The AuthenticationService class provides script access to user authentication. It calls methods of the authentication service through the same infrastructure used to call any other Web service method.
The built-in authentication service is located on the server in a predefined location.
The AuthenticationService class is a singleton; it has only one instance with a global point of access. It is always available to your application and you do not have to instantiate it.
The following example shows how to use the AuthenticationService class to check whether a user is authenticated. For more information, see Using Forms Authentication with ASP.NET AJAX.
