Hi, Squid version: 2.5 Stable 5. O/S: Red Hat Enterprise Linux AS release 3 (Taroon) I'm struggling to find a method to run a local benchmark of Squid using Apache Benchmark without getting forwarding errors, I think it's because the test is local, it detects it's own hostname in the Via header. The reason I wanting to test locally is to discover results when bypassing limitations of 100MB Ethernet. I have tried to forge the 'Via' header, but it doesn't appear to make any differences. The test I'm running locally is . ./ab -v 5 -H "Via: notme.domain.net" -c 1 -t 120 http://www.realdomain.net/images/image.gif ab = Apache Benchmark. -v = Verbose lvl 5 -H Header -c = Number of multiple requests to make -t = Amount of time to run test Anyone had any success in running local benchmark against Squid I would love to hear.
