Gets the message returned to the server in response to an authentication challenge.
Assembly: System (in System.dll)
The property contains the authorization string that the client will return to the server when accessing protected resources. The actual contents of the message are defined by the authentication type the client and server are using. Basic HTTP authentication, for example, uses a different message than Kerberos authentication.
When an authentication module supports preauthentication, the property is sent with the initial request.
