Is there any way to block online web proxies and tunnling sites using TMG web proxy.
I have tride most of the things given in forum, technet and help. if i block a "technical information" catagory it blocks the online web proxy and tunnling sites but it also blocks all sites having technical informaion like dell, hp, MS, IBM and so
many.
I blocked the anonymizers it blocks some of the online proxy. https inspaction is not working.
