This is sort of off-topic, but have you considered using a deb repo mirroring software?
(it would mean that you need to update your clients to point to that rather than google, but that's not really difficult).
software like aptly (aptly.info) are really good about this (though a little hard to get going in the first place). or a deb-caching proxy (apt-cacher-ng? squid-deb-proxy?)

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 :)Alsoreply_header_replace is any good for this ?On Tue, Oct 4, 2016 at 7:47 PM, Amos Jeffries <squid3@xxxxxxxxxxxxx> wrote:On 5/10/2016 2:34 a.m., Hardik Dangar wrote:

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.
