Yes, I've read the mail but I think that it is better to post it here... ;-) The main problem is that if I rewrite the $url (localhost [::1], or [5001::52] [3001::52] that are the addresses of the interfaces) it doesn't work. If I rewrite $url with "302:" code in front it works... but the behavior of the system is completely different. Replying to your requests, I'm working on 4 virtual machine called origin, core, mobile1, mobile2. In the origin and mobile I have apache servers running... those are my caches!!! When I write localhost, I want to redirect to the apache link example: I receive GET for http://[6001::101]/Big/big1.avi and I want to rewrite it like http://[5001::52]/Big/big1.avi, that is the link to the apache in the same machine where Squid is installed. This is not working. But if I redirect to another machine http://[4001::52]/Big/big1.aviwith apache it works.
