/**
 * Provides a way to tell the runtime about stickiness of requests. In a
 * HA environment, a client's requests need to land on the same instance so
 * that a {@link org.glassfish.ha.store.api.BackingStore} entry for a key is
 * accessed/modified from the same instance.
 *
 * 

* A web service feature may implement this interface. JAX-WS runtime * checks if any feature needs stickiness of requests, and if HA is configured * ({@link HighAvailabilityProvider#isHaEnvironmentConfigured()}), it will take * an appropriate action. For example, in servlet transport, it would create * JSESSIONID cookie so that a typical loadbalancer would stick the subsequent * client requests to the same instance. * * @author Jitendra Kotamraju * @since JAX-WS RI 2.2.2 */ public interface StickyFeature { }
