Hey guys, I've got a proprietary web application what we use as a back end for other applications, and I want to do some agressive caching using squid, as a test, to reduce the load on the back end. I spent 2-3 days on googling and reading the archives, but nothing I do or try seems to help! :( Here's the original back-end request (for one image in that app): ------------------------------------ [angelo@zvr-web-04 ~]$ wget -S --spider http://10.94.206.34:8000/stats_components/collapseon.gif --00:19:07-- http://10.94.206.34:8000/stats_components/collapseon.gif => `collapseon.gif' Connecting to 10.94.206.34:8000... connected. HTTP request sent, awaiting response... HTTP/1.0 200 OK Content-Type: image/gif Content-Length: 64 Length: 64 [image/gif] 200 OK ------------------------------------ As you can see, it's missing all cache headers, and expires and last-modified header. This is how my squid config is (now running on 2.6STABLE16, tried on 3.0RC1 too): ------------------------------------ hierarchy_stoplist cgi-bin acl QUERY urlpath_regex cgi-bin shutdown_lifetime 1 second acl all src 0.0.0.0/0.0.0.0 cache allow all #400GB disk cache cache_dir ufs /usr/local/squid/cache 409600 16 256 maximum_object_size 5 MB cache_mem 1024 MB cache_swap_low 90 cache_swap_high 95 maximum_object_size_in_memory 512 KB cache_replacement_policy heap LFUDA memory_replacement_policy heap LFUDA http_port 8000 vhost vport cache_peer 10.94.206.34 parent 8000 0 no-query originserver http_access allow all minimum_expiry_time 3600 seconds refresh_pattern . 3600 100% 3600 ignore-no-cache ignore-reload override-expire override-lastmod access_log /var/log/squid/access.log squid cache_log /var/log/squid/cache.log cache_store_log /var/log/squid/store.log strip_query_terms off ------------------------------------ This was the most agressive config I could found, and I expect the refresh_pattern line to force squid to cache.. But all my access.log file keeps saying is: ------------------------------------ 1215555215.645 1 127.0.0.1 TCP_MISS/200 200 HEAD http://localhost:8000/stats_components/collapseon.gif - FIRST_UP_PARENT/10.94.206.34 image/gif 1215555217.096 92 127.0.0.1 TCP_MISS/200 200 HEAD http://localhost:8000/stats_components/collapseon.gif - FIRST_UP_PARENT/10.94.206.34 image/gif 1215555217.940 1 127.0.0.1 TCP_MISS/200 200 HEAD http://localhost:8000/stats_components/collapseon.gif - FIRST_UP_PARENT/10.94.206.34 image/gif 1215555218.718 2 127.0.0.1 TCP_MISS/200 200 HEAD http://localhost:8000/stats_components/collapseon.gif - FIRST_UP_PARENT/10.94.206.34 image/gif ------------------------------------ And in the store.log: ------------------------------------ 1215555215.645 RELEASE -1 FFFFFFFF 98DDCD4857BAF3122EE99EB25E4C3800 200 -1 -1 -1 image/gif 64/0 HEAD http://localhost:8000/stats_components/collapseon.gif 1215555217.096 RELEASE -1 FFFFFFFF A3AE2ED993B031DBD93CF74E2BD64BC5 200 -1 -1 -1 image/gif 64/0 HEAD http://localhost:8000/stats_components/collapseon.gif 1215555217.940 RELEASE -1 FFFFFFFF FFFE8387EBAB471EC045EFA51F9AE472 200 -1 -1 -1 image/gif 64/0 HEAD http://localhost:8000/stats_components/collapseon.gif 1215555218.718 RELEASE -1 FFFFFFFF EA490C98564ABDF390D216E2C3DC210E 200 -1 -1 -1 image/gif 64/0 HEAD http://localhost:8000/stats_components/collapseon.gif ------------------------------------ Does anyone ave any idea's on why Squid won't cache the requests? -- Met vriendelijke groet, Angelo Hongens The Netherlands
