Greetings all, Im having problems with cache hit rates im trying to work out. I have a complete random URL im concentrating on: http://performanceforums.com/forums/mgc_cb_evo/clientscript/dojo/dijit/themes/claro/layout/TabContainer.css No matter what i do, i cannot get this URL to be served from the cache, it's always a MISS. Can anyone help me work out why? I've cut down the squid conf to its most simple required items, with a ridiculous single refresh_pattern: ------------------------------------------------------------- debug_options ALL,1 22,5 cache_access_log /var/log/squid3/access.log cache_log /var/log/squid3/cache.log cache_store_log /var/log/squid3/store.log cache_effective_user proxy cache_effective_group proxy http_port 3128 cache_replacement_policy heap LRU maximum_object_size 512 MB minimum_object_size 0 KB cache_dir aufs /data/02-1000-DATA/squid 128000 24 128 cache_mem 512 MB http_access allow all refresh_pattern . 43200 100% 43200 ignore-private ignore-no-cache ignore-must-revalidate ignore-reload override-expire override-lastmod store-stale ignore-auth ------------------------------------------------------------- Using this to request the URL from Squid: curl -x 192.168.1.1:3128 --silent -o /dev/null --dump-header /dev/stdout "http://performanceforums.com/forums/mgc_cb_evo/clientscript/dojo/dijit/themes/claro/layout/TabContainer.css"; Curl output: ---------------------------------------------- HTTP/1.1 200 OK Date: Wed, 12 Mar 2014 06:03:32 GMT Server: Apache/2.2.16 (Debian) Last-Modified: Tue, 10 Jul 2012 07:46:42 GMT ETag: "20e25cb-3674-4c474ee6b1c66" Accept-Ranges: bytes Content-Length: 13940 Vary: Accept-Encoding Access-Control-Allow-Origin: http://www.performanceforums.com Access-Control-Allow-Origin: http://performanceforums.com Content-Type: text/css X-Cache: MISS from linux X-Cache-Lookup: MISS from linux:3128 Via: 1.1 lserv (squid/3.3.8) Connection: keep-alive ---------------------------------------------- store.log (two requests): ---------------------------------------------- 1394604192.912 RELEASE -1 FFFFFFFF 2735246D8165FF6D0185A8FD58055B57 200 1394604192 -1 1394704192 x-squid-internal/vary -1/0 GET http://performanceforums.com/forums/mgc_cb_evo/clientscript/dojo/dijit/themes/claro/layout/TabContainer.css 1394604192.912 RELEASE 00 0000009D 5FEA97A372BAA3C8605EE7284843456E 200 1394603265 1341906402 -1 text/css 13940/13940 GET http://performanceforums.com/forums/mgc_cb_evo/clientscript/dojo/dijit/themes/claro/layout/TabContainer.css 1394604193.367 SWAPOUT 00 0000009D E2ED99F3F1DFBDA6B0B1F26468B81319 200 1394604192 1341906402 -1 text/css 13940/13940 GET http://performanceforums.com/forums/mgc_cb_evo/clientscript/dojo/dijit/themes/claro/layout/TabContainer.css 1394604212.993 RELEASE -1 FFFFFFFF 6748E1D3C84D15B2B11C0E0AF81F34EE 200 1394604212 -1 1394704212 x-squid-internal/vary -1/0 GET http://performanceforums.com/forums/mgc_cb_evo/clientscript/dojo/dijit/themes/claro/layout/TabContainer.css 1394604212.993 RELEASE 00 0000009D 29EB2C8048CE1402B6B4A6EE549FDD0A 200 1394604192 1341906402 -1 text/css 13940/13940 GET http://performanceforums.com/forums/mgc_cb_evo/clientscript/dojo/dijit/themes/claro/layout/TabContainer.css 1394604213.410 SWAPOUT 00 0000009D E2ED99F3F1DFBDA6B0B1F26468B81319 200 1394604212 1341906402 -1 text/css 13940/13940 GET http://performanceforums.com/forums/mgc_cb_evo/clientscript/dojo/dijit/themes/claro/layout/TabContainer.css ---------------------------------------------- cache.log: ---------------------------------------------- 2014/03/12 16:36:12.156 kid1| ctx: exit level 0 2014/03/12 16:36:12.156 kid1| refresh.cc(540) getMaxAge: getMaxAge: 'http://performanceforums.com/forums/mgc_cb_evo/clientscript/dojo/dijit/themes/claro/layout/TabContainer.css' 2014/03/12 16:36:12.367 kid1| ctx: enter level 0: 'http://performanceforums.com/forums/mgc_cb_evo/clientscript/dojo/dijit/themes/claro/layout/TabContainer.css' 2014/03/12 16:36:12.367 kid1| refresh.cc(247) refreshCheck: refreshCheck: 'http://performanceforums.com/forums/mgc_cb_evo/clientscript/dojo/dijit/themes/claro/layout/TabContainer.css' 2014/03/12 16:36:12.367 kid1| refresh.cc(262) refreshCheck: refreshCheck: Matched '. 2592000 100%% 2592000' 2014/03/12 16:36:12.367 kid1| refresh.cc(264) refreshCheck: age: 60 2014/03/12 16:36:12.367 kid1| refresh.cc(266) refreshCheck: check_time: Wed, 12 Mar 2014 06:07:12 GMT 2014/03/12 16:36:12.367 kid1| refresh.cc(268) refreshCheck: entry->timestamp: Wed, 12 Mar 2014 06:06:12 GMT 2014/03/12 16:36:12.367 kid1| refresh.cc(207) refreshStaleness: FRESH: age 60 <= stale_age 52697970 2014/03/12 16:36:12.367 kid1| refresh.cc(288) refreshCheck: Staleness = -1 2014/03/12 16:36:12.367 kid1| refresh.cc(373) refreshCheck: refreshCheck: object isn't stale.. 2014/03/12 16:36:12.367 kid1| refresh.cc(382) refreshCheck: refreshCheck: returning FRESH_LMFACTOR_RULE 2014/03/12 16:36:12.367 kid1| http.cc(495) cacheableReply: YES because HTTP status 200 ---------------------------------------------- Thanks in advance.
