But "mgr:client_list" shows different type of info, as far as I can see. It shows current client connections, whereas "mgr:pconn" shows past connection statistics (effectiveness) My squid2.7: /usr/local/squid/etc# ../sbin/squid27 -v Squid Cache: Version 2.7.STABLE9-20110824 /usr/local/squid/etc# squidclient -p nnnn -h 127.0.0.1 -U manager -W ????? mgr:pconn HTTP/1.1 200 OK Date: Mon, 10 Mar 2014 08:06:33 GMT Content-Type: text/plain Expires: Mon, 10 Mar 2014 08:06:33 GMT Connection: close Client-side persistent connection counts: req/ conn count ---- --------- 0 15160 1 9681 2 2801 3 1547 ..... 203 2 208 1 216 1 220 1 231 1 250 1 Server-side persistent connection counts: req/ conn count ---- --------- 1 95899 2 2066 3 1049 83 1 99 1 104 1 110 1 112 1 132 1 So the first part of 2.7-pconn statistics is dropped on later squid-versions, although quite interesting, I think. May be, I should file a bug or feuture request ? -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/HTTP-1-1-pipelining-tp4658574p4665114.html Sent from the Squid - Users mailing list archive at Nabble.com.
