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.
