Hi Squid Users. I'm looking to setup a reverse proxy cache with SQUID that image changes very often. For example,I want change cache-image immediately if original server's image modified. (eg. Internet shopping mall's images ) If it's impossible , it must change as soon as possible. I try to test follow config. --------------------------- refresh_pattern -i \.jpg$ 0 20% 300 refresh_pattern -i \.gif$ 0 20% 300 refresh_pattern -i \.swf$ 0 20% 300 --------------------------- Thank you very much for your help and advice.
