I've done this by commenting following lines : #acl QUERY urlpath_regex cgi-bin \? #no_cache deny QUERY This way, URL with GET parameters does not have rule to not to cache these pages. And by updating the line starting with " refresh_pattern . " : refresh_pattern . 500000 100% 500000 override-expire override-lastmod reload-into-ims ignore-reload This seems to solve the most important cases. Nonetheless, this does not cache pages which answers by 301 or 302 (others?) HTTP response code. Any idea ? I am not sure about the percent usage. The doc says (http://www.squid-cache.org/Doc/config/refresh_pattern/) : 'Percent' is a percentage of the objects age (time since last modification age) an object without explicit expiry time will be considered fresh. I cannot really understand what is the formula here. Can anybody explain me please ? Thanks in advance PS : the more time I spend on Squid, the more I really appreciate this tool :-D -- View this message in context: http://www.nabble.com/Systematic-caching-tp25138412p25167494.html Sent from the Squid - Users mailing list archive at Nabble.com.
