Hello, In older squid (before 3.0), the config directives for dynamic pages are: acl QUERY urlpath_regex cgi-bin \? cache deny QUERY In squid 3.0, the directives above were removed, and uses a refresh_pattern instead: refresh_pattern (cgi-bin|\?) 0 0% 0 What's the difference in effect between those two config? Thanks. -- Regards, Jeff. - Peng.Kyo@xxxxxxxxx
