Hello Guys, I've created a Squid url_regex acl to block url's that contain the word xxx followed by a period(.), like in www.xxx.com for example. The issue is, there are some sites that have pdf's to download that contain XXX in the file name, like www.thepdfsite.com/xxx.pdf . Is there a way to create a reg. expression that catches all other (xxx.\.) but the ones with *.pdf extension ? I've been reading regex tutorials for 2 days, and I was able to create an expression using perl regex, [xxx(?!.*pdf.*)] , but it does not seem to work on squid, apparently different implementation. Thanks for any help provided, Rodrigo
