Oops... I meant Vary: Accept-Encoding, Cookie E ----- Original Message ----- From: Elli Albek <elli@xxxxxxxxxxxxxxx> To: 'Amos Jeffries' <squid3@xxxxxxxxxxxxx> Cc: squid-users@xxxxxxxxxxxxxxx Sent: Sun, 18 Jan 2009 22:00:18 -0800 (PST) Subject: RE: Caching pages for users without a cookie (guest) You mean adding Set-Cookie to the vary header? Something like: Vary: Accept-Encoding Set-Cookie The reason is that since all the cookies are lumped into one request header, you have there analytics tracking cookies which are different for every browser client. So the cache key is going to be unique per client since the request cookies are unique per client. This is in addition to a few of our cookies that can create thousands of combinations. Good point about other proxies between squid and the client. I did not think about it. Maybe its best if squid does not pass on the validators to the client, so the next proxies just pass through. So the validators in that case are just for app server to squid communications. E
