Today we had computer science at school and my friend showed me a way to bypass the school website filter …
Since we got this filter, pupil’s can’t visit facebook and all the other social networking sites.

The special at our schoolnetwork is:
Every connection goes through our own schoolproxy, if we want to use other browsers like portable firefox, we have to configure this at the connection settings.

So he showed me this url: http://www.docoja.com/blue , it’s one of the few webproxy’s that havn’t blacklistet yet, and the sourcecode of this script is open source, you can download it here: http://www.glype.com .

So if you got problem’s with your school website filter, too, you can set up your own glype proxy site at a free webhost and use it (requires a webhost with installed php 5+ and curl).
