Examples of org.restlet.data.ChallengeRequest

org.restlet.data.ChallengeRequest
Authentication challenge sent by an origin server to a client. Upon reception of this request, the client should send a new request with the proper {@link ChallengeResponse} set.

Note that when used with HTTP connectors, this class maps to the "WWW-Authenticate" header. @author Jerome Louvel
