改为（定义内部DNS或hosts文件 或根据具体情况定义acl 设置转发）
acl ipcndm   dstdomain  .ipcn.org
cache_peer www.ipcn.org parent 80 0 no-query no-digest no-netdb-exchange login=PASS originserver
cache_peer_access www.ipcn.org allow ipcndm
cache_peer_access www.ipcn.org deny all

always_direct allow !ipcndm
never_direct allow ipcndm

其他还有很多
比如：不记图片类访问日志
acl nolog urlpath_regex \.gif \.jpg \.css \.js \.swf
access_log /data/squid/var/logs/access.log common !nolog

1.    http_port加参数
a)    http_port 80 vhost
2.    cache_peer hostname type http_port icp_port [options]
