Hi Rehan, Let's keep this on the list. The key is site and content rules. You must force your clients to be Web Proxy clients, since only Web Proxy clients support content control. HTTP uses MIME type and HTTP tunneled FTP users file extension. The challange is that the server admin can set any MIME type they want and if users are using warez proxy servers on their own machines that tunnel through your port 80 to access other protocols, you're sunk, even worse if they're tunneling through 443, in which case you need to block the servers they're connecting to. Bottom line.. there is no easy solution.
