Re: Block Proxies - Website
One way, I guess, is attempt to connect to the IP of the visitor on port 80, 8080, or other common proxy server ports. Not 100% reliable, maybe kinda slow too.
Another way is to create a database of proxy servers (from public proxy server lists) and have it extract those proxy servers from the web address and keep the database updated. Then check if the IP/DNS name of the visitor is found in that list.
Those are the only 2 ways I can think of other than your idea.
