public interface StickyFeature
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 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
(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.
