WPAD is automatic discovery of the proxy (or to be exact automatic discovery of the PAC file telling the browser how it should use proxies). As the browser knows it's using a proxy and no RFCs violated there is no problem with proxy authentication. > Sorry I'm not clear.

Basic proxy authentication is performed per proxy host name, and as a result PAC based solutions may result in multiple authentication prompts during the browsing session, one per proxy used. The load balancer solution where the browser always goes to the same load balanced proxy address avoid this. Regards Henrik
