Defines the credential policy to be used for resource requests that are made using WebRequest and its derived classes.

|ShouldSendCredential(Uri, WebRequest, NetworkCredential, IAuthenticationModule)|
The credential policy determines whether to send credentials when sending a WebRequest for a network resource, such as the content of a Web page. If credentials are sent, servers that require client authentication can attempt to authenticate the client when the request is received instead of sending a response that indicates that the client's credentials are required. While this saves a round trip to the server, this performance gain must be balanced against the security risk inherent in sending credentials across the network. When the destination server does not require client authentication, it is best not to send credentials.
Use the AuthenticationManager.CredentialPolicy property to set an policy. The IAuthenticationModule that handles authentication for the request will invoke the ShouldSendCredential method before performing the authentication. If the method returns false, authentication is not performed.
