bypass proxy

At work (which is a school) many students are using a bypass proxy to get past blocked sites. New bypass proxy sites pop up every day and you cant aviod them.

Can anything be done?

 

This is a link to Microsoft help on proxy by-pass, I hope you can find a way to suit you through the links, as I have not dealt with this problem , myself.
- Students get more resourceful all the time, you are teaching them too well.
Good luck

well how can i unblock sites that i find out i need, without using a bypass proxy myself?

 

I am sorry, I am unable to advise, but someone else might come on and offer help on that

 

Have students report to teachers regarding that, so they can get back to you.

Then go into whatever filtering software you are using and add the exceptions.

 

you cannot block all the bypass proxies as they popup every day.

How does it work exactly . I know php myself so does it physcially change the headers on the webpages?

 

New bypass proxies pop up every day?

I think you are giving your students a little too much credit.
