How we can say squid don't log this specific log ? Actually i am using grep -v 'Closing client connection due to lifetime timeout' /var/log/squid3/cache.log but it does not work for this kind of log because it logs in 2 line and second line is http://nameofwebsite.com/... and grep -v 'http://' may also hide useful logs . -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/question-in-WARNING-Closing-client-x-x-78-133-connection-due-to-lifetime-timeout-tp4661780p4662701.html Sent from the Squid - Users mailing list archive at Nabble.com.
