I did that and get the following output: 200 OK Content-Length: 932 Content-Type: text/html Last-Modified: Thu, 02 Aug 2007 11:53:12 GMT Client-Date: Tue, 16 Oct 2007 09:36:16 GMT 200 OK Connection: close Date: Mon, 15 Oct 2007 23:40:02 GMT Server: Apache-Coyote/1.1 Content-Length: 855 Content-Type: text/html Client-Date: Tue, 16 Oct 2007 09:36:17 GMT Client-Peer: 205.234.170.164:80 Client-Response-Num: 1 So, how does that helps me or what does it say about caching behaviour of squid? Or in other words: How do I now manage it, that e.g. a html file will be held in cache/considered as fresh for let's say 30 min? Thanks again, Micha
