I want to use squid to cache all the resources needed by the linux application and only download again if they are modified. I have made the changes that you have indicated me. I am using firefox to make a test, because with the linux application I can't test at this moment. I put squid as the proxy, but always download the resource. I saw that the store.log file is updating with the asked resources. This is the file content: 1213266172.237 RELEASE 00 0000000F EAEEC8FE1A6E2D8434959FA6301A18A0 200 1213266 171 1194446956 -1 video/mpeg 6250477/386763 GET http://192.168.240.158:808 0/test/video.mpg 1213266174.770 RELEASE 00 00000010 197E8B6BA5687EDF00E293B32088D2E7 200 1213266 174 1194446956 -1 video/mpeg 6250477/251763 GET http://192.168.240.158:808 0/test/video.mpg I put maximum_object_size 300000 KB because the video.mpg is higher than 8 MB (10 MB exactly), but I tried to ask small resources (images) and the results are the same. I read squid configuration and for default squid allow all to be catched. What am I doing wrong? Thank you again for your help.

I need some help, please. I suspect you are trying to do some sort of web mashup involving Squid? I've found the best ways to do those is to have squid as the public domain gateway and do the app-linking/routing in the squid config.

I'd expect to see a control saying the intercepted network has access through. acl localnet src 192.168.0.0/16 http_access deny !localnet and drop the "deny all" down a bit.... > icp_access allow all allow all with no port configured? looks like you can kill this. > hierarchy_stoplist cgi-bin ? > access_log /var/log/squid/access.log squid > acl QUERY urlpath_regex cgi-bin \? > cache deny QUERY > refresh_pattern ^ftp: 1440 20% 10080 > refresh_pattern ^gopher: 1440 0% 1440 > refresh_pattern . 0 20% 4320 > acl apache rep_header Server ^Apache > broken_vary_encoding allow apache > coredump_dir /var/spool/squid > cache_dir ufs /var/spool/squid 700 32 512 > http_port 3128 transparent > icp_port 0 > cache_peer localhost.home.nl parent 8080 0 default > acl HOME dstdomain .home.nl > always_direct allow all > never_direct allow all Those lines contradict each other 'everything MUST go direct + nothing EVER allowed direct'. You want just: never_direct allow HOME never_direct deny all cache_peer_access localhost.home.nl allow HOME cache_peer_access localhost.home.nl deny all http_access allow HOME .. the deny I mentioned dropping down goes about here.

What about intercepting the requests clients make directly to your web app? Since the app knows its running on port 8080 it will tell the clients that in its URLs, and the 'clients' do not know about Squid they will not ask for those objects over port 80. > > > The cache.log content is this: > > 2008/06/11 11:30:52| Starting Squid Cache version 2.6.STABLE19 for > i386-redhat-linux-gnu... > 2008/06/11 11:30:52| Process ID 8617 > 2008/06/11 11:30:52| With 1024 file descriptors available > 2008/06/11 11:30:52| Using epoll for the IO loop > 2008/06/11 11:30:52| ipcacheAddEntryFromHosts: Bad IP address 'tele1' > 2008/06/11 11:30:52| ipcacheAddEntryFromHosts: Bad IP address 'svc1' Your hosts file has corrupt content. Apart from all that, squid looks to be running fine. Amos -- Please use Squid 2.7.STABLE1 or 3.0.STABLE6
