Thanks for your advice. I get this in access.log file. 192.168.12.35 - - [16/Jun/2005:12:49:18 +0900] "GET http://www.localhost.com HTTP/1.1" 503 2490 TCP_MISS:NONE In my hosts file, www.localhost.com is indicated to squid server but actual www.localhost.com server is 192.168.12.123. I can ping www.localhost.com from squid server, of course. When I installed squid I just did #./configure #make #make install to install it. Did I miss anything during instllation?
