Thanks for your input, but unfortunately it is still not working. each time I launch : [curl-machine]#curl http://omp.wc.be/home.html I get in store.log : 1192090981.782 RELEASE 00 00000018 CE042BF5E20CD75407DE72B1C8D0CA2C 200 1192093905 1192089432 -1 text/html 18/18 GET http://omp.wc.be/home.html 1192090981.782 SWAPOUT 00 00000019 EFE6712C44DC67B734C8EC1E9436327C 200 1192093910 1192089432 -1 text/html 18/18 GET http://omp.wc.be/home.html ... and I see on the http server ther reqest coming in, so squid is still not caching. I do not understand why squid RELEASES the object first and then does SWAPOUT to disk. Here you see the result of curl -I http://omp.wc.be/home.html (also same behaviour on squid machine, meaning squid machine still contacts http server.

Using following conf (using comments by Amos) ... #ACCELERATOR ################### http_port 80 accel defaultsite=omp.wc.be cache_peer 10.10.10.3 parent 80 0 no-query originserver name=webserver ######ACLS############### acl all src all cache_peer_domain webserver omp.wc.be acl mydomain dstdomain omp.wc.be http_access allow mydomain never_direct allow mydomain http_access deny all #CACHING RULES ############### acl QUERY urlpath_regex cgi-bin \? cache deny QUERY cache allow all refresh_pattern . 1440 20% 4320 #MISCELLANIOUS ##################3 visible_hostname omp.wc.be cache_effective_user squid #cache_effective_group squid dns_testnames omp.wc.be dns_nameservers 127.0.0.1 cache_mem 50 MB [root@rack4top etc]# ... I allready tried the following : 1. removeing the cache_dir (squid -k shutdown ; rm -fr /usr/local/squid/var/cache/* ; squid -z) and recreating it; start squid 2. added the dns_nameservers 127.0.0.1 statement, bcc otherwise I get warning at startup that there are no DNS servers specified in /etc/resolv.conf /etc/resolv.conf only contains "files" an I am using /etc/hosts for dns lookup on the squid machine. cat /etc/hosts looks like this : 127.0.0.1 rack4top localhost.localdomain localhost 13.1.1.1 omp.wc.be (13.1.1.1 is interface where curl-machine talks to.) 3. commented the "refresh_pattern . 1440 20% 4320" statement and restarted squid. same behaviour (so I uncommneted it now) note : I compild squid with only --snmp-enabled option. furthermore I did NOT specify any other options with configure. Can this be an issue ? What am I overlooking ?
