squid 2.7 cannot handle HTTP/1.1 which is needed for, among other things, the chunk encoding (compression) one. You'll simply not be able to get it working with squid 2.7.
i know squid 3.1 has made great improvements on HTTP/1.1 support, but as i dont use it, i cannot guarantee you what's working and what's not.
check squid 3.1 changelogs looking for HTTP/1.1 related things. Also i'd suggest you to search this mailing list archives, as HTTP/1.1 support on squid was vastly discused here by other users.

Hello everyone, I have a small problem with squid (Squid 2.7.STABLE9). I'm trying to optimize our IIS6 web portal. I activated HTTP compression both for static and dynamic content, and this works OK when the browser asks for content directly to the IIS server ... BUT, when the browser asks for content thru Squid. Content is effectively served by IIS but as the Content-Encoding header is missing, so nor IE or FireFox can handle it !
