.
+#
+# WARNING: pipelining breaks NTLM and Negotiate/Kerberos authentication.
+#Default:
+# pipeline_prefetch off
+
+# TAG: high_response_time_warning (msec)
+# If the one-minute median response time exceeds this value,
+# Squid prints a WARNING with debug level 0 to get the
+# administrators attention. The value is in milliseconds.
+#Default:
+# high_response_time_warning 0
+
+# TAG: high_page_fault_warning
+# If the one-minute average page fault rate exceeds this
+# value, Squid prints a WARNING with debug level 0 to get
+# the administrators attention. The value is in page faults
+# per second.
+#Default:
+# high_page_fault_warning 0
+
+# TAG: high_memory_warning
+# If the memory usage (as determined by mallinfo) exceeds
+# this amount, Squid prints a WARNING with debug level 0 to get
+# the administrators attention.
+#Default:
+# high_memory_warning 0 KB
+
+# TAG: sleep_after_fork (microseconds)
+# When this is set to a non-zero value, the main Squid process
+# sleeps the specified number of microseconds after a fork()
+# system call. This sleep may help the situation where your
+# system reports fork() failures due to lack of (virtual)
+# memory. Note, however, if you have a lot of child
+# processes, these sleep delays will add up and your
+# Squid will not service requests for some amount of time
+# until all the child processes have been started.
+# On Windows value less then 1000 (1 milliseconds) are
+# rounded to 1000.
+#Default:
+# sleep_after_fork 0
+
+# TAG: windows_ipaddrchangemonitor on|off
+# On Windows Squid by default will monitor IP address changes and will
+# reconfigure itself after any detected event. This is very useful for
+# proxies connected to internet with dial-up interfaces.
+# In some cases (a Proxy server acting as VPN gateway is one) it could be
+# desiderable to disable this behaviour setting this to 'off'.
+# Note: after changing this, Squid service must be restarted.
+#Default:
+# windows_ipaddrchangemonitor on
+
+# TAG: max_filedescriptors
+# The maximum number of filedescriptors supported.
+#
+# The default "0" means Squid inherits the current ulimit setting.
+#
+# Note: Changing this requires a restart of Squid. Also
+# not all comm loops supports large values.
+#Default:
+# max_filedescriptors 0

+# WELCOME TO SQUID 3.1.20
+# ----------------------------
+#
+# This is the documentation for the Squid configuration file.
+# This documentation can also be found online at:
+# http://www.squid-cache.org/Doc/config/
+#
+# You may wish to look at the Squid home page and wiki for the
+# FAQ and other documentation:
+# http://www.squid-cache.org/
+# http://wiki.squid-cache.org/SquidFaq
+# http://wiki.squid-cache.org/ConfigExamples
+#
+# This documentation shows what the defaults for various directives
+# happen to be. If you don't need to change the default, you should
+# leave the line out of your squid.conf in most cases.
+#
+# In some cases "none" refers to no default setting at all,
+# while in other cases it refers to the value of the option
+# - the comments for that keyword indicate if this is the case.
+#
+
+# Configuration options can be included using the "include" directive.
+# Include takes a list of files to include. Quoting and wildcards are
+# supported.
+#
+# For example,
+#
+# include /path/to/included/file/squid.acl.config
+#
+# Includes can be nested up to a hard-coded depth of 16 levels.
+# This arbitrary restriction is to prevent recursive include references
+# from causing Squid entering an infinite loop whilst trying to load
+# configuration files.
+
+# TAG: dns_testnames
+# Remove this line. DNS is no longer tested on startup.
+#Default:
+# none
+
+# TAG: extension_methods
+# Remove this line. All valid methods for HTTP are accepted by default.
+#Default:
+# none
+
+# TAG: incoming_rate
+#Default:
+# none
+
+# TAG: server_http11
+# Remove this line. HTTP/1.1 is supported by default.
+#Default:

+
+# TAG: upgrade_http0.9
+# Remove this line. ICY/1.0 streaming protocol is supported by default.

+# TAG: zph_local
+# Alter these entries. Use the qos_flows directive instead.

+
+# TAG: header_access

+# depending on whether you wish to match client requests or server replies.
+#Default:
+# none
+

+#Default:
+# none
+
+# OPTIONS FOR AUTHENTICATION
+# -----------------------------------------------------------------------------
+
+# TAG: auth_param
+# This is used to define parameters for the various authentication
+# schemes supported by Squid.
+#
+# format: auth_param scheme parameter [setting]
+#
+# The order in which authentication schemes are presented to the client is
+# dependent on the order the scheme first appears in config file. IE
+# has a bug (it's not RFC 2617 compliant) in that it will use the basic
+# scheme if basic is the first entry presented, even if more secure
+# schemes are presented. For now use the order in the recommended
+# settings section below. If other browsers have difficulties (don't
+# recognize the schemes offered even if you are using basic) either
+# put basic first, or disable the other schemes (by commenting out their
+# program entry).
+#
+# Once an authentication scheme is fully configured, it can only be
+# shutdown by shutting squid down and restarting. Changes can be made on
+# the fly and activated with a reconfigure. I.E. You can change to a
+# different helper, but not unconfigure the helper completely.
+#
+# Please note that while this directive defines how Squid processes
+# authentication it does not automatically activate authentication.
+# To use authentication you must in addition make use of ACLs based
+# on login name in http_access (proxy_auth, proxy_auth_regex or
+# external with %LOGIN used in the format tag). The browser will be
+# challenged for authentication on the first such acl encountered
+# in http_access processing and will also be re-challenged for new
+# login credentials if the request is being denied by a proxy_auth
+# type acl.
+#
+# WARNING: authentication can't be used in a transparently intercepting
+# proxy as the client then thinks it is talking to an origin server and
+# not the proxy. This is a limitation of bending the TCP/IP protocol to
+# transparently intercepting port 80, not a limitation in Squid.
+# Ports flagged 'transparent', 'intercept', or 'tproxy' have
+# authentication disabled.
+#
+# === Parameters for the basic scheme follow. ===
+#
+# "program" cmdline
+# Specify the command for the external authenticator. Such a program
+# reads a line containing "username password" and replies "OK" or
+# "ERR" in an endless loop. "ERR" responses may optionally be followed
+# by a error description available as %m in the returned error page.
+# If you use an authenticator, make sure you have 1 acl of type
+# proxy_auth.
+#
+# By default, the basic authentication scheme is not used unless a
+# program is specified.
+#
+# If you want to use the traditional NCSA proxy authentication, set
+# this line to something like
+#
+# auth_param basic program /usr/lib/squid3/ncsa_auth /usr/etc/passwd
+#
+# "utf8" on|off
+# HTTP uses iso-latin-1 as characterset, while some authentication
+# backends such as LDAP expects UTF-8. If this is set to on Squid will
+# translate the HTTP iso-latin-1 charset to UTF-8 before sending the
+# username & password to the helper.
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn. If you start too few
+# Squid will have to wait for them to process a backlog of credential
+# verifications, slowing it down. When password verifications are
+# done via a (slow) network you are likely to need lots of
+# authenticator processes.
+# auth_param basic children 5
+#
+# "concurrency" concurrency
+# The number of concurrent requests the helper can process.
+# The default of 0 is used for helpers who only supports
+# one request at a time. Setting this changes the protocol used to
+# include a channel number first on the request/response line, allowing
+# multiple requests to be sent to the same helper in parallell without
+# wating for the response.
+# Must not be set unless it's known the helper supports this.
+# auth_param basic concurrency 0
+#
+# "realm" realmstring
+# Specifies the realm name which is to be reported to the
+# client for the basic proxy authentication scheme (part of
+# the text the user will see when prompted their username and
+# password). There is no default.
+# auth_param basic realm Squid proxy-caching web server
+#
+# "credentialsttl" timetolive
+# Specifies how long squid assumes an externally validated
+# username:password pair is valid for - in other words how
+# often the helper program is called for that user. Set this
+# low to force revalidation with short lived passwords. Note
+# setting this high does not impact your susceptibility
+# to replay attacks unless you are using an one-time password
+# system (such as SecureID). If you are using such a system,
+# you will be vulnerable to replay attacks unless you also
+# use the max_user_ip ACL in an http_access rule.
+#
+# "casesensitive" on|off
+# Specifies if usernames are case sensitive. Most user databases are
+# case insensitive allowing the same username to be spelled using both
+# lower and upper case letters, but some are case sensitive. This
+# makes a big difference for user_max_ip ACL processing and similar.
+# auth_param basic casesensitive off
+#
+# === Parameters for the digest scheme follow ===
+#
+# "program" cmdline
+# Specify the command for the external authenticator. Such
+# a program reads a line containing "username":"realm" and
+# replies with the appropriate H(A1) value hex encoded or
+# ERR if the user (or his H(A1) hash) does not exists.
+# See rfc 2616 for the definition of H(A1).
+# "ERR" responses may optionally be followed by a error description
+# available as %m in the returned error page.
+#
+# By default, the digest authentication scheme is not used unless a
+# program is specified.
+#
+# If you want to use a digest authenticator, set this line to
+# something like
+#
+# auth_param digest program /usr/lib/squid3/digest_pw_auth /usr/etc/digpass
+#
+# "utf8" on|off
+# HTTP uses iso-latin-1 as characterset, while some authentication
+# backends such as LDAP expects UTF-8. If this is set to on Squid will
+# translate the HTTP iso-latin-1 charset to UTF-8 before sending the
+# username & password to the helper.
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to
+# process a backlog of H(A1) calculations, slowing it down.
+# When the H(A1) calculations are done via a (slow) network
+# you are likely to need lots of authenticator processes.
+# auth_param digest children 5
+#
+# "realm" realmstring
+# Specifies the realm name which is to be reported to the
+# client for the digest proxy authentication scheme (part of
+# the text the user will see when prompted their username and
+# password). There is no default.
+# auth_param digest realm Squid proxy-caching web server
+#
+# "nonce_garbage_interval" timeinterval
+# Specifies the interval that nonces that have been issued
+# to client_agent's are checked for validity.
+#
+# "nonce_max_duration" timeinterval
+# Specifies the maximum length of time a given nonce will be
+# valid for.
+#
+# "nonce_max_count" number
+# Specifies the maximum number of times a given nonce can be
+# used.
+#
+# "nonce_strictness" on|off
+# Determines if squid requires strict increment-by-1 behavior
+# for nonce counts, or just incrementing (off - for use when
+# useragents generate nonce counts that occasionally miss 1
+# (ie, 1,2,4,6)). Default off.
+#
+# "check_nonce_count" on|off
+# This directive if set to off can disable the nonce count check
+# completely to work around buggy digest qop implementations in
+# certain mainstream browser versions. Default on to check the
+# nonce count to protect from authentication replay attacks.
+#
+# "post_workaround" on|off
+# This is a workaround to certain buggy browsers who sends
+# an incorrect request digest in POST requests when reusing
+# the same nonce as acquired earlier on a GET request.
+#
+# === NTLM scheme options follow ===
+#
+# "program" cmdline
+# Specify the command for the external NTLM authenticator.
+# Such a program reads exchanged NTLMSSP packets with
+# the browser via Squid until authentication is completed.
+# If you use an NTLM authenticator, make sure you have 1 acl
+# of type proxy_auth. By default, the NTLM authenticator_program
+# is not used.
+#
+# auth_param ntlm program /usr/lib/squid3/ntlm_auth
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to
+# process a backlog of credential verifications, slowing it
+# down. When credential verifications are done via a (slow)
+# network you are likely to need lots of authenticator
+# processes.
+#
+# auth_param ntlm children 5
+#
+# "keep_alive" on|off
+# Whether to keep the connection open after the initial response where
+# Squid tells the browser which schemes are supported by the proxy.
+# Some browsers are known to present many login popups or to corrupt

+# comma-separated list of the IP addresses in the chain, with the
+# rightmost address being the most recent.
+#
+# If a request reaches us from a source that is allowed by this
+# configuration item, then we consult the X-Forwarded-For header
+# to see where that host received the request from. If the
+# X-Forwarded-For header contains multiple addresses, we continue

+# the address we are testing and srcdomain matches its rDNS.
+#
+# The end result of this process is an IP address that we will

+# TAG: reply_body_max_size size [acl acl...]
+# This option specifies the maximum size of a reply body. It can be
+# used to prevent users from downloading very large files, such as
+# MP3's and movies. When the reply headers are received, the
+# reply_body_max_size lines are processed, and the first line where
+# all (if any) listed ACLs are true is used as the maximum body size
+# for this reply.
+#
+# This size is checked twice. First when we get the reply headers,
+# we check the content-length value. If the content length value exists
+# and is larger than the allowed size, the request is denied and the
+# user receives an error message that says "the request or reply
+# is too large." If there is no content-length, and the reply
+# size exceeds this limit, the client's connection is just closed
+# and they will receive a partial reply.
+#
+# WARNING: downstream caches probably can not detect a partial reply
+# if there is no content-length header, so they will cache
+# partial responses and give them out as hits. You should NOT
+# use this option if you have downstream caches.
+#
+# WARNING: A maximum size smaller than the size of squid's error messages
+# will cause an infinite loop and crash squid. Ensure that the smallest

+# The defaults will prevent peer traffic using HTCP.
+#
+#
+# htcp Send HTCP, instead of ICP, queries to the neighbor.
+# You probably also want to set the "icp-port" to 4827
+# instead of 3130.
+#
+# htcp-oldsquid Send HTCP to old Squid versions.
+#
+# htcp-no-clr Send HTCP to the neighbor but without
+# sending any CLR requests. This cannot be used with
+# htcp-only-clr.
+#
+# htcp-only-clr Send HTCP to the neighbor but ONLY CLR requests.
+# This cannot be used with htcp-no-clr.
+#
+# htcp-no-purge-clr
+# Send HTCP to the neighbor including CLRs but only when
+# they do not result from PURGE requests.
+#
+# htcp-forward-clr
+# Forward any HTCP CLR requests this proxy receives to the peer.
+#
+#
+# ==== PEER SELECTION METHODS ====
+#
+# The default peer selection method is ICP, with the first responding peer
+# being used as source. These options can be used for better load balancing.
+#
+#
+# default This is a parent cache which can be used as a "last-resort"
+# if a peer cannot be located by any of the peer-selection methods.
+# If specified more than once, only the first is used.
+#
+# round-robin Load-Balance parents which should be used in a round-robin
+# fashion in the absence of any ICP queries.
+# weight=N can be used to add bias.
+#
+# weighted-round-robin
+# Load-Balance parents which should be used in a round-robin
+# fashion with the frequency of each parent being based on the
+# round trip time. Closer parents are used more often.
+# Usually used for background-ping parents.
+# weight=N can be used to add bias.
+#
+# carp Load-Balance parents which should be used as a CARP array.
+# The requests will be distributed among the parents based on the
+# CARP load balancing hash function based on their weight.
+#
+# userhash Load-balance parents based on the client proxy_auth or ident username.
+#
+# sourcehash Load-balance parents based on the client source IP.
+#
+# multicast-siblings
+# To be used only for cache peers of type "multicast".
+# ALL members of this multicast group have "sibling"
+# relationship with it, not "parent". This is to a multicast
+# group when the requested object would be fetched only from
+# a "parent" cache, anyway. It's useful, e.g., when
+# configuring a pool of redundant Squid proxies, being
+# members of the same multicast group.
+#
+#
+# ==== PEER SELECTION OPTIONS ====
+#
+# weight=N use to affect the selection of a peer during any weighted
+# peer-selection mechanisms.
+# The weight must be an integer; default is 1,
+# larger weights are favored more.
+# This option does not affect parent selection if a peering
+# protocol is not in use.
+#
+# basetime=N Specify a base amount to be subtracted from round trip
+# times of parents.
+# It is subtracted before division by weight in calculating
+# which parent to fectch from. If the rtt is less than the
+# base time the rtt is set to a minimal value.
+#
+# ttl=N Specify a TTL to use when sending multicast ICP queries
+# to this address.
+# Only useful when sending to a multicast group.
+# Because we don't accept ICP replies from random
+# hosts, you must configure other group members as
+# peers with the 'multicast-responder' option.
+#
+# no-delay To prevent access to this neighbor from influencing the
+# delay pools.
+#
+# digest-url=URL Tell Squid to fetch the cache digest (if digests are
+# enabled) for this host from the specified URL rather
+# than the Squid default location.
+#
+#
+# ==== ACCELERATOR / REVERSE-PROXY OPTIONS ====
+#
+# originserver Causes this parent to be contacted as an origin server.
+# Meant to be used in accelerator setups when the peer
+# is a web server.
+#
+# forceddomain=name
+# Set the Host header of requests forwarded to this peer.
+# Useful in accelerator setups where the server (peer)
+# expects a certain domain name but clients may request
+# others. ie example.com or www.example.com
+#
+# no-digest Disable request of cache digests.
+#
+# no-netdb-exchange
+# Disables requesting ICMP RTT database (NetDB).
+#
+#
+# ==== AUTHENTICATION OPTIONS ====
+#
+# login=user:password
+# If this is a personal/workgroup proxy and your parent
+# requires proxy authentication.
+#
+# Note: The string can include URL escapes (i.e. %20 for
+# spaces). This also means % must be written as %%.
+#
+# login=PROXYPASS
+# Send login details received from client to this peer.
+# Authentication is not required, nor changed.
+#
+# Note: This will pass any form of authentication but
+# only Basic auth will work through a proxy unless the
+# connection-auth options are also used.
+#
+# login=PASS Send login details received from client to this peer.
+# Authentication is not required by this option.
+# If there are no client-provided authentication headers
+# to pass on, but username and password are available
+# from either proxy login or an external ACL user= and
+# password= result tags they may be sent instead.
+#
+# Note: To combine this with proxy_auth both proxies must
+# share the same user database as HTTP only allows for
+# a single login (one for proxy, one for origin server).
+# Also be warned this will expose your users proxy
+# password to the peer. USE WITH CAUTION
+#
+# login=*:password
+# Send the username to the upstream cache, but with a
+# fixed password. This is meant to be used when the peer
+# is in another administrative domain, but it is still
+# needed to identify each user.
+# The star can optionally be followed by some extra
+# information which is added to the username. This can
+# be used to identify this proxy to the peer, similar to
+# the login=username:password option above.
+#
+# connection-auth=on|off
+# Tell Squid that this peer does or not support Microsoft
+# connection oriented authentication, and any such
+# challenges received from there should be ignored.
+# Default is auto to automatically determine the status
+# of the peer.
+#
+#
+# ==== SSL / HTTPS / TLS OPTIONS ====
+#
+# ssl Encrypt connections to this peer with SSL/TLS.
+#
+# sslcert=/path/to/ssl/certificate
+# A client SSL certificate to use when connecting to
+# this peer.
+#
+# sslkey=/path/to/ssl/key
+# The private SSL key corresponding to sslcert above.
+# If 'sslkey' is not specified 'sslcert' is assumed to
+# reference a combined file containing both the
+# certificate and the key.
+#
+# sslversion=1|2|3|4
+# The SSL version to use when connecting to this peer
+# 1 = automatic (default)
+# 2 = SSL v2 only
+# 3 = SSL v3 only
+# 4 = TLS v1 only
+#
+# sslcipher=... The list of valid SSL ciphers to use when connecting
+# to this peer.
+#
+# ssloptions=... Specify various SSL engine options:
+# NO_SSLv2 Disallow the use of SSLv2
+# NO_SSLv3 Disallow the use of SSLv3
+# NO_TLSv1 Disallow the use of TLSv1
+# See src/ssl_support.c or the OpenSSL documentation for
+# a more complete list.
+#
+# sslcafile=... A file containing additional CA certificates to use
+# when verifying the peer certificate.
+#
+# sslcapath=... A directory containing additional CA certificates to
+# use when verifying the peer certificate.
+#
+# sslcrlfile=... A certificate revocation list file to use when
+# verifying the peer certificate.
+#
+# sslflags=... Specify various flags modifying the SSL implementation:
+#
+# DONT_VERIFY_PEER
+# Accept certificates even if they fail to
+# verify.
+# NO_DEFAULT_CA
+# Don't use the default CA list built in
+# to OpenSSL.
+# DONT_VERIFY_DOMAIN
+# Don't verify the peer certificate
+# matches the server name
+#
+# ssldomain= The peer name as advertised in it's certificate.
+# Used for verifying the correctness of the received peer
+# certificate. If not specified the peer hostname will be
+# used.
+#
+# front-end-https
+# Enable the "Front-End-Https: On" header needed when
+# using Squid as a SSL frontend in front of Microsoft OWA.
+# See MS KB document Q307347 for details on this header.
+# If set to auto the header will only be added if the
+# request is forwarded as a https:// URL.
+#
+#
+# ==== GENERAL OPTIONS ====
+#
+# connect-timeout=N
+# A peer-specific connect timeout.
+# Also see the peer_connect_timeout directive.
+#
+# connect-fail-limit=N
+# How many times connecting to a peer must fail before
+# it is marked as down. Default is 10.
+#
+# allow-miss Disable Squid's use of only-if-cached when forwarding
+# requests to siblings. This is primarily useful when
+# icp_hit_stale is used by the sibling. To extensive use
+# of this option may result in forwarding loops, and you
+# should avoid having two-way peerings with this option.
+# For example to deny peer usage on requests from peer
+# by denying cache_peer_access if the source is a peer.
+#
+# max-conn=N Limit the amount of connections Squid may open to this
+# peer. see also
+#
+# name=xxx Unique name for the peer.
+# Required if you have multiple peers on the same host
+# but different ports.
+# This name can be used in cache_peer_access and similar
+# directives to dentify the peer.
+# Can be used by outgoing access controls through the
+# peername ACL type.
+#
+# no-tproxy Do not use the client-spoof TPROXY support when forwarding
+# requests to this peer. Use normal address selection instead.
+#
+# proxy-only objects fetched from the peer will not be stored locally.
+#
+#Default:
+# none
+
+# TAG: cache_peer_domain
+# Use to limit the domains for which a neighbor cache will be
+# queried. Usage:
+#
+# cache_peer_domain cache-host domain [domain ...]
+# cache_peer_domain cache-host !domain
+#
+# For example, specifying
+#
+# cache_peer_domain parent.foo.net .edu
+#
+# has the effect such that UDP query packets are sent to
+# 'bigserver' only when the requested object exists on a
+# server in the .edu domain. Prefixing the domainname
+# with '!' means the cache will be queried for objects
+# NOT in that domain.
+#
+# NOTE: * Any number of domains may be given for a cache-host,
+# either on the same or separate lines.
+# * When multiple domains are given for a particular
+# cache-host, the first matched domain is applied.
+# * Cache hosts with no domain restrictions are queried
+# for all requests.
+# * There are no defaults.
+# * There is also a 'cache_peer_access' tag in the ACL
+# section.
+#Default:
+# none
+
+# TAG: cache_peer_access
+# Similar to 'cache_peer_domain' but provides more flexibility by
+# using ACL elements.
+#
+# cache_peer_access cache-host allow|deny [!]aclname ...
+#
+# The syntax is identical to 'http_access' and the other lists of
+# ACL elements. See the comments for 'http_access' below, or
+# the Squid FAQ (http://wiki.squid-cache.org/SquidFaq/SquidAcl).
+#Default:
+# none
+
+# TAG: neighbor_type_domain
+# usage: neighbor_type_domain neighbor parent|sibling domain domain ...
+#
+# Modifying the neighbor type for specific domains is now
+# possible. You can treat some domains differently than the the
+# default neighbor type specified on the 'cache_peer' line.
+# Normally it should only be necessary to list domains which
+# should be treated differently because the default neighbor type
+# applies for hostnames which do not match domains listed here.
+#
+#EXAMPLE:
+# cache_peer cache.foo.org parent 3128 3130
+# neighbor_type_domain cache.foo.org sibling .com .net
+# neighbor_type_domain cache.foo.org sibling .au .de
+#Default:
+# none
+
+# TAG: dead_peer_timeout (seconds)
+# This controls how long Squid waits to declare a peer cache
+# as "dead." If there are no ICP replies received in this
+# amount of time, Squid will declare the peer dead and not
+# expect to receive any further ICP replies. However, it
+# continues to send ICP queries, and will mark the peer as
+# alive upon receipt of the first subsequent ICP reply.
+#
+# This timeout also affects when Squid expects to receive ICP
+# replies from peers. If more than 'dead_peer' seconds have
+# passed since the last ICP reply was received, Squid will not
+# expect to receive an ICP reply on the next query. Thus, if
+# your time between requests is greater than this timeout, you
+# will see a lot of requests sent DIRECT to origin servers
+# instead of to your parents.
+#Default:
+# dead_peer_timeout 10 seconds
+
+# TAG: forward_max_tries
+# Controls how many different forward paths Squid will try
+# before giving up. See also forward_timeout.
+#Default:
+# forward_max_tries 10
+
+# TAG: hierarchy_stoplist
+# A list of words which, if found in a URL, cause the object to
+# be handled directly by this cache. In other words, use this
+# to not query neighbor caches for certain objects. You may
+# list this option multiple times.
+#
+# Example:
+# hierarchy_stoplist cgi-bin ?
+#
+# Note: never_direct overrides this option.
+#Default:
+# none
+
+# MEMORY CACHE OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: cache_mem (bytes)
+# NOTE: THIS PARAMETER DOES NOT SPECIFY THE MAXIMUM PROCESS SIZE.
+# IT ONLY PLACES A LIMIT ON HOW MUCH ADDITIONAL MEMORY SQUID WILL
+# USE AS A MEMORY CACHE OF OBJECTS. SQUID USES MEMORY FOR OTHER
+# THINGS AS WELL. SEE THE SQUID FAQ SECTION 8 FOR DETAILS.
+#
+# 'cache_mem' specifies the ideal amount of memory to be used
+# for:
+# * In-Transit objects
+# * Hot Objects
+# * Negative-Cached objects
+#
+# Data for these objects are stored in 4 KB blocks. This
+# parameter specifies the ideal upper limit on the total size of
+# 4 KB blocks allocated. In-Transit objects take the highest
+# priority.
+#
+# In-transit objects have priority over the others. When
+# additional space is needed for incoming data, negative-cached
+# and hot objects will be released. In other words, the
+# negative-cached and hot objects will fill up any unused space
+# not needed for in-transit objects.
+#
+# If circumstances require, this limit will be exceeded.
+# Specifically, if your incoming request rate requires more than
+# 'cache_mem' of memory to hold in-transit objects, Squid will
+# exceed this limit to satisfy the new requests. When the load
+# decreases, blocks will be freed until the high-water mark is
+# reached. Thereafter, blocks will be used to store hot
+# objects.
+#Default:
+# cache_mem 256 MB
+
+# TAG: maximum_object_size_in_memory (bytes)
+# Objects greater than this size will not be attempted to kept in
+# the memory cache. This should be set high enough to keep objects
+# accessed frequently in memory to improve performance whilst low
+# enough to keep larger objects from hoarding cache_mem.
+#Default:
+# maximum_object_size_in_memory 512 KB
+
+# TAG: memory_replacement_policy
+# The memory replacement policy parameter determines which
+# objects are purged from memory when memory space is needed.
+#
+# See cache_replacement_policy for details.
+#Default:
+# memory_replacement_policy lru
+
+# DISK CACHE OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: cache_replacement_policy
+# The cache replacement policy parameter determines which
+# objects are evicted (replaced) when disk space is needed.
+#
+# lru : Squid's original list based LRU policy
+# heap GDSF : Greedy-Dual Size Frequency
+# heap LFUDA: Least Frequently Used with Dynamic Aging
+# heap LRU : LRU policy implemented using a heap
+#
+# Applies to any cache_dir lines listed below this.
+#
+# The LRU policies keeps recently referenced objects.
+#
+# The heap GDSF policy optimizes object hit rate by keeping smaller
+# popular objects in cache so it has a better chance of getting a
+# hit. It achieves a lower byte hit rate than LFUDA though since
+# it evicts larger (possibly popular) objects.
+#
+# The heap LFUDA policy keeps popular objects in cache regardless of
+# their size and thus optimizes byte hit rate at the expense of
+# hit rate since one large, popular object will prevent many
+# smaller, slightly less popular objects from being cached.
+#
+# Both policies utilize a dynamic aging mechanism that prevents
+# cache pollution that can otherwise occur with frequency-based
+# replacement policies.
+#
+# NOTE: if using the LFUDA replacement policy you should increase
+# the value of maximum_object_size above its default of 4096 KB to
+# to maximize the potential byte hit rate improvement of LFUDA.
+#
+# For more information about the GDSF and LFUDA cache replacement

+# TAG: cache_dir
+# Usage:
+#
+# cache_dir Type Directory-Name Fs-specific-data [options]
+#
+# You can specify multiple cache_dir lines to spread the
+# cache among different disk partitions.
+#
+# Type specifies the kind of storage system to use. Only "ufs"
+# is built by default. To enable any of the other storage systems
+# see the --enable-storeio configure option.
+#
+# 'Directory' is a top-level directory where cache swap
+# files will be stored. If you want to use an entire disk
+# for caching, this can be the mount-point directory.
+# The directory must exist and be writable by the Squid
+# process. Squid will NOT create this directory for you.
+#
+# The ufs store type:
+#
+# "ufs" is the old well-known Squid storage format that has always
+# been there.
+#
+# cache_dir ufs Directory-Name Mbytes L1 L2 [options]
+#
+# 'Mbytes' is the amount of disk space (MB) to use under this
+# directory. The default is 100 MB. Change this to suit your
+# configuration. Do NOT put the size of your disk drive here.
+# Instead, if you want Squid to use the entire disk drive,
+# subtract 20% and use that value.
+#
+# 'L1' is the number of first-level subdirectories which
+# will be created under the 'Directory'. The default is 16.
+#
+# 'L2' is the number of second-level subdirectories which
+# will be created under each first-level directory. The default
+# is 256.
+#
+# The aufs store type:
+#
+# "aufs" uses the same storage format as "ufs", utilizing
+# POSIX-threads to avoid blocking the main Squid process on
+# disk-I/O. This was formerly known in Squid as async-io.
+#
+# cache_dir aufs Directory-Name Mbytes L1 L2 [options]
+#
+# see argument descriptions under ufs above

+# separate process to avoid blocking the main Squid process on
+# disk-I/O.
+#
+# cache_dir diskd Directory-Name Mbytes L1 L2 [options] [Q1=n] [Q2=n]
+#
+# see argument descriptions under ufs above
+#
+# Q1 specifies the number of unacknowledged I/O requests when Squid
+# stops opening new files. If this many messages are in the queues,
+# Squid won't open new files. Default is 64
+#
+# Q2 specifies the number of unacknowledged messages when Squid
+# starts blocking. If this many messages are in the queues,
+# Squid blocks until it receives some replies. Default is 72
+#
+# When Q1 < Q2 (the default), the cache directory is optimized
+# for lower response time at the expense of a decrease in hit
+# ratio. If Q1 > Q2, the cache directory is optimized for
+# higher hit ratio at the expense of an increase in response
+# time.
+#
+# The coss store type:
+#
+# NP: COSS filesystem in Squid-3 has been deemed too unstable for
+# production use and has thus been removed from this release.
+# We hope that it can be made usable again soon.
+#
+# block-size=n defines the "block size" for COSS cache_dir's.
+# Squid uses file numbers as block numbers. Since file numbers
+# are limited to 24 bits, the block size determines the maximum
+# size of the COSS partition. The default is 512 bytes, which
+# leads to a maximum cache_dir size of 512<<24, or 8 GB. Note
+# you should not change the coss block size after Squid
+# has written some objects to the cache_dir.
+#
+# The coss file store has changed from 2.5. Now it uses a file
+# called 'stripe' in the directory names in the config - and
+# this will be created by squid -z.
+#
+# Common options:
+#
+# no-store, no new objects should be stored to this cache_dir
+#
+# max-size=n, refers to the max object size in bytes this cache_dir
+# supports. It is used to select the cache_dir to store the object.
+# Note: To make optimal use of the max-size limits you should order
+# the cache_dir lines with the smallest max-size value first and the
+# ones with no max-size specification last.
+#
+# Note for coss, max-size must be less than COSS_MEMBUF_SZ,
+# which can be changed with the --with-coss-membuf-size=N configure
+# option.

+#
+# If adaptation is enabled the following two codes become available:
+#
+# adapt::sum_trs Summed adaptation transaction response

+# adapt::all_trs.
+#
+# adapt::all_trs All adaptation transaction response times.
+# Same as adaptation_strs but response times of
+# individual transactions are never added

+# times are recorded individually.
+#
+# You can prefix adapt::*_trs format codes with adaptation

+# For REQMOD, there is no HTTP response header unless the ICAP
+# server performed request satisfaction. For RESPMOD, the HTTP
+# request header is the header sent to the ICAP server. For
+# OPTIONS, there are no HTTP headers.
+#
+# The following format codes are also available for ICAP logs:
+#
+# icap::<A ICAP server IP address. Similar to <A.
+#
+# icap::<service_name ICAP service name from the icap_service
+# option in Squid configuration file.
+#
+# icap::ru ICAP Request-URI. Similar to ru.

+# stops when the transaction is completed.
+# Similar to tr.
+#
+# icap::tio Transaction I/O time (in milliseconds). The
+# timer starts when the first ICAP request
+# byte is scheduled for sending. The timers

+# TAG: cache_swap_state
+# Location for the cache "swap.state" file. This index file holds

+
+# OPTIONS FOR THE CACHE REGISTRATION SERVICE
+# -----------------------------------------------------------------------------
+#
+# This section contains parameters for the (optional) cache
+# announcement service. This service is provided to help
+# cache administrators locate one another in order to join or
+# create cache hierarchies.
+#
+# An 'announcement' message is sent (via UDP) to the registration
+# service by Squid. By default, the announcement message is NOT
+# SENT unless you enable it with 'announce_period' below.
+#
+# The announcement message includes your hostname, plus the
+# following information from this configuration file:
+#
+# http_port
+# icp_port
+# cache_mgr
+#
+# All current information is processed regularly and made
+# available on the Web at http://www.ircache.net/Cache/Tracker/.
+
+# TAG: announce_period
+# This is how frequently to send cache announcements. The
+# default is `0' which disables sending the announcement
+# messages.
+#
+# To enable announcing your cache, just set an announce period.
+#
+# Example:
+# announce_period 1 day
+#Default:
+# announce_period 0
+
+# TAG: announce_host
+#Default:
+# announce_host tracker.ircache.net
+
+# TAG: announce_file
+#Default:
+# none
+
+# TAG: announce_port
+# announce_host and announce_port set the hostname and port
+# number where the registration message will be sent.
+#
+# Hostname will default to 'tracker.ircache.net' and port will
+# default default to 3131. If the 'filename' argument is given,
+# the contents of that file will be included in the announce
+# message.
+#Default:
+# announce_port 3131
+
+# HTTPD-ACCELERATOR OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: httpd_accel_surrogate_id
+# Surrogates (http://www.esi.org/architecture_spec_1.0.html)
+# need an identification token to allow control targeting. Because
+# a farm of surrogates may all perform the same tasks, they may share
+# an identification token.
+#Default:
+# httpd_accel_surrogate_id unset-id
+
+# TAG: http_accel_surrogate_remote on|off
+# Remote surrogates (such as those in a CDN) honour Surrogate-Control: no-store-remote.
+# Set this to on to have squid behave as a remote surrogate.
+#Default:
+# http_accel_surrogate_remote off
+
+# TAG: esi_parser libxml2|expat|custom
+# ESI markup is not strictly XML compatible. The custom ESI parser
+# will give higher performance, but cannot handle non ASCII character
+# encodings.
+#Default:
+# esi_parser custom
+
+# DELAY POOL PARAMETERS
+# -----------------------------------------------------------------------------
+
+# TAG: delay_pools
+# This represents the number of delay pools to be used. For example,
+# if you have one class 2 delay pool and one class 3 delays pool, you
+# have a total of 2 delay pools.
+#Default:
+# delay_pools 0
+
+# TAG: delay_class
+# This defines the class of each delay pool. There must be exactly one
+# delay_class line for each delay pool. For example, to define two
+# delay pools, one of class 2 and one of class 3, the settings above
+# and here would be:
+#
+# Example:
+# delay_pools 4 # 4 delay pools
+# delay_class 1 2 # pool 1 is a class 2 pool
+# delay_class 2 3 # pool 2 is a class 3 pool
+# delay_class 3 4 # pool 3 is a class 4 pool
+# delay_class 4 5 # pool 4 is a class 5 pool
+#
+# The delay pool classes are:
+#
+# class 1 Everything is limited by a single aggregate
+# bucket.
+#
+# class 2 Everything is limited by a single aggregate
+# bucket as well as an "individual" bucket chosen
+# from bits 25 through 32 of the IPv4 address.
+#
+# class 3 Everything is limited by a single aggregate
+# bucket as well as a "network" bucket chosen
+# from bits 17 through 24 of the IP address and a
+# "individual" bucket chosen from bits 17 through
+# 32 of the IPv4 address.
+#
+# class 4 Everything in a class 3 delay pool, with an
+# additional limit on a per user basis. This
+# only takes effect if the username is established
+# in advance - by forcing authentication in your
+# http_access rules.
+#
+# class 5 Requests are grouped according their tag (see
+# external_acl's tag= reply).
+#
+#
+# Each pool also requires a delay_parameters directive to configure the pool size
+# and speed limits used whenever the pool is applied to a request. Along with
+# a set of delay_access directives to determine when it is used.
+#
+# NOTE: If an IP address is a.b.c.d
+# -> bits 25 through 32 are "d"
+# -> bits 17 through 24 are "c"
+# -> bits 17 through 32 are "c * 256 + d"
+#
+# NOTE-2: Due to the use of bitmasks in class 2,3,4 pools they only apply to
+# IPv4 traffic. Class 1 and 5 pools may be used with IPv6 traffic.
+#Default:
+# none
+
+# TAG: delay_access
+# This is used to determine which delay pool a request falls into.
+#
+# delay_access is sorted per pool and the matching starts with pool 1,
+# then pool 2, ..., and finally pool N. The first delay pool where the
+# request is allowed is selected for the request. If it does not allow
+# the request to any pool then the request is not delayed (default).
+#
+# For example, if you want some_big_clients in delay
+# pool 1 and lotsa_little_clients in delay pool 2:
+#
+#Example:
+# delay_access 1 allow some_big_clients
+# delay_access 1 deny all
+# delay_access 2 allow lotsa_little_clients
+# delay_access 2 deny all
+# delay_access 3 allow authenticated_clients
+#Default:
+# none
+
+# TAG: delay_parameters
+# This defines the parameters for a delay pool. Each delay pool has
+# a number of "buckets" associated with it, as explained in the
+# description of delay_class.
+#
+# For a class 1 delay pool, the syntax is:
+# delay_pools pool 1
+# delay_parameters pool aggregate
+#
+# For a class 2 delay pool:
+# delay_pools pool 2
+# delay_parameters pool aggregate individual
+#
+# For a class 3 delay pool:
+# delay_pools pool 3
+# delay_parameters pool aggregate network individual
+#
+# For a class 4 delay pool:
+# delay_pools pool 4
+# delay_parameters pool aggregate network individual user
+#
+# For a class 5 delay pool:
+# delay_pools pool 5
+# delay_parameters pool tagrate
+#
+# The option variables are:
+#
+# pool a pool number - ie, a number between 1 and the
+# number specified in delay_pools as used in
+# delay_class lines.
+#
+# aggregate the speed limit parameters for the aggregate bucket
+# (class 1, 2, 3).
+#
+# individual the speed limit parameters for the individual
+# buckets (class 2, 3).
+#
+# network the speed limit parameters for the network buckets
+# (class 3).
+#
+# user the speed limit parameters for the user buckets
+# (class 4).
+#
+# tagrate the speed limit parameters for the tag buckets
+# (class 5).
+#
+# A pair of delay parameters is written restore/maximum, where restore is
+# the number of bytes (not bits - modem and network speeds are usually
+# quoted in bits) per second placed into the bucket, and maximum is the
+# maximum number of bytes which can be in the bucket at any time.
+#
+# There must be one delay_parameters line for each delay pool.
+#
+#
+# For example, if delay pool number 1 is a class 2 delay pool as in the
+# above example, and is being used to strictly limit each host to 64Kbit/sec
+# (plus overheads), with no overall limit, the line is:
+#
+# delay_parameters 1 -1/-1 8000/8000
+#
+# Note that 8 x 8000 KByte/sec -> 64Kbit/sec.
+#
+# Note that the figure -1 is used to represent "unlimited".
+#
+#
+# And, if delay pool number 2 is a class 3 delay pool as in the above
+# example, and you want to limit it to a total of 256Kbit/sec (strict limit)
+# with each 8-bit network permitted 64Kbit/sec (strict limit) and each
+# individual host permitted 4800bit/sec with a bucket maximum size of 64Kbits
+# to permit a decent web page to be downloaded at a decent speed
+# (if the network is not being limited due to overuse) but slow down
+# large downloads more significantly:
+#
+# delay_parameters 2 32000/32000 8000/8000 600/8000
+#
+# Note that 8 x 32000 KByte/sec -> 256Kbit/sec.
+# 8 x 8000 KByte/sec -> 64Kbit/sec.
+# 8 x 600 Byte/sec -> 4800bit/sec.
+#
+#
+# Finally, for a class 4 delay pool as in the example - each user will
+# be limited to 128Kbits/sec no matter how many workstations they are logged into.:
+#
+# delay_parameters 4 32000/32000 8000/8000 600/64000 16000/16000
+#Default:
+# none
+
+# TAG: delay_initial_bucket_level (percent, 0-100)
+# The initial bucket percentage is used to determine how much is put
+# in each bucket when squid starts, is reconfigured, or first notices
+# a host accessing it (in class 2 and class 3, individual hosts and
+# networks only have buckets associated with them once they have been
+# "seen" by squid).
+#Default:

+
+# TAG: wccp2_service
+# WCCP2 allows for multiple traffic services. There are two

+# -----------------------------------------------------------------------------
+
+# TAG: nonhierarchical_direct
+# By default, Squid will send any non-hierarchical requests
+# (matching hierarchy_stoplist or not cacheable request type) direct
+# to origin servers.
+#
+# If you set this to off, Squid will prefer to send these
+# requests to parents.
+#
+# Note that in most configurations, by turning this off you will only
+# add latency to these request without any improvement in global hit
+# ratio.
+#
+# If you are inside an firewall see never_direct instead of
+# this directive.
+#Default:
+# nonhierarchical_direct on
+
+# TAG: prefer_direct
+# Normally Squid tries to use parents for most requests. If you for some
+# reason like it to first try going direct and only use a parent if
+# going direct fails set this to on.
+#
+# By combining nonhierarchical_direct off and prefer_direct on you
+# can set up Squid to use a parent as a backup path if going direct
+# fails.
+#
+# Note: If you want Squid to use parents for all requests see
+# the never_direct directive. prefer_direct only modifies how Squid
+# acts on cacheable requests.
+#Default:
+# prefer_direct off
+
+# TAG: always_direct
+# Usage: always_direct allow|deny [!]aclname ...
+#
+# Here you can use ACL elements to specify requests which should
+# ALWAYS be forwarded by Squid to the origin servers without using
+# any peers. For example, to always directly forward requests for
+# local servers ignoring any parents or siblings you may have use
+# something like:
+#
+# acl local-servers dstdomain my.domain.net
+# always_direct allow local-servers
+#
+# To always forward FTP requests directly, use
+#
+# acl FTP proto FTP
+# always_direct allow FTP
+#
+# NOTE: There is a similar, but opposite option named
+# 'never_direct'. You need to be aware that "always_direct deny
+# foo" is NOT the same thing as "never_direct allow foo". You
+# may need to use a deny rule to exclude a more-specific case of
+# some other rule. Example:
+#
+# acl local-external dstdomain external.foo.net
+# acl local-servers dstdomain .foo.net
+# always_direct deny local-external
+# always_direct allow local-servers
+#
+# NOTE: If your goal is to make the client forward the request
+# directly to the origin server bypassing Squid then this needs
+# to be done in the client configuration. Squid configuration
+# can only tell Squid how Squid should fetch the object.
+#
+# NOTE: This directive is not related to caching. The replies
+# is cached as usual even if you use always_direct. To not cache
+# the replies see the 'cache' directive.
+#
+# This clause supports both fast and slow acl types.
+# See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
+#Default:
+# none
+
+# TAG: never_direct
+# Usage: never_direct allow|deny [!]aclname ...
+#
+# never_direct is the opposite of always_direct. Please read
+# the description for always_direct if you have not already.
+#
+# With 'never_direct' you can use ACL elements to specify
+# requests which should NEVER be forwarded directly to origin
+# servers. For example, to force the use of a proxy for all
+# requests, except those in your local domain use something like:
+#
+# acl local-servers dstdomain .foo.net
+# never_direct deny local-servers
+# never_direct allow all
+#
+# or if Squid is inside a firewall and there are local intranet
+# servers inside the firewall use something like:
+#
+# acl local-intranet dstdomain .foo.net
+# acl local-external dstdomain external.foo.net
+# always_direct deny local-external
+# always_direct allow local-intranet
+# never_direct allow all

+#Default:
+# dns_timeout 2 minutes
+
+# TAG: dns_defnames on|off
+# Normally the RES_DEFNAMES resolver option is disabled

+# objects that otherwise would be free()d. Thus, it is safe to set
+# memory_pools_limit to a reasonably high value even if your
+# configuration will use less memory.
+#
+# If set to none, Squid will keep all memory it can. That is, there
+# will be no limit on the total amount of memory used for safe-keeping.
+#
+# To disable memory allocation optimization, do not set

+#
+# An overhead for maintaining memory pools is not taken into account

+
+# TAG: retry_on_error
+# If set to ON Squid will automatically retry requests when
+# receiving an error response with status 403 (Forbidden),
+# 500 (Internal Error), 501 or 503 (Service not available).
+# Status 502 and 504 (Gateway errors) are always retried.

+# allow: The request is allowed and the URI is not changed. The
+# whitespace characters remain in the URI. Note the
+# whitespace is passed to redirector processes if they
+# are in use.
+# encode: The request is allowed and the whitespace characters are
+# encoded according to RFC1738. This could be considered
+# a violation of the HTTP/1.1
+# RFC because proxies are not allowed to rewrite URI's.
+# chop: The request is allowed and the URI is chopped at the
+# first whitespace. This might also be considered a
+# violation.
+#Default:
+# uri_whitespace strip
+
+# TAG: chroot
+# Specifies a directory where Squid should do a chroot() while
+# initializing. This also causes Squid to fully drop root
+# privileges after initializing. This means, for example, if you
+# use a HTTP port less than 1024 and try to reconfigure, you may
+# get an error saying that Squid can not open the port.
+#Default:
+# none
+
+# TAG: balance_on_multiple_ip
+# Modern IP resolvers in squid sort lookup results by preferred access.
+# By default squid will use these IP in order and only rotates to

+#
+# Some load balancing servers based on round robin DNS have been

+#
+# Enabling this directive Squid rotates IP's per request.
+#Default:

+
+# TAG: max_filedescriptors
+# The maximum number of filedescriptors supported.

+# WELCOME TO SQUID 3.1.20
+# ----------------------------
+#
+# This is the documentation for the Squid configuration file.
+# This documentation can also be found online at:
+# http://www.squid-cache.org/Doc/config/
+#
+# You may wish to look at the Squid home page and wiki for the
+# FAQ and other documentation:
+# http://www.squid-cache.org/
+# http://wiki.squid-cache.org/SquidFaq
+# http://wiki.squid-cache.org/ConfigExamples
+#
+# This documentation shows what the defaults for various directives
+# happen to be. If you don't need to change the default, you should
+# leave the line out of your squid.conf in most cases.
+#
+# In some cases "none" refers to no default setting at all,
+# while in other cases it refers to the value of the option
+# - the comments for that keyword indicate if this is the case.
+#
+
+# Configuration options can be included using the "include" directive.
+# Include takes a list of files to include. Quoting and wildcards are
+# supported.
+#
+# For example,
+#
+# include /path/to/included/file/squid.acl.config
+#
+# Includes can be nested up to a hard-coded depth of 16 levels.
+# This arbitrary restriction is to prevent recursive include references
+# from causing Squid entering an infinite loop whilst trying to load
+# configuration files.
+
+# TAG: dns_testnames
+# Remove this line. DNS is no longer tested on startup.
+#Default:
+# none
+
+# TAG: extension_methods
+# Remove this line. All valid methods for HTTP are accepted by default.
+#Default:
+# none
+
+# TAG: incoming_rate

+
+# TAG: server_http11
+# Remove this line. HTTP/1.1 is supported by default.

+
+# OPTIONS FOR AUTHENTICATION
+# -----------------------------------------------------------------------------
+
+# TAG: auth_param
+# This is used to define parameters for the various authentication
+# schemes supported by Squid.
+#
+# format: auth_param scheme parameter [setting]
+#
+# The order in which authentication schemes are presented to the client is
+# dependent on the order the scheme first appears in config file. IE
+# has a bug (it's not RFC 2617 compliant) in that it will use the basic
+# scheme if basic is the first entry presented, even if more secure
+# schemes are presented. For now use the order in the recommended
+# settings section below. If other browsers have difficulties (don't
+# recognize the schemes offered even if you are using basic) either
+# put basic first, or disable the other schemes (by commenting out their
+# program entry).
+#
+# Once an authentication scheme is fully configured, it can only be
+# shutdown by shutting squid down and restarting. Changes can be made on
+# the fly and activated with a reconfigure. I.E. You can change to a
+# different helper, but not unconfigure the helper completely.
+#
+# Please note that while this directive defines how Squid processes
+# authentication it does not automatically activate authentication.
+# To use authentication you must in addition make use of ACLs based
+# on login name in http_access (proxy_auth, proxy_auth_regex or
+# external with %LOGIN used in the format tag). The browser will be
+# challenged for authentication on the first such acl encountered
+# in http_access processing and will also be re-challenged for new
+# login credentials if the request is being denied by a proxy_auth
+# type acl.
+#
+# WARNING: authentication can't be used in a transparently intercepting
+# proxy as the client then thinks it is talking to an origin server and
+# not the proxy. This is a limitation of bending the TCP/IP protocol to
+# transparently intercepting port 80, not a limitation in Squid.
+# Ports flagged 'transparent', 'intercept', or 'tproxy' have
+# authentication disabled.
+#
+# === Parameters for the basic scheme follow. ===
+#
+# "program" cmdline
+# Specify the command for the external authenticator. Such a program
+# reads a line containing "username password" and replies "OK" or
+# "ERR" in an endless loop. "ERR" responses may optionally be followed
+# by a error description available as %m in the returned error page.
+# If you use an authenticator, make sure you have 1 acl of type
+# proxy_auth.
+#
+# By default, the basic authentication scheme is not used unless a
+# program is specified.
+#
+# If you want to use the traditional NCSA proxy authentication, set
+# this line to something like
+#
+# auth_param basic program /usr/lib/squid3/ncsa_auth /usr/etc/passwd
+#
+# "utf8" on|off
+# HTTP uses iso-latin-1 as characterset, while some authentication
+# backends such as LDAP expects UTF-8. If this is set to on Squid will
+# translate the HTTP iso-latin-1 charset to UTF-8 before sending the
+# username & password to the helper.
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn. If you start too few
+# Squid will have to wait for them to process a backlog of credential
+# verifications, slowing it down. When password verifications are
+# done via a (slow) network you are likely to need lots of
+# authenticator processes.
+# auth_param basic children 5
+#
+# "concurrency" concurrency
+# The number of concurrent requests the helper can process.
+# The default of 0 is used for helpers who only supports
+# one request at a time. Setting this changes the protocol used to
+# include a channel number first on the request/response line, allowing
+# multiple requests to be sent to the same helper in parallell without
+# wating for the response.
+# Must not be set unless it's known the helper supports this.
+# auth_param basic concurrency 0
+#
+# "realm" realmstring
+# Specifies the realm name which is to be reported to the
+# client for the basic proxy authentication scheme (part of
+# the text the user will see when prompted their username and
+# password). There is no default.
+# auth_param basic realm Squid proxy-caching web server
+#
+# "credentialsttl" timetolive
+# Specifies how long squid assumes an externally validated
+# username:password pair is valid for - in other words how
+# often the helper program is called for that user. Set this
+# low to force revalidation with short lived passwords. Note
+# setting this high does not impact your susceptibility
+# to replay attacks unless you are using an one-time password
+# system (such as SecureID). If you are using such a system,
+# you will be vulnerable to replay attacks unless you also
+# use the max_user_ip ACL in an http_access rule.
+#
+# "casesensitive" on|off
+# Specifies if usernames are case sensitive. Most user databases are
+# case insensitive allowing the same username to be spelled using both
+# lower and upper case letters, but some are case sensitive. This
+# makes a big difference for user_max_ip ACL processing and similar.
+# auth_param basic casesensitive off
+#
+# === Parameters for the digest scheme follow ===
+#
+# "program" cmdline
+# Specify the command for the external authenticator. Such
+# a program reads a line containing "username":"realm" and
+# replies with the appropriate H(A1) value hex encoded or
+# ERR if the user (or his H(A1) hash) does not exists.
+# See rfc 2616 for the definition of H(A1).
+# "ERR" responses may optionally be followed by a error description
+# available as %m in the returned error page.
+#
+# By default, the digest authentication scheme is not used unless a
+# program is specified.
+#
+# If you want to use a digest authenticator, set this line to
+# something like
+#
+# auth_param digest program /usr/lib/squid3/digest_pw_auth /usr/etc/digpass
+#
+# "utf8" on|off
+# HTTP uses iso-latin-1 as characterset, while some authentication
+# backends such as LDAP expects UTF-8. If this is set to on Squid will
+# translate the HTTP iso-latin-1 charset to UTF-8 before sending the
+# username & password to the helper.
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to
+# process a backlog of H(A1) calculations, slowing it down.
+# When the H(A1) calculations are done via a (slow) network
+# you are likely to need lots of authenticator processes.
+# auth_param digest children 5
+#
+# "realm" realmstring
+# Specifies the realm name which is to be reported to the
+# client for the digest proxy authentication scheme (part of
+# the text the user will see when prompted their username and
+# password). There is no default.
+# auth_param digest realm Squid proxy-caching web server
+#
+# "nonce_garbage_interval" timeinterval
+# Specifies the interval that nonces that have been issued
+# to client_agent's are checked for validity.
+#
+# "nonce_max_duration" timeinterval
+# Specifies the maximum length of time a given nonce will be
+# valid for.
+#
+# "nonce_max_count" number
+# Specifies the maximum number of times a given nonce can be
+# used.
+#
+# "nonce_strictness" on|off
+# Determines if squid requires strict increment-by-1 behavior
+# for nonce counts, or just incrementing (off - for use when
+# useragents generate nonce counts that occasionally miss 1
+# (ie, 1,2,4,6)). Default off.
+#
+# "check_nonce_count" on|off
+# This directive if set to off can disable the nonce count check
+# completely to work around buggy digest qop implementations in
+# certain mainstream browser versions. Default on to check the
+# nonce count to protect from authentication replay attacks.
+#
+# "post_workaround" on|off
+# This is a workaround to certain buggy browsers who sends
+# an incorrect request digest in POST requests when reusing
+# the same nonce as acquired earlier on a GET request.
+#
+# === NTLM scheme options follow ===
+#
+# "program" cmdline
+# Specify the command for the external NTLM authenticator.
+# Such a program reads exchanged NTLMSSP packets with
+# the browser via Squid until authentication is completed.
+# If you use an NTLM authenticator, make sure you have 1 acl
+# of type proxy_auth. By default, the NTLM authenticator_program
+# is not used.
+#
+# auth_param ntlm program /usr/lib/squid3/ntlm_auth
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to
+# process a backlog of credential verifications, slowing it
+# down. When credential verifications are done via a (slow)
+# network you are likely to need lots of authenticator
+# processes.
+#
+# auth_param ntlm children 5
+#
+# "keep_alive" on|off
+# Whether to keep the connection open after the initial response where
+# Squid tells the browser which schemes are supported by the proxy.
+# Some browsers are known to present many login popups or to corrupt
+# POST/PUT requests transfer if the connection is not closed.
+# The default is currently OFF to avoid this, but may change.
+#
+# auth_param ntlm keep_alive on
+#
+# === Options for configuring the NEGOTIATE auth-scheme follow ===
+#
+# "program" cmdline
+# Specify the command for the external Negotiate authenticator.
+# This protocol is used in Microsoft Active-Directory enabled setups with
+# the Microsoft Internet Explorer or Mozilla Firefox browsers.
+# Its main purpose is to exchange credentials with the Squid proxy
+# using the Kerberos mechanisms.
+# If you use a Negotiate authenticator, make sure you have at least
+# one acl of type proxy_auth active. By default, the negotiate
+# authenticator_program is not used.
+# The only supported program for this role is the ntlm_auth
+# program distributed as part of Samba, version 4 or later.
+#
+# auth_param negotiate program /usr/lib/squid3/ntlm_auth --helper-protocol=gss-spnego
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn (no default).
+# If you start too few Squid will have to wait for them to
+# process a backlog of credential verifications, slowing it
+# down. When crendential verifications are done via a (slow)
+# network you are likely to need lots of authenticator
+# processes.
+# auth_param negotiate children 5
+#
+# "keep_alive" on|off
+# Whether to keep the connection open after the initial response where
+# Squid tells the browser which schemes are supported by the proxy.
+# Some browsers are known to present many login popups or to corrupt
+# POST/PUT requests transfer if the connection is not closed.
+# The default is currently OFF to avoid this, but may change.
+#
+# auth_param negotiate keep_alive on
+#
+#
+# Examples:
+#
+##Recommended minimum configuration per scheme:
+##auth_param negotiate program <uncomment and complete this line to activate>
+##auth_param negotiate children 5
+##auth_param negotiate keep_alive on
+##
+##auth_param ntlm program <uncomment and complete this line to activate>
+##auth_param ntlm children 5
+##auth_param ntlm keep_alive on
+##
+##auth_param digest program <uncomment and complete this line>

+##
+##auth_param basic program <uncomment and complete this line>
+##auth_param basic children 5
+##auth_param basic realm Squid proxy-caching web server
+##auth_param basic credentialsttl 2 hours
+#Default:
+# none
+
+# TAG: authenticate_cache_garbage_interval
+# The time period between garbage collection across the username cache.
+# This is a tradeoff between memory utilization (long intervals - say
+# 2 days) and CPU (short intervals - say 1 minute). Only change if you
+# have good reason to.
+#Default:
+# authenticate_cache_garbage_interval 1 hour
+
+# TAG: authenticate_ttl
+# The time a user & their credentials stay in the logged in
+# user cache since their last request. When the garbage
+# interval passes, all user credentials that have passed their
+# TTL are removed from memory.
+#Default:
+# authenticate_ttl 1 hour
+
+# TAG: authenticate_ip_ttl
+# If you use proxy authentication and the 'max_user_ip' ACL,
+# this directive controls how long Squid remembers the IP
+# addresses associated with each user. Use a small value
+# (e.g., 60 seconds) if your users might change addresses
+# quickly, as is the case with dialups. You might be safe
+# using a larger value (e.g., 2 hours) in a corporate LAN
+# environment with relatively static address assignments.
+#Default:
+# authenticate_ip_ttl 0 seconds
+
+# ACCESS CONTROLS
+# -----------------------------------------------------------------------------

+# TAG: follow_x_forwarded_for
+# Allowing or Denying the X-Forwarded-For header to be followed to
+# find the original source of a request.
+#
+# Requests may pass through a chain of several other proxies
+# before reaching us. The X-Forwarded-For header will contain a
+# comma-separated list of the IP addresses in the chain, with the
+# rightmost address being the most recent.
+#
+# If a request reaches us from a source that is allowed by this
+# configuration item, then we consult the X-Forwarded-For header
+# to see where that host received the request from. If the
+# X-Forwarded-For header contains multiple addresses, we continue
+# backtracking until we reach an address for which we are not allowed
+# to follow the X-Forwarded-For header, or until we reach the first
+# address in the list. For the purpose of ACL used in the
+# follow_x_forwarded_for directive the src ACL type always matches
+# the address we are testing and srcdomain matches its rDNS.
+#
+# The end result of this process is an IP address that we will
+# refer to as the indirect client address. This address may
+# be treated as the client address for access control, ICAP, delay
+# pools and logging, depending on the acl_uses_indirect_client,
+# icap_uses_indirect_client, delay_pool_uses_indirect_client and

+# SECURITY CONSIDERATIONS:
+#
+# Any host for which we follow the X-Forwarded-For header
+# can place incorrect information in the header, and Squid
+# will use the incorrect information as if it were the
+# source address of the request. This may enable remote
+# hosts to bypass any access control restrictions that are
+# based on the client's source addresses.

+# IPv6 Magic:

+#
+# To operate with tcp_outgoing_address and keep the bridging benefits
+# an additional ACL needs to be used which ensures the IPv6-bound traffic
+# is never forced or permitted out the IPv4 interface.
+#
+# # IPv6 destination test along with a dummy access control to perform the required DNS
+# # This MUST be place before any ALLOW rules.

+#
+# 'dst ipv6' is a slow ACL. It will only work here if 'dst' is used

+# OPTIONS WHICH AFFECT THE NEIGHBOR SELECTION ALGORITHM
+# -----------------------------------------------------------------------------
+
+# TAG: cache_peer
+# To specify other caches in a hierarchy, use the format:
+#
+# cache_peer hostname type http-port icp-port [options]
+#
+# For example,
+#
+# # proxy icp
+# # hostname type port port options
+# # -------------------- -------- ----- ----- -----------
+# cache_peer parent.foo.net parent 3128 3130 default
+# cache_peer sib1.foo.net sibling 3128 3130 proxy-only
+# cache_peer sib2.foo.net sibling 3128 3130 proxy-only
+# cache_peer example.com parent 80 0 default
+# cache_peer cdn.example.com sibling 3128 0
+#
+# type: either 'parent', 'sibling', or 'multicast'.
+#
+# proxy-port: The port number where the peer accept HTTP requests.
+# For other Squid proxies this is usually 3128
+# For web servers this is usually 80
+#
+# icp-port: Used for querying neighbor caches about objects.
+# Set to 0 if the peer does not support ICP or HTCP.
+# See ICP and HTCP options below for additional details.
+#
+#
+# ==== ICP OPTIONS ====
+#
+# You MUST also set icp_port and icp_access explicitly when using these options.
+# The defaults will prevent peer traffic using ICP.
+#
+#
+# no-query Disable ICP queries to this neighbor.
+#
+# multicast-responder
+# Indicates the named peer is a member of a multicast group.
+# ICP queries will not be sent directly to the peer, but ICP
+# replies will be accepted from it.
+#
+# closest-only Indicates that, for ICP_OP_MISS replies, we'll only forward
+# CLOSEST_PARENT_MISSes and never FIRST_PARENT_MISSes.
+#
+# background-ping
+# To only send ICP queries to this neighbor infrequently.
+# This is used to keep the neighbor round trip time updated
+# and is usually used in conjunction with weighted-round-robin.
+#
+#
+# ==== HTCP OPTIONS ====
+#
+# You MUST also set htcp_port and htcp_access explicitly when using these options.
+# The defaults will prevent peer traffic using HTCP.
+#
+#
+# htcp Send HTCP, instead of ICP, queries to the neighbor.
+# You probably also want to set the "icp-port" to 4827
+# instead of 3130.
+#
+# htcp-oldsquid Send HTCP to old Squid versions.
+#
+# htcp-no-clr Send HTCP to the neighbor but without
+# sending any CLR requests. This cannot be used with
+# htcp-only-clr.
+#
+# htcp-only-clr Send HTCP to the neighbor but ONLY CLR requests.
+# This cannot be used with htcp-no-clr.
+#
+# htcp-no-purge-clr
+# Send HTCP to the neighbor including CLRs but only when
+# they do not result from PURGE requests.
+#
+# htcp-forward-clr
+# Forward any HTCP CLR requests this proxy receives to the peer.
+#
+#
+# ==== PEER SELECTION METHODS ====
+#
+# The default peer selection method is ICP, with the first responding peer
+# being used as source. These options can be used for better load balancing.
+#
+#
+# default This is a parent cache which can be used as a "last-resort"
+# if a peer cannot be located by any of the peer-selection methods.
+# If specified more than once, only the first is used.
+#
+# round-robin Load-Balance parents which should be used in a round-robin
+# fashion in the absence of any ICP queries.
+# weight=N can be used to add bias.
+#
+# weighted-round-robin
+# Load-Balance parents which should be used in a round-robin
+# fashion with the frequency of each parent being based on the
+# round trip time. Closer parents are used more often.
+# Usually used for background-ping parents.
+# weight=N can be used to add bias.
+#
+# carp Load-Balance parents which should be used as a CARP array.
+# The requests will be distributed among the parents based on the
+# CARP load balancing hash function based on their weight.
+#
+# userhash Load-balance parents based on the client proxy_auth or ident username.
+#
+# sourcehash Load-balance parents based on the client source IP.
+#
+# multicast-siblings
+# To be used only for cache peers of type "multicast".
+# ALL members of this multicast group have "sibling"
+# relationship with it, not "parent". This is to a multicast
+# group when the requested object would be fetched only from
+# a "parent" cache, anyway. It's useful, e.g., when
+# configuring a pool of redundant Squid proxies, being
+# members of the same multicast group.
+#
+#
+# ==== PEER SELECTION OPTIONS ====
+#
+# weight=N use to affect the selection of a peer during any weighted
+# peer-selection mechanisms.
+# The weight must be an integer; default is 1,
+# larger weights are favored more.
+# This option does not affect parent selection if a peering
+# protocol is not in use.
+#
+# basetime=N Specify a base amount to be subtracted from round trip
+# times of parents.
+# It is subtracted before division by weight in calculating
+# which parent to fectch from. If the rtt is less than the
+# base time the rtt is set to a minimal value.
+#
+# ttl=N Specify a TTL to use when sending multicast ICP queries
+# to this address.
+# Only useful when sending to a multicast group.
+# Because we don't accept ICP replies from random
+# hosts, you must configure other group members as
+# peers with the 'multicast-responder' option.
+#
+# no-delay To prevent access to this neighbor from influencing the
+# delay pools.
+#
+# digest-url=URL Tell Squid to fetch the cache digest (if digests are
+# enabled) for this host from the specified URL rather
+# than the Squid default location.
+#
+#
+# ==== ACCELERATOR / REVERSE-PROXY OPTIONS ====
+#
+# originserver Causes this parent to be contacted as an origin server.
+# Meant to be used in accelerator setups when the peer
+# is a web server.
+#
+# forceddomain=name
+# Set the Host header of requests forwarded to this peer.
+# Useful in accelerator setups where the server (peer)
+# expects a certain domain name but clients may request
+# others. ie example.com or www.example.com
+#
+# no-digest Disable request of cache digests.
+#
+# no-netdb-exchange
+# Disables requesting ICMP RTT database (NetDB).
+#
+#
+# ==== AUTHENTICATION OPTIONS ====
+#
+# login=user:password
+# If this is a personal/workgroup proxy and your parent
+# requires proxy authentication.
+#
+# Note: The string can include URL escapes (i.e. %20 for
+# spaces). This also means % must be written as %%.
+#
+# login=PROXYPASS
+# Send login details received from client to this peer.
+# Authentication is not required, nor changed.
+#
+# Note: This will pass any form of authentication but
+# only Basic auth will work through a proxy unless the
+# connection-auth options are also used.
+#
+# login=PASS Send login details received from client to this peer.
+# Authentication is not required by this option.
+# If there are no client-provided authentication headers
+# to pass on, but username and password are available
+# from either proxy login or an external ACL user= and
+# password= result tags they may be sent instead.
+#
+# Note: To combine this with proxy_auth both proxies must
+# share the same user database as HTTP only allows for
+# a single login (one for proxy, one for origin server).
+# Also be warned this will expose your users proxy
+# password to the peer. USE WITH CAUTION
+#
+# login=*:password
+# Send the username to the upstream cache, but with a
+# fixed password. This is meant to be used when the peer
+# is in another administrative domain, but it is still
+# needed to identify each user.
+# The star can optionally be followed by some extra
+# information which is added to the username. This can
+# be used to identify this proxy to the peer, similar to
+# the login=username:password option above.
+#
+# connection-auth=on|off
+# Tell Squid that this peer does or not support Microsoft
+# connection oriented authentication, and any such
+# challenges received from there should be ignored.
+# Default is auto to automatically determine the status
+# of the peer.
+#
+#
+# ==== SSL / HTTPS / TLS OPTIONS ====
+#
+# ssl Encrypt connections to this peer with SSL/TLS.
+#
+# sslcert=/path/to/ssl/certificate
+# A client SSL certificate to use when connecting to
+# this peer.
+#
+# sslkey=/path/to/ssl/key

+# a more complete list.
+#
+# sslcafile=... A file containing additional CA certificates to use

+#
+# sslcapath=... A directory containing additional CA certificates to
+# use when verifying the peer certificate.
+#

+# DONT_VERIFY_PEER
+# Accept certificates even if they fail to
+# verify.
+# NO_DEFAULT_CA
+# Don't use the default CA list built in

+# DONT_VERIFY_DOMAIN
+# Don't verify the peer certificate
+# matches the server name
+#
+# ssldomain= The peer name as advertised in it's certificate.

+# See MS KB document Q307347 for details on this header.
+# If set to auto the header will only be added if the

+#
+#
+# ==== GENERAL OPTIONS ====
+#
+# connect-timeout=N
+# A peer-specific connect timeout.
+# Also see the peer_connect_timeout directive.
+#
+# connect-fail-limit=N
+# How many times connecting to a peer must fail before
+# it is marked as down. Default is 10.
+#
+# allow-miss Disable Squid's use of only-if-cached when forwarding
+# requests to siblings. This is primarily useful when
+# icp_hit_stale is used by the sibling. To extensive use
+# of this option may result in forwarding loops, and you
+# should avoid having two-way peerings with this option.
+# For example to deny peer usage on requests from peer
+# by denying cache_peer_access if the source is a peer.
+#
+# max-conn=N Limit the amount of connections Squid may open to this
+# peer. see also
+#
+# name=xxx Unique name for the peer.
+# Required if you have multiple peers on the same host
+# but different ports.
+# This name can be used in cache_peer_access and similar
+# directives to dentify the peer.
+# Can be used by outgoing access controls through the
+# peername ACL type.
+#
+# no-tproxy Do not use the client-spoof TPROXY support when forwarding
+# requests to this peer. Use normal address selection instead.
+#
+# proxy-only objects fetched from the peer will not be stored locally.
+#
+#Default:
+# none
+
+# TAG: cache_peer_domain
+# Use to limit the domains for which a neighbor cache will be
+# queried. Usage:
+#
+# cache_peer_domain cache-host domain [domain ...]
+# cache_peer_domain cache-host !domain
+#
+# For example, specifying
+#
+# cache_peer_domain parent.foo.net .edu
+#
+# has the effect such that UDP query packets are sent to
+# 'bigserver' only when the requested object exists on a
+# server in the .edu domain. Prefixing the domainname
+# with '!' means the cache will be queried for objects
+# NOT in that domain.
+#
+# NOTE: * Any number of domains may be given for a cache-host,
+# either on the same or separate lines.
+# * When multiple domains are given for a particular
+# cache-host, the first matched domain is applied.
+# * Cache hosts with no domain restrictions are queried
+# for all requests.
+# * There are no defaults.
+# * There is also a 'cache_peer_access' tag in the ACL
+# section.
+#Default:
+# none
+
+# TAG: cache_peer_access
+# Similar to 'cache_peer_domain' but provides more flexibility by
+# using ACL elements.
+#
+# cache_peer_access cache-host allow|deny [!]aclname ...
+#
+# The syntax is identical to 'http_access' and the other lists of
+# ACL elements. See the comments for 'http_access' below, or
+# the Squid FAQ (http://wiki.squid-cache.org/SquidFaq/SquidAcl).
+#Default:
+# none
+
+# TAG: neighbor_type_domain
+# usage: neighbor_type_domain neighbor parent|sibling domain domain ...
+#
+# Modifying the neighbor type for specific domains is now
+# possible. You can treat some domains differently than the the
+# default neighbor type specified on the 'cache_peer' line.
+# Normally it should only be necessary to list domains which
+# should be treated differently because the default neighbor type
+# applies for hostnames which do not match domains listed here.
+#
+#EXAMPLE:
+# cache_peer cache.foo.org parent 3128 3130
+# neighbor_type_domain cache.foo.org sibling .com .net
+# neighbor_type_domain cache.foo.org sibling .au .de
+#Default:
+# none
+
+# TAG: dead_peer_timeout (seconds)
+# This controls how long Squid waits to declare a peer cache
+# as "dead." If there are no ICP replies received in this
+# amount of time, Squid will declare the peer dead and not
+# expect to receive any further ICP replies. However, it
+# continues to send ICP queries, and will mark the peer as
+# alive upon receipt of the first subsequent ICP reply.
+#
+# This timeout also affects when Squid expects to receive ICP
+# replies from peers. If more than 'dead_peer' seconds have
+# passed since the last ICP reply was received, Squid will not
+# expect to receive an ICP reply on the next query. Thus, if
+# your time between requests is greater than this timeout, you
+# will see a lot of requests sent DIRECT to origin servers
+# instead of to your parents.
+#Default:
+# dead_peer_timeout 10 seconds
+
+# TAG: forward_max_tries
+# Controls how many different forward paths Squid will try
+# before giving up. See also forward_timeout.
+#Default:
+# forward_max_tries 10
+
+# TAG: hierarchy_stoplist
+# A list of words which, if found in a URL, cause the object to
+# be handled directly by this cache. In other words, use this
+# to not query neighbor caches for certain objects. You may
+# list this option multiple times.
+#
+# Example:
+# hierarchy_stoplist cgi-bin ?
+#
+# Note: never_direct overrides this option.
+#Default:
+# none
+
+# MEMORY CACHE OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: cache_mem (bytes)
+# NOTE: THIS PARAMETER DOES NOT SPECIFY THE MAXIMUM PROCESS SIZE.
+# IT ONLY PLACES A LIMIT ON HOW MUCH ADDITIONAL MEMORY SQUID WILL
+# USE AS A MEMORY CACHE OF OBJECTS. SQUID USES MEMORY FOR OTHER
+# THINGS AS WELL. SEE THE SQUID FAQ SECTION 8 FOR DETAILS.
+#
+# 'cache_mem' specifies the ideal amount of memory to be used
+# for:
+# * In-Transit objects
+# * Hot Objects
+# * Negative-Cached objects
+#
+# Data for these objects are stored in 4 KB blocks. This
+# parameter specifies the ideal upper limit on the total size of
+# 4 KB blocks allocated. In-Transit objects take the highest
+# priority.
+#
+# In-transit objects have priority over the others. When
+# additional space is needed for incoming data, negative-cached
+# and hot objects will be released. In other words, the
+# negative-cached and hot objects will fill up any unused space
+# not needed for in-transit objects.
+#
+# If circumstances require, this limit will be exceeded.
+# Specifically, if your incoming request rate requires more than
+# 'cache_mem' of memory to hold in-transit objects, Squid will
+# exceed this limit to satisfy the new requests. When the load
+# decreases, blocks will be freed until the high-water mark is
+# reached. Thereafter, blocks will be used to store hot
+# objects.
+#Default:
+# cache_mem 256 MB
+
+# TAG: maximum_object_size_in_memory (bytes)
+# Objects greater than this size will not be attempted to kept in
+# the memory cache. This should be set high enough to keep objects
+# accessed frequently in memory to improve performance whilst low
+# enough to keep larger objects from hoarding cache_mem.
+#Default:
+# maximum_object_size_in_memory 512 KB
+
+# TAG: memory_replacement_policy

+
+# DISK CACHE OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: cache_replacement_policy
+# The cache replacement policy parameter determines which
+# objects are evicted (replaced) when disk space is needed.
+#
+# lru : Squid's original list based LRU policy
+# heap GDSF : Greedy-Dual Size Frequency
+# heap LFUDA: Least Frequently Used with Dynamic Aging
+# heap LRU : LRU policy implemented using a heap
+#
+# Applies to any cache_dir lines listed below this.
+#
+# The LRU policies keeps recently referenced objects.
+#
+# The heap GDSF policy optimizes object hit rate by keeping smaller
+# popular objects in cache so it has a better chance of getting a
+# hit. It achieves a lower byte hit rate than LFUDA though since
+# it evicts larger (possibly popular) objects.
+#
+# The heap LFUDA policy keeps popular objects in cache regardless of
+# their size and thus optimizes byte hit rate at the expense of
+# hit rate since one large, popular object will prevent many
+# smaller, slightly less popular objects from being cached.
+#
+# Both policies utilize a dynamic aging mechanism that prevents
+# cache pollution that can otherwise occur with frequency-based
+# replacement policies.
+#
+# NOTE: if using the LFUDA replacement policy you should increase
+# the value of maximum_object_size above its default of 4096 KB to
+# to maximize the potential byte hit rate improvement of LFUDA.

+# Usage:
+#
+# cache_dir Type Directory-Name Fs-specific-data [options]
+#
+# You can specify multiple cache_dir lines to spread the

+#
+# Type specifies the kind of storage system to use. Only "ufs"
+# is built by default. To enable any of the other storage systems
+# see the --enable-storeio configure option.
+#
+# 'Directory' is a top-level directory where cache swap
+# files will be stored. If you want to use an entire disk
+# for caching, this can be the mount-point directory.
+# The directory must exist and be writable by the Squid
+# process. Squid will NOT create this directory for you.
+#
+# The ufs store type:
+#
+# "ufs" is the old well-known Squid storage format that has always
+# been there.
+#
+# cache_dir ufs Directory-Name Mbytes L1 L2 [options]
+#
+# 'Mbytes' is the amount of disk space (MB) to use under this
+# directory. The default is 100 MB. Change this to suit your
+# configuration. Do NOT put the size of your disk drive here.
+# Instead, if you want Squid to use the entire disk drive,
+# subtract 20% and use that value.
+#
+# 'L1' is the number of first-level subdirectories which
+# will be created under the 'Directory'. The default is 16.
+#
+# 'L2' is the number of second-level subdirectories which
+# will be created under each first-level directory. The default
+# is 256.
+#
+# The aufs store type:
+#
+# "aufs" uses the same storage format as "ufs", utilizing
+# POSIX-threads to avoid blocking the main Squid process on
+# disk-I/O. This was formerly known in Squid as async-io.
+#
+# cache_dir aufs Directory-Name Mbytes L1 L2 [options]
+#
+# see argument descriptions under ufs above

+# separate process to avoid blocking the main Squid process on
+# disk-I/O.
+#
+# cache_dir diskd Directory-Name Mbytes L1 L2 [options] [Q1=n] [Q2=n]
+#
+# see argument descriptions under ufs above
+#
+# Q1 specifies the number of unacknowledged I/O requests when Squid
+# stops opening new files. If this many messages are in the queues,
+# Squid won't open new files. Default is 64
+#
+# Q2 specifies the number of unacknowledged messages when Squid
+# starts blocking. If this many messages are in the queues,

+#
+# When Q1 < Q2 (the default), the cache directory is optimized

+# time.
+#
+# The coss store type:

+# NP: COSS filesystem in Squid-3 has been deemed too unstable for
+# production use and has thus been removed from this release.
+# We hope that it can be made usable again soon.
+#
+# block-size=n defines the "block size" for COSS cache_dir's.
+# Squid uses file numbers as block numbers. Since file numbers
+# are limited to 24 bits, the block size determines the maximum
+# size of the COSS partition. The default is 512 bytes, which
+# leads to a maximum cache_dir size of 512<<24, or 8 GB. Note
+# you should not change the coss block size after Squid
+# has written some objects to the cache_dir.
+#
+# The coss file store has changed from 2.5. Now it uses a file
+# called 'stripe' in the directory names in the config - and
+# this will be created by squid -z.
+#
+# Common options:
+#
+# no-store, no new objects should be stored to this cache_dir
+#
+# max-size=n, refers to the max object size in bytes this cache_dir
+# supports. It is used to select the cache_dir to store the object.
+# Note: To make optimal use of the max-size limits you should order
+# the cache_dir lines with the smallest max-size value first and the
+# ones with no max-size specification last.
+#
+# Note for coss, max-size must be less than COSS_MEMBUF_SZ,
+# which can be changed with the --with-coss-membuf-size=N configure
+# option.

+# This specifies the maximum size for HTTP headers in a reply.
+# Reply headers are usually relatively small (about 512 bytes).
+# Placing a limit on the reply header size will catch certain

+# buffer-overflow or denial-of-service attacks.
+#Default:
+# reply_header_max_size 64 KB
+
+# TAG: request_body_max_size (bytes)
+# This specifies the maximum size for an HTTP request body.
+# In other words, the maximum size of a PUT/POST request.
+# A user who attempts to send a request with a body larger
+# than this limit receives an "Invalid Request" error message.

+# TAG: client_request_buffer_max_size (bytes)

+
+# TAG: chunked_request_body_max_size (bytes)
+# A broken or confused HTTP/1.1 client may send a chunked HTTP
+# request to Squid. Squid does not have full support for that
+# feature yet. To cope with such requests, Squid buffers the
+# entire request and then dechunks request body to create a
+# plain HTTP/1.0 request with a known content length. The plain
+# request is then used by the rest of Squid code as usual.
+#
+# The option value specifies the maximum size of the buffer used
+# to hold the request before the conversion. If the chunked
+# request size exceeds the specified limit, the conversion
+# fails, and the client receives an "unsupported request" error,
+# as if dechunking was disabled.
+#
+# Dechunking is enabled by default. To disable conversion of
+# chunked requests, set the maximum to zero.
+#
+# Request dechunking feature and this option in particular are a
+# temporary hack. When chunking requests and responses are fully

+#
+# Quote from RFC2616 section 4.1 on this matter:
+#
+# Note: certain buggy HTTP/1.0 client implementations generate an
+# extra CRLF's after a POST request. To restate what is explicitly
+# forbidden by the BNF, an HTTP/1.1 client must not preface or follow

+# TAG: ie_refresh on|off
+# Microsoft Internet Explorer up until version 5.5 Service
+# Pack 1 has an issue with transparent proxies, wherein it
+# is impossible to force a refresh. Turning this on provides
+# a partial fix to the problem, by causing all IMS-REFRESH
+# requests from older IE versions to check the origin server
+# for fresh content. This reduces hit ratio by some amount
+# (~10% in my experience), but allows users to actually get
+# fresh content when they want it. Note because Squid
+# cannot tell if the user is using 5.5 or 5.5SP1, the behavior
+# of 5.5 is unchanged from old versions of Squid (i.e. a
+# forced refresh is impossible). Newer versions of IE will,
+# hopefully, continue to have the new behavior and will be
+# handled based on that assumption. This option defaults to
+# the old Squid behavior, which is better for hit ratios but
+# worse for clients using IE, if they need to be able to

+# delay pools, one of class 2 and one of class 3, the settings above
+# and here would be:
+#
+# Example:
+# delay_pools 4 # 4 delay pools
+# delay_class 1 2 # pool 1 is a class 2 pool
+# delay_class 2 3 # pool 2 is a class 3 pool
+# delay_class 3 4 # pool 3 is a class 4 pool
+# delay_class 4 5 # pool 4 is a class 5 pool
+#
+# The delay pool classes are:

+# maximum number of bytes which can be in the bucket at any time.
+#
+# There must be one delay_parameters line for each delay pool.
+#
+#
+# For example, if delay pool number 1 is a class 2 delay pool as in the
+# above example, and is being used to strictly limit each host to 64Kbit/sec
+# (plus overheads), with no overall limit, the line is:

+#
+# Note that 8 x 8000 KByte/sec -> 64Kbit/sec.
+#
+# Note that the figure -1 is used to represent "unlimited".
+#
+#
+# And, if delay pool number 2 is a class 3 delay pool as in the above
+# example, and you want to limit it to a total of 256Kbit/sec (strict limit)
+# with each 8-bit network permitted 64Kbit/sec (strict limit) and each
+# individual host permitted 4800bit/sec with a bucket maximum size of 64Kbits
+# to permit a decent web page to be downloaded at a decent speed
+# (if the network is not being limited due to overuse) but slow down

+# 8 x 8000 KByte/sec -> 64Kbit/sec.
+# 8 x 600 Byte/sec -> 4800bit/sec.
+#
+#
+# Finally, for a class 4 delay pool as in the example - each user will
+# be limited to 128Kbits/sec no matter how many workstations they are logged into.:

+# acl it evaluated in http_access, and if a 'deny_info' line exists
+# for that ACL Squid returns a corresponding error page.
+#
+# The acl is typically the last acl on the http_access deny line which
+# denied access. The exceptions to this rule are:
+# - When Squid needs to request authentication credentials. It's then
+# the first authentication related acl encountered
+# - When none of the http_access lines matches. It's then the last
+# acl processed on the last http_access line.
+#
+# NP: If providing your own custom error pages with error_directory
+# you may also specify them by your custom file name:
+# Example: deny_info ERR_CUSTOM_ACCESS_DENIED bad_guys
+#
+# Alternatively you can specify an error URL. The browsers will
+# get redirected (302 or 307) to the specified URL. %s in the redirection
+# URL will be replaced by the requested URL.
+#
+# Alternatively you can tell Squid to reset the TCP connection
+# by specifying TCP_RESET.

+
+# OPTIONS INFLUENCING REQUEST FORWARDING
+# -----------------------------------------------------------------------------
+
+# TAG: nonhierarchical_direct
+# By default, Squid will send any non-hierarchical requests
+# (matching hierarchy_stoplist or not cacheable request type) direct
+# to origin servers.
+#
+# If you set this to off, Squid will prefer to send these
+# requests to parents.
+#
+# Note that in most configurations, by turning this off you will only
+# add latency to these request without any improvement in global hit
+# ratio.
+#
+# If you are inside an firewall see never_direct instead of
+# this directive.
+#Default:
+# nonhierarchical_direct on
+
+# TAG: prefer_direct
+# Normally Squid tries to use parents for most requests. If you for some
+# reason like it to first try going direct and only use a parent if
+# going direct fails set this to on.
+#
+# By combining nonhierarchical_direct off and prefer_direct on you
+# can set up Squid to use a parent as a backup path if going direct
+# fails.
+#
+# Note: If you want Squid to use parents for all requests see
+# the never_direct directive. prefer_direct only modifies how Squid
+# acts on cacheable requests.
+#Default:
+# prefer_direct off
+
+# TAG: always_direct
+# Usage: always_direct allow|deny [!]aclname ...
+#
+# Here you can use ACL elements to specify requests which should
+# ALWAYS be forwarded by Squid to the origin servers without using
+# any peers. For example, to always directly forward requests for
+# local servers ignoring any parents or siblings you may have use
+# something like:
+#
+# acl local-servers dstdomain my.domain.net
+# always_direct allow local-servers
+#
+# To always forward FTP requests directly, use
+#
+# acl FTP proto FTP
+# always_direct allow FTP
+#
+# NOTE: There is a similar, but opposite option named
+# 'never_direct'. You need to be aware that "always_direct deny
+# foo" is NOT the same thing as "never_direct allow foo". You
+# may need to use a deny rule to exclude a more-specific case of
+# some other rule. Example:
+#
+# acl local-external dstdomain external.foo.net
+# acl local-servers dstdomain .foo.net
+# always_direct deny local-external
+# always_direct allow local-servers
+#
+# NOTE: If your goal is to make the client forward the request
+# directly to the origin server bypassing Squid then this needs
+# to be done in the client configuration. Squid configuration
+# can only tell Squid how Squid should fetch the object.
+#
+# NOTE: This directive is not related to caching. The replies
+# is cached as usual even if you use always_direct. To not cache
+# the replies see the 'cache' directive.
+#
+# This clause supports both fast and slow acl types.
+# See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
+#Default:
+# none
+
+# TAG: never_direct
+# Usage: never_direct allow|deny [!]aclname ...
+#
+# never_direct is the opposite of always_direct. Please read
+# the description for always_direct if you have not already.
+#
+# With 'never_direct' you can use ACL elements to specify
+# requests which should NEVER be forwarded directly to origin
+# servers. For example, to force the use of a proxy for all
+# requests, except those in your local domain use something like:
+#
+# acl local-servers dstdomain .foo.net
+# never_direct deny local-servers
+# never_direct allow all
+#
+# or if Squid is inside a firewall and there are local intranet
+# servers inside the firewall use something like:
+#
+# acl local-intranet dstdomain .foo.net
+# acl local-external dstdomain external.foo.net
+# always_direct deny local-external
+# always_direct allow local-intranet
+# never_direct allow all
+#

+# The file is checked at startup and upon configuration.
+# If set to 'none', it won't be checked.
+# If append_domain is used, that domain will be added to
+# domain-local (i.e. not containing any dot character) host

+
+# TAG: append_domain
+# Appends local domain name to hostnames without any dots in

+# cause some Internet sites to become unavailable.
+#
+#Example:
+# append_domain .yourdomain.com
+#Default:
+# none
+
+# TAG: ignore_unknown_nameservers
+# By default Squid checks that DNS responses are received
+# from the same IP addresses they are sent to. If they
+# don't match, Squid ignores the response and writes a warning
+# message to cache.log. You can allow responses from unknown
+# nameservers by setting this option to 'off'.
+#Default:
+# ignore_unknown_nameservers on
+
+# TAG: dns_v4_fallback
+# Standard practice with DNS is to lookup either A or AAAA records
+# and use the results if it succeeds. Only looking up the other if
+# the first attempt fails or otherwise produces no results.
+#
+# That policy however will cause squid to produce error pages for some
+# servers that advertise AAAA but are unreachable over IPv6.
+#
+# If this is ON squid will always lookup both AAAA and A, using both.
+# If this is OFF squid will lookup AAAA and only try A if none found.
+#
+# WARNING: There are some possibly unwanted side-effects with this on:
+# *) Doubles the load placed by squid on the DNS network.
+# *) May negatively impact connection delay times.
+#Default:
+# dns_v4_fallback on
+
+# TAG: dns_v4_first
+# With the IPv6 Internet being as fast or faster than IPv4 Internet
+# for most networks Squid prefers to contact websites over IPv6.
+#
+# This option reverses the order of preference to make Squid contact
+# dual-stack websites over IPv4 first. Squid will still perform both
+# IPv6 and IPv4 DNS lookups before connecting.
+#
+# WARNING:
+# This option will restrict the situations under which IPv6
+# connectivity is used (and tested), potentially hiding network
+# problem swhich would otherwise be detected and warned about.

+
+# TAG: ipcache_size (number of entries)
+#Default:
+# ipcache_size 1024
+

+
+# TAG: memory_pools on|off
+# If set, Squid will keep pools of allocated (but unused) memory
+# available for future use. If memory is a premium on your
+# system and you believe your malloc library outperforms Squid
+# routines, disable this.
+#Default:
+# memory_pools on
+
+# TAG: memory_pools_limit (bytes)
+# Used only with memory_pools on:
+# memory_pools_limit 50 MB
+#
+# If set to a non-zero value, Squid will keep at most the specified
+# limit of allocated (but unused) memory in memory pools. All free()
+# requests that exceed this limit will be handled by your malloc
+# library. Squid does not pre-allocate any memory, just safe-keeps
+# objects that otherwise would be free()d. Thus, it is safe to set
+# memory_pools_limit to a reasonably high value even if your
+# configuration will use less memory.
+#
+# If set to none, Squid will keep all memory it can. That is, there
+# will be no limit on the total amount of memory used for safe-keeping.
+#
+# To disable memory allocation optimization, do not set
+# memory_pools_limit to 0 or none. Set memory_pools to "off" instead.
+#
+# An overhead for maintaining memory pools is not taken into account
+# when the limit is checked. This overhead is close to four bytes per
+# object kept. However, pools may actually _save_ memory because of
+# reduced memory thrashing in your malloc library.
+#Default:
+# memory_pools_limit 5 MB
+
+# TAG: forwarded_for on|off|transparent|truncate|delete
+# If set to "on", Squid will append your client's IP address
+# in the HTTP requests it forwards. By default it looks like:
+#
+# X-Forwarded-For: 192.1.2.3
+#
+# If set to "off", it will appear as
+#
+# X-Forwarded-For: unknown
+#
+# If set to "transparent", Squid will not alter the
+# X-Forwarded-For header in any way.
+#
+# If set to "delete", Squid will delete the entire
+# X-Forwarded-For header.
+#
+# If set to "truncate", Squid will remove all existing
+# X-Forwarded-For entries, and place itself as the sole entry.
+#Default:
+# forwarded_for on
+
+# TAG: cachemgr_passwd
+# Specify passwords for cachemgr operations.
+#
+# Usage: cachemgr_passwd password action action ...
+#
+# Some valid actions are (see cache manager menu for a full list):
+# 5min
+# 60min
+# asndb
+# authenticator
+# cbdata
+# client_list
+# comm_incoming

+#
+# To disable an action, set the password to "disable".
+# To allow performing an action without a password, set the
+# password to "none".
+#
+# Use the keyword "all" to set the same password for all actions.
+#
+#Example:
+# cachemgr_passwd secret shutdown
+# cachemgr_passwd lesssssssecret info stats/objects
+# cachemgr_passwd disable all
+#Default:
+# none
+
+# TAG: client_db on|off
+# If you want to disable collecting per-client statistics,
+# turn off client_db here.
+#Default:
+# client_db on
+
+# TAG: refresh_all_ims on|off
+# When you enable this option, squid will always check
+# the origin server for an update when a client sends an
+# If-Modified-Since request. Many browsers use IMS
+# requests when the user requests a reload, and this
+# ensures those clients receive the latest version.
+#
+# By default (off), squid may return a Not Modified response
+# based on the age of the cached version.
+#Default:
+# refresh_all_ims off
+
+# TAG: reload_into_ims on|off
+# When you enable this option, client no-cache or ``reload''
+# requests will be changed to If-Modified-Since requests.
+# Doing this VIOLATES the HTTP standard. Enabling this
+# feature could make you liable for problems which it
+# causes.
+#
+# see also refresh_pattern for a more selective approach.
+#Default:
+# reload_into_ims off
+
+# TAG: maximum_single_addr_tries
+# This sets the maximum number of connection attempts for a
+# host that only has one address (for multiple-address hosts,
+# each address is tried once).
+#
+# The default value is one attempt, the (not recommended)
+# maximum is 255 tries. A warning message will be generated
+# if it is set to a value greater than ten.
+#
+# Note: This is in addition to the request re-forwarding which
+# takes place if Squid fails to get a satisfying response.
+#Default:
+# maximum_single_addr_tries 1
+
+# TAG: retry_on_error
+# If set to ON Squid will automatically retry requests when
+# receiving an error response with status 403 (Forbidden),
+# 500 (Internal Error), 501 or 503 (Service not available).
+# Status 502 and 504 (Gateway errors) are always retried.
+#
+# This is mainly useful if you are in a complex cache hierarchy to
+# work around access control errors.
+#
+# NOTE: This retry will attempt to find another working destination.
+# Which is different from the server which just failed.
+#Default:
+# retry_on_error off
+
+# TAG: as_whois_server
+# WHOIS server to query for AS numbers. NOTE: AS numbers are
+# queried only when Squid starts up, not for every request.
+#Default:
+# as_whois_server whois.ra.net
+
+# TAG: offline_mode
+# Enable this option and Squid will never try to validate cached
+# objects.
+#Default:
+# offline_mode off
+
+# TAG: uri_whitespace
+# What to do with requests that have whitespace characters in the
+# URI. Options:
+#
+# strip: The whitespace characters are stripped out of the URL.
+# This is the behavior recommended by RFC2396.
+# deny: The request is denied. The user receives an "Invalid
+# Request" message.
+# allow: The request is allowed and the URI is not changed. The
+# whitespace characters remain in the URI. Note the
+# whitespace is passed to redirector processes if they
+# are in use.
+# encode: The request is allowed and the whitespace characters are
+# encoded according to RFC1738. This could be considered
+# a violation of the HTTP/1.1
+# RFC because proxies are not allowed to rewrite URI's.
+# chop: The request is allowed and the URI is chopped at the
+# first whitespace. This might also be considered a
+# violation.
+#Default:
+# uri_whitespace strip
+
+# TAG: chroot
+# Specifies a directory where Squid should do a chroot() while
+# initializing. This also causes Squid to fully drop root
+# privileges after initializing. This means, for example, if you
+# use a HTTP port less than 1024 and try to reconfigure, you may
+# get an error saying that Squid can not open the port.
+#Default:
+# none
+
+# TAG: balance_on_multiple_ip
+# Modern IP resolvers in squid sort lookup results by preferred access.
+# By default squid will use these IP in order and only rotates to
+# the next listed when the most preffered fails.
+#
+# Some load balancing servers based on round robin DNS have been
+# found not to preserve user session state across requests
+# to different IP addresses.
+#
+# Enabling this directive Squid rotates IP's per request.
+#Default:
+# balance_on_multiple_ip off
+
+# TAG: pipeline_prefetch
+# To boost the performance of pipelined requests to closer
+# match that of a non-proxied environment Squid can try to fetch
+# up to two requests in parallel from a pipeline.
+#
+# Defaults to off for bandwidth management and access logging
+# reasons.
+#
+# WARNING: pipelining breaks NTLM and Negotiate/Kerberos authentication.
+#Default:
+# pipeline_prefetch off
+
+# TAG: high_response_time_warning (msec)
+# If the one-minute median response time exceeds this value,
+# Squid prints a WARNING with debug level 0 to get the
+# administrators attention. The value is in milliseconds.
+#Default:
+# high_response_time_warning 0
+
+# TAG: high_page_fault_warning
+# If the one-minute average page fault rate exceeds this
+# value, Squid prints a WARNING with debug level 0 to get
+# the administrators attention. The value is in page faults
+# per second.
+#Default:
+# high_page_fault_warning 0
+
+# TAG: high_memory_warning
+# If the memory usage (as determined by mallinfo) exceeds
+# this amount, Squid prints a WARNING with debug level 0 to get
+# the administrators attention.
+#Default:
+# high_memory_warning 0 KB
+
+# TAG: sleep_after_fork (microseconds)
+# When this is set to a non-zero value, the main Squid process
+# sleeps the specified number of microseconds after a fork()
+# system call. This sleep may help the situation where your
+# system reports fork() failures due to lack of (virtual)
+# memory. Note, however, if you have a lot of child
+# processes, these sleep delays will add up and your
+# Squid will not service requests for some amount of time
+# until all the child processes have been started.
+# On Windows value less then 1000 (1 milliseconds) are
+# rounded to 1000.
+#Default:
+# sleep_after_fork 0
+
+# TAG: windows_ipaddrchangemonitor on|off
+# On Windows Squid by default will monitor IP address changes and will
+# reconfigure itself after any detected event. This is very useful for
+# proxies connected to internet with dial-up interfaces.
+# In some cases (a Proxy server acting as VPN gateway is one) it could be
+# desiderable to disable this behaviour setting this to 'off'.
+# Note: after changing this, Squid service must be restarted.
+#Default:
+# windows_ipaddrchangemonitor on
+
+# TAG: max_filedescriptors
+# The maximum number of filedescriptors supported.
+#
+# The default "0" means Squid inherits the current ulimit setting.
+#
+# Note: Changing this requires a restart of Squid. Also
+# not all comm loops supports large values.
+#Default:
+# max_filedescriptors 0
