Bug#499547: "Expect: 100-continue" used in http request

Package: boinc-client
Version: 6.2.14-2
Severity: important

when using the squid proxy I get trouble when sending http requests from boinc-client:
19-Sep-2008 18:05:11 [---] [http_debug] [ID#0] Received header from server: HTTP/1.0 417 Expectation failed
19-Sep-2008 18:05:11 [---] [http_debug] [ID#0] Received header from server: Server: squid/2.7.STABLE3
The reason is the mentioned entry in the request:
19-Sep-2008 18:55:53 [---] [http_debug] [ID#0] Sent header to server: POST /cgi/cgi HTTP/1.1
User-Agent: BOINC client (i686-pc-linux-gnu 6.2.14)
Host: www.primegrid.com
Accept: */*
Accept-Encoding: deflate, gzip
Content-Type: application/x-www-form-urlencoded
Content-Length: 5661
Expect: 100-continue

I found in the boinc changelog (back in 2006):
    - suppress "Expect: 100 continue" in HTTP header.
        Apparently this causes problems with some proxies
