Thanks! Now I understand and will carefully check what's wrong and then update it... Yea I find when I paste the cache.log, I accidentally comment out the 'http_access deny all' when I run the code.. Lastly an interesting question is, '204.188.217.14 test' is actually my first line in userIp.conf Here is what in my userIp.conf: 204.188.217.14 test 204.188.217.18 wuhuarou <http://squid-web-proxy-cache.1019090.n4.nabble.com/file/t377697/1.png> So I am pretty confused about this error (also seems to be the key problem of my code) -- Sent from: http://squid-web-proxy-cache.1019090.n4.nabble.com/Squid-Users-f1019091.html _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
