If you have one of the BSD systems make that diskd. Those storage types are faster on their OS that plain ufs. Better handling for large caches too. > redirect_rewrites_host_header off > cache_replacement_policy lru I'd think "heap lru" might be better. Up to you though. > acl QUERY urlpath_regex cgi-bin \?

The CONNECT rule does need to be "deny CONNECT !SSL_Ports". With SSL_Ports defining what HTTPS ports are safe to use. CONNECT can be very unsafe when email etc ports are allowed since it opens an anonymous random destination tunnel with no checking on what gets passed through. > http_access deny all > icp_access allow our_networks > icp_access allow localhost > icp_access deny all > refresh_pattern \.jpg$ 3600 50% 60 ignore-reload > refresh_pattern \.gif$ 3600 50% 60 ignore-reload > refresh_pattern \.css$ 3600 50% 60 ignore-reload > refresh_pattern \.js$ 3600 50% 60 ignore-reload > refresh_pattern ^ftp: 1440 20% 10080 > refresh_pattern ^gopher: 1440 0% 1440 > refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 > refresh_pattern \.html$ 300 50% 10 ignore-reload I'd shift that one http pattern above up above the ftp pattern. Do add back the default . (dot) rule: refresh_pattern . 0 20% 4320 Amos
