Proxy Port detection

Hi, In our enterprise we have URL filtering capabilities and we restrict the usual sites (Porn, Sports, Gambling etc..) We do not use a proxy, so everyone goes directly to the internet. I believe that some users put in their proxy settings an anonymous proxy using port 80 (which is obviously allowed) and in that manner avoid the restriction of the URL filtering. First thoughts: - Blocking all the anonymous proxy is imposible and would be a full time job - The use of a proxy is not an option right now Is there any way to detect this type of traffic (HTTP-Proxy) ? I'm sure someone had this problem before... Any help would be appreciated. Thanks __________________________________ Do you Yahoo!? Yahoo!
