Hello, 1.This is the refresh_pattern part of my squid.conf: refresh_pattern . 0 20% 4320 refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i \.gif$ 14400 80% 43200 ignore-reload When sending the client request header - Cache-Control: no-cache for a .gif file, I still get 'miss' from the squid. Am I doing something wrong here? 2. I would like to configure squid to ignore querystring parameters when deciding to refresh a object of a certain type (e.g .swf files). for example : if somefile.swf?x=1 is found in the cache, the request for somefile.swf?x=2 would return the same cached object Is this configuration possible via refresh patterns or some other way?
