Otherwise as others have said this is fine. The default . and cgi-bin refresh_patterns supplied by Squid MUST be last on the list. Also note the updated syntax of the cgi pattern to prevent early discarding of mis-matched URL: > refresh_pattern -i \.index.(html|htm)$ 0 40% 10080 > refresh_pattern -i \.(html|htm|css|js)$ 1440 40% 40320 > refresh_pattern ^ftp: 1440 20% 10080 > refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 > refresh_pattern . 0 40% 40320 Amos
