| 30 * Provides a way to tell the runtime about stickiness of requests. In a | |
| 31 * HA environment, a client's requests need to land on the same instance so | |
| 32 * that a {@link com.sun.org.glassfish.ha.store.api.BackingStore} entry for a key is | |
| 33 * accessed/modified from the same instance. | |
| 34 * | |
| 35 * <p> | |
| 36 * A web service feature may implement this interface. JAX-WS runtime | |
| 37 * checks if any feature needs stickiness of requests, and if HA is configured | |
| 38 * ({@link HighAvailabilityProvider#isHaEnvironmentConfigured()}), it will take | |
| 39 * an appropriate action. For example, in servlet transport, it would create | |
| 40 * JSESSIONID cookie so that a typical loadbalancer would stick the subsequent | |
| 41 * client requests to the same instance. | |
