Interessante - Proxy Bypass websites

If your filter system filters based on words in the urls, and the kids are just using it to go to bebo or myspace, I've found that a lot of the proxies are based on the same scripts and the url's they produce have the same code after the proxy domain so you can just filter this based on the sites you want to filter.

That probably made no sense so an example...



both take you to bebo.com

So instead of filtering the domain, filter the "aHR0cDovL3d3dy5iZWJvLmNvbQ" part and you'll filter all the proxies that use this particular php.

No good if kids are accessing all sorts of sites, but we had a problem purely with bebo (they seem to have shunned myspace here). They didn't seem to understand they could go anywhere on the net through the proxies!
