Abstract: A method is presented for selecting an HTTP authentication scheme at a client computer. A request message is sent from the client computer to a server computer to access information on the server computer. In response, the client computer receives a response message from the server computer. The response message includes an HTTP header that includes a first scheme identifier, indicating a first HTTP authentication scheme and a second scheme identifier, indicating a second HTTP authentication scheme. If the client computer does not support the second HTTP authentication scheme, the client computer uses the first HTTP authentication scheme when sending another HTTP message to the server computer. If the client computer supports the second HTTP authentication scheme, the client computer uses the second HTTP authentication scheme when sending another HTTP message to the server computer.
