Hi Amos, I think this request time is the time needed to serve the entire request. How is icp_query_timeout related to that, it should be only about the query through ICP protocol? Otherwise we are using our own cache peer which is dealing with the youtube content, which supports ICP protocol, it's connected to squid as cache peer and the squid (based on ACL) is sending youtube requests to the cache peer. I'm comparing squid 3.1.9 and 3.3.8 and what I notice is that without changing any other element of the system with icp_query_timeout 9000 set for both test cases, with squid 3.1 I don't get any TIMEOUT_FIRSTUP_PARENT in the access.log, and with squid 3.3.8 I'm getting lot's of them and this is reducing our performance. Please suggest what can be the difference and what I can check further. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/icp-query-timeout-directive-is-not-working-in-3-3-8-for-some-reason-tp4661324p4661417.html Sent from the Squid - Users mailing list archive at Nabble.com.
