Re: [squid-users] Cache Chrome updates

Hey,

It might be not understood but StoreID in squid 3.4.4 might help with that.
I noticed that you are using SLES which I do not have a build node for yet.
Since there are dynamic variables in the url it is hard to cache it.
Note that there are other options in the request and response that can
cause the object to be un-cachable.

I can think about a pattern for StoreID to be used.
^http:\/\/[\d\w\-]+\.c\.pack\.google\.com\/([\S]+)\?
http://google_packs.squid.internal/$1

Which should work for many cases even with no strict refresh_pattern.
One of the issues is that you will need to fetch the full object when a
206 request is being pulled throw squid.
