I use the squid 2.6 server as the acceleartion mode. and override the default setting to eanble the caching of dynamic url (those contains ?) like http://www.example.com?a=123 I can see those content are cached via the accesslog, which says MEM_HIT. after I try to purge those content squidclient -m PURGE http://www.example.com?a=123 it always return 404, not found those url without ? works fine, which returns 200 and confirm the purge is successful. Is there any hints to purge those dynamic content( url has question mark , but cachable) appreciated! -- View this message in context: http://old.nabble.com/Purge-of-those-dynamic-url-return-404-tp26166699p26166699.html Sent from the Squid - Users mailing list archive at Nabble.com.
