Hello, For the setup I'm about to discuss, I used to use varnish, but due to stability issues decided to use squid instead. It's a rather usual reverse-proxy setup with squid 3.0. However, I do have one issue that could have been solved easily with varnish, but I can't find a good solution for squid. Thing is: Pages are cached. I want them to be cached, but.. there are some users that come with a Cookie NOCACHE. I want those users to get fresh pages, but at the same time, I want that other users would gather the cached pages as usually. I tried the following: acl nocache_cookie req_header Cookie NOCACHE cache deny nocache_cookie However, as described in http://www.squid-cache.org/Versions/v3/3.0/cfgman/cache.html - "use this to force certain objects to never be cached" and not only it does not cache then - but also updates it's cache lists that the object is not cached. So what I get is: #1 user comes w/o NOCACHE -- she gets a CACHE_MISS, page from originserver, and gets it cached #2 user comes w/o NOCACHE -- she gets a CACHE_HIT i.e. the cached page #3 user comes w/ NOCACHE -- she gets a CACHE_MISS and fresh page directly from originserver (page does not get cached) #4 user comes w/o NOCACHE -- she gets a CACHE_MISS, page from originserver, and gets it cached and obviously this is not what I want - I'd rather have page kept in cache at step #3 (at the same time feeding the page directly from originserver to user #3). In varnish I could have achieved that with sub vcl_recv { if (req.http.Cookie ~ "NOCACHE") { pass; } } Appreciate your thoughts! // Aurimas
