public class InvalidateSessionAndRetryOn401AndLogoutOnClose
extends BackoffLimitedRetryHandler

If the credentials supplied in the authentication header are invalid, or if the token has expired, the server returns HTTP response code 401. The token expires after a configurable interval of api inactivity. The default is 30 minutes after the token is created. After the token expires, you must log in again to obtain a new token.
