Hello everyone, (sorry if this email is duplicate because I sent this by Outlook before but received no comments about this problem). I’m using these configurations which work fine with squid 3.1 every items gets HIT. However these configurations don’t work properly with Squid 3.2 and 3.3, because I always get MISS with all items http_port 127.0.0.1:82 accel ignore-cc cache_peer 192.168.2.43 parent 80 0 no-query originserver name=Site1 max-conn=15 cache_peer_domain Site1 mysite.com refresh_pattern -i ((.)*) 30 30% 60 ignore-no-cache ignore-private ignore-reload ignore-no-store override-lastmod override-expire Header from 3.3 version: HTTP/1.1 200 OK Cache-Control: private Content-Length: 117991 Content-Type: text/html; charset=utf-8 Expires: Thu, 21 Nov 2013 03:12:14 GMT Server: Microsoft-IIS/7.5 Date: Thu, 21 Nov 2013 03:12:15 GMT X-Cache: MISS from localhost.localdomain Connection: close Please help. -- Best Regards, Kiên Lê
