+     *  or an error is returned.
+     *
+     *  If the request requires authentication and the Authorization header 
+     *  in the request is missing or not acceptable, then this method should 
+     *  set the WWW-Authenticate header in the response object, set the status 
+     *  in the response object to Unauthorized(401) and return false. 
+     *  See also RFC 2617: HTTP Authentication: Basic and Digest Access Authentication 
+     *  (available at http://www.ietf.org/rfc/rfc2617.txt).

+     *  If the request requires a secure connection and the getScheme method 
+     *  in the request does not return 'https' or some other acceptable secure protocol, 
+     *  then this method should set the status in the response object to Forbidden(403) 
+     *  and return false.
+     *  
+     *  When this method returns false, the Http Service will send the response back to 
+     *  the client, thereby completing the request. When this method returns true, the 
+     *  Http Service will proceed with servicing the request.
+     *  
+     *  If the specified request has been authenticated, this method must set the 
+     *  AUTHENTICATION_TYPE request attribute to the type of authentication used, 
+     *  and the REMOTE_USER request attribute to the remote user 
+     *  (request attributes are set using the setAttribute method on the request). 
+     *  If this method does not perform any authentication, it must not set these attributes.
