org.restlet.data.ChallengeMessage

org.restlet.data.ChallengeResponse

public final class ChallengeResponse
extends ChallengeMessage

Authentication response sent by client to an origin server. This is typically following a ChallengeRequest sent by the origin server to the client.

Sometimes, it might be faster to preemptively issue a challenge response if the client knows for sure that the target resource will require authentication.

Note that when used with HTTP connectors, this class maps to the "Authorization" header.
