Wow, i couldn't think about that. google might need tracking data that could be the reason they have blindly put vary * header. oh Irony, company which talks to all of us on how to deliver content is trying to do such thing.
I have looked at your patch but how do i enable that ? do i need to write custom ACL ? i know i need to compile and reinstall after applying patch but what do i need to do exactly in squid.conf file as looking at your patch i am guessing i need to write archive acl or i am too naive to understand C code :)
Also
reply_header_replace is any good for this ?

Some things G does only make sense whan you ignore all the PR about
wanting to make the web more efficient and consider it's a company whose
income is derived by recording data about peoples habits and activities.
Caching can hide that info from them.

Google are explicitly saying the response changes. I suspect there is
something involving Google account data being embeded in some of the
downloads. For tracking, etc.
If you are wanting to test it I have added a patch to
<http://bugs.squid-cache.org/show_bug.cgi?id=4604 > that should implement
archival of responses where the ACLs match. It is completely untested by
me beyond building, so YMMV.
