Please upgrade. 2.6 is now unable to cope with many web applications
which are starting to assume or require HTTP/1.1 functionality.

I've found a similar problem in this post using mod_proxy (http://serverfault.com/questions/388927/apache-reverseproxypass-redrects-to-http-rather-than-https)

This is not clear what you are saying the problem is. With properly
configured Squid the proxy->server connection should be passing request
through exactly as the client delivered them so te server apps have full
and correct details to work from.

Are you able to share the squid.conf contents? that will help clarify
what the proxy is actually doing vs what you think it should be doing.
