Hi, All our clients are Proxy clients. We have rules that deny access to certain sites. Now, when one of the users tries to connect to one of the domains that are blocked, he gets a popup window, asking him for user authentication. After entering the information, he get's an HTTP 407 error. How can I prevent this ? , I just want that the user gets the HTTP 502, access denied page. > Danny > > View our available profiles on http://competences.CentricKsi.be ------------------------------------------------------------------------ LEGAL DISCLAIMER: The information included in this message is personal and/or confidential and intended exclusively for the addressees as stated.
