The problem is that some webservers are configured so that
www1.wowhead.com and www1.wowhead.com:80 are different virtual hosts.
As you can see if you test with both of the hostnames I just provided,
www1.wowhead.com returns a 200 code.  Where as www1.wowhead.com:80
does a 302 redirect to www.wowhead.com instead of giving you a 200

By default, the plugin automatically adds the header:

Host: www1.wowhead.com:80

Ideally it would be nice to be able to provide a flag to not include
the port number in the host.
