    public abstract class Authenticator

    Authenticator represents an implementation of an HTTP authentication mechanism. Sub-classes provide implementations of specific mechanisms such as Digest or Basic auth.

        Failure means the authentication has completed, but has failed due to invalid credentials.

        Sucess means that the authentication has succeeded, and a Principal object representing the user can be retrieved by calling Sucess.getPrincipal() .

        Retry means that another HTTP exchange is required. Any response headers needing to be sent back to the client are set in the given HttpExchange. The response code to be returned must be provided in the Retry object. Retry may occur multiple times.
