CredentialCache
This class maintains credentials for
multiple network resources. If you
are developing a client application that needs to authenticate itself
to more than one server, you can store an instance of this class in
the WebRequest.Credentials property.
After you create an instance of this class, use the Add( ) method to associate NetworkCredential
objects with a URI and authentication type (using a string such as
"Basic" or "Digest“). Then you
can assign the CredentialCache instance to the
WebRequest.Credentials property to use the
credentials for future web requests.
