Hi List; It's really surprising for me that my proxy has been bypassed by on of the user using the "proxybuilder" proxy. what it's doing is that that particular php based proxy rewrite the mimetype. and that request going through my actual proxy server, but as that script is rewriting the mime type and it's encrypting as test/html. Overall whatever the mime type based ACL i have in my server it's ignoring them. and that person has the access of those blocked urls . has anyone faced this kind of situation........ /\ Tarak From Chandigarh to Chennai - find friends all over India.
