Thanx for clarification. Then to this one, pls: Trying squid 3.4.3, I get squidclient -p nnn -U ????? -W ??????? mgr:pconn HTTP/1.1 200 OK Mime-Version: 1.0 Date: Fri, 07 Mar 2014 15:15:01 GMT Content-Type: text/plain Expires: Fri, 07 Mar 2014 15:15:01 GMT Last-Modified: Fri, 07 Mar 2014 15:15:01 GMT Connection: close Pool 0 Stats server-side persistent connection counts: req/ conn count ---- --------- 1 43 2 5 4 3 5 1 6 2 7 5 8 2 9 2 10 1 11 2 12 1 13 2 14 2 15 1 17 1 19 1 25 1 26 1 27 1 34 1 36 1 41 1 60 1 70 1 110 1 Pool 0 Hash Table item 0: 127.0.0.1:8887 item 1: 127.0.0.1:8887 ------------------------------------------------------------------------------------- Does that mean, absolutely no persistent conn/pipelining to the client (FF, pipelining enabled; Chrome) ? from squid.conf: pipeline_prefetch 3 client_persistent_connections on http_port nnn tcpkeepalive=3,3,125 BUT: With almost same squid.conf (besides pipeline_prefetch=on) for my squid2.7 squidclient -p nnn -U ????? -W ??????? mgr:pconn always shows me quite a few client side persistent conns with request counts up to about 50. So either I am missing something in squid.conf, upgraded from 2.7 -> 3.4.3, a bug in squidclient or a bug/change in behaviour between 2.7/3.4.3 ? (Note: Using 3.4.3, I can always see "Connection: keep-alive" in the response header. ) -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/HTTP-1-1-pipelining-tp4658574p4665110.html Sent from the Squid - Users mailing list archive at Nabble.com.
