Hi Amos, Thank you for your help. Meanwhile i did some more testing and found something strange. The test system cannot resolve any internet domains itself so its nameserver uses a forwarder. If i silently drop the DNS request packets through the packet filter, everything works fine. There is no delay on any requests. But, if i just remove the forwarder in DNS, so that every request for external domains result in a NXDOMAIN DNS reply, a request takes about 90 seconds until it's finally processed. The point i don't understand is, why Squid forwards the request without any DNS reply but seems to do some timeout handling if NXDOMAIN is replied? I also checked if there is any communcation between local squid and the parent proxy but there isn't any in the latter test case. Greetings, Matthias
