A delegation application is one in which part of the Web server's work is delegated to a secondary server process running on a different computer. For example, a Web server that accesses a database server running on a different host computer is a delegation application.

If the user has logged on locally, as is the case with Basic Authentication, Microsoft® Windows NT® security permits those user credentials to be honored by a secondary server in a delegation application. If the user has logged on to the network using Windows NT Challenge/Response, those credentials are not honored. In this case, the delegation application can only run if the secondary server and Web server are running on the same host computer.
