RegEx can, and do, change with each application, however, most try to be like Perl or C RegEx. "UNIX" RegEx also depends on the shell and program, like grep, that you are using. So, to shorten your answer, you will need to learn the Squid RegEx, and that may even vary in the what you are trying to do with squid. I have something a line like this for catching Windoze file extentions: acl WinExecs url_regex -i \.exe \.bat \.dll \.zip \.gz \.scr \.rar \.wmv \.mov http_access deny WinExecs It works pretty well. I put the \. in there so it doesn't trigger on something like executive.html but would still trigger on blah.executive.html *shrug* can't protect them all from teh entire world I guess. Maybe \.rar$ would be a better RegEx, but then what if the URL ends like .rar?blah=blah... I'm not going to test it for you, you can do that. Maybe that is what you are looking for? -- Scott - : send the line "unsubscribe linux-admin" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
