What is the exact URL you tested with? Exactly what is CP configured to do with the request? The error is very clear: "The Uniform Resource Locator (URL) does not use a recognized protocol."

I don't know if you familiar with the HTTP Mapping feather in CP but this allow me to redirect http traffic from one source to another destination and play with the source and the destination ports, when I am doing so I can see the packets come into the ISA Proxy server but I am getting this error at the browser client. Technical Information (for support personnel) * Error Code: 502 Proxy Error. The Uniform Resource Locator (URL) does not use a recognized protocol. Either the protocol is not supported or the request was not typed correctly. Confirm that a valid protocol is in use (for example, HTTP for a Web request). (12006) Any clue ?
