Ok, I tried it out but it doesn't have the effect I want. :-( Here is what I am doing: I go to www.foo.de/pharma.html (squid is the accel for www.foo.de) and the access_log of foo.de shows this: IP.of.my.Squid - - [17/Oct/2007:14:55:57 +0200] "GET /pharma.html HTTP/1.0" 200 200 "-" "Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7" IP.of.my.Squid - - [17/Oct/2007:14:55:57 +0200] "GET /bild.jpg HTTP/1.0" 200 10107 "http://www.foo.de/pharma.html"; "Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7" IP.of.my.Squid - - [17/Oct/2007:14:55:58 +0200] "GET /favicon.ico HTTP/1.0" 404 301 "-" "Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7" I get the 200 code, which is fine. (BTW: Why does this request of favicon,ico appear? Is this an apache configuration thing?) Now, if I hit "F5" in Browser (with and without deleting the _browser_ cache) the access log shows this: IP.of.my.Squid - - [17/Oct/2007:14:59:26 +0200] "GET /pharma.html HTTP/1.0" 304 - "-" "Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7" IP.of.my.Squid - - [17/Oct/2007:14:59:27 +0200] "GET /bild.jpg HTTP/1.0" 304 - "http://www.foo.de/pharma.html"; "Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7" I get the 304 code (which is correct), but I don't want to have this control request. E.g. I want to say that squid "isn't allowed" to look at origin server for 30 min. Squid should consider the file(s) as fresh for 30 min and _after_ this period it should look after the file on origin server. I hope, it is clear what I mean and want. :-) But how do I achieve that? :-) As mentioned before, the cache_peer statement you wrote didn't work for that. Thanks a lot, Micha
