Hello, at the beginning I would like to mention that I've already search for the answer to my question, found similar topics, but none of them helped me to completely solve my problem.
The thing is I have monitoring server with cgi scripted site on it. The site fetches various data and generates charts 'on-the-fly'. Now it is only available via HTTPS with htaccess-type authorization. The bad thing is that it is quite often browsed and everytime it gets HTTP requests, it has to generate all of the charts (quite a lot of them) on the fly, which not only makes loading the page slow, but also affects server's performance. There 4 most important things about the site: * index.cgi - checks current timestamps and generates proper GET requests to generate images via gen.cgi * gen.cgi - it receives paramers via GET from index.cgi and draws charts * images ARE NOT files placed on server, but form of gen.cgi links (e.g. "gen.cgi?icon,moni_sys_procs,1314022200,1,161.6,166.4,FFFFFF...") * images generation links contain most up-to-date timestamp for every certain image What I want to do is to set another server in the middle, which would run squid and act as a transparent, accelerating proxy. My main problem is that squid doesn't want to cache anything at all. My goal is to: * cache index.cgi for max 1 minute time - since it provides important data to generate charts * somehow cache images generated on the fly as long, as there aren't new one in index.cgi (only possible if timestamp has changed) To make it simpler to develop, I've temporary disabled authorization, so my config looks like: ################################################################# http_port 5080 accel defaultsite=xxxx.pl ignore-cc # HTTP peer cache_peer 11.11.11.11 parent 5080 0 no-query originserver name=xxxx.pl hierarchy_stoplist cgi-bin cgi ? refresh_pattern (\.cgi|\?) 0 0% 0 refresh_pattern . 0 20% 4320 acl our_sites dstdomain xxxx.pl http_access allow our_sites cache_peer_access xxxx.pl allow our_sites cache_peer_access xxxx.pl deny all ################################################################## Unfortunately, access.log looks in this way: 1314022248.996 66 127.0.0.1 TCP_MISS/200 432 GET http://xxxx.pl/gen.cgi? - FIRST_UP_PARENT/xxxx.pl image/png 1314022249.041 65 127.0.0.1 TCP_MISS/200 491 GET http://xxxx.pl/gen.cgi? - FIRST_UP_PARENT/xxxx.pl image/png 1314022249.057 65 127.0.0.1 TCP_MISS/200 406 GET http://xxxx.pl/gen.cgi? - FIRST_UP_PARENT/xxxx.pl image/png 1314022249.058 62 127.0.0.1 TCP_MISS/200 438 GET http://xxxx.pl/gen.cgi? - FIRST_UP_PARENT/xxxx.pl image/png 1314022249.062 68 127.0.0.1 TCP_MISS/200 458 GET http://xxxx.pl/gen.cgi? - FIRST_UP_PARENT/xxxx.pl image/png 1314022249.107 64 127.0.0.1 TCP_MISS/200 482 GET http://xxxx.pl/gen.cgi? - FIRST_UP_PARENT/xxxx.pl image/png 1314022249.126 66 127.0.0.1 TCP_MISS/200 460 GET http://xxxx.pl/gen.cgi? - FIRST_UP_PARENT/xxxx.pl image/png 1314022249.126 67 127.0.0.1 TCP_MISS/200 478 GET http://xxxx.pl/gen.cgi? - FIRST_UP_PARENT/xxxx.pl image/png 1314022249.127 63 127.0.0.1 TCP_MISS/200 467 GET http://xxxx.pl/gen.cgi? - FIRST_UP_PARENT/xxxx.pl image/png 1314022249.169 61 127.0.0.1 TCP_MISS/200 420 GET http://xxxx.pl/gen.cgi? - FIRST_UP_PARENT/xxxx.pl image/png 1314022249.191 63 127.0.0.1 TCP_MISS/200 524 GET http://xxxx.pl/gen.cgi? - FIRST_UP_PARENT/xxxx.pl image/png 1314022249.193 66 127.0.0.1 TCP_MISS/200 421 GET http://xxxx.pl/gen.cgi? - FIRST_UP_PARENT/xxxx.pl image/png 1314022249.197 69 127.0.0.1 TCP_MISS/200 530 GET http://xxxx.pl/gen.cgi? - FIRST_UP_PARENT/xxxx.pl image/png Could someone tell me how to configure squid to meet my expactations? I will be so much grateful for any help.
