// The PreAuthenticate method specifies whether the authentication implemented
// by this class allows pre-authentication.
// Even if you do not use it, this method must be implemented to obey to the rules
// of interface implementation.
// In this case it always returns null.
public Authorization PreAuthenticate(WebRequest request, ICredentials credentials)
{
  return null;
}

' The PreAuthenticate method specifies whether the authentication implemented 
' by this class allows pre-authentication. 
' Even if you do not use it, this method must be implemented to obey to the rules 
' of interface implementation.
' In this case it always returns null. 
Public Function PreAuthenticate(ByVal request As WebRequest, ByVal credentials As ICredentials) As Authorization _
    Implements IAuthenticationModule.PreAuthenticate

  Return Nothing
End Function 'PreAuthenticate
