Re: [squid-users] Port # gets appended to Host header- patch (Re: q about redirect_rewrites_host_header)

Your concerns are valid I think, and stems from the fact that the
current httpd_accel_* directives are too primitive to accurately
represent the needs when building reverse proxies / "accelerators".

To address this and many other related issues there is a (completed)
task for reverse-proxy enhancements in Squid. See
http://squid.sourceforge.net/rproxy/. The goal is to have this included
in Squid-2.6.
