The ClusterListener object

The org.apache.catalina.ha.ClusterListener base class lets you listen in on messages that are received by the Cluster component.

When using the DeltaManager, the messages are received by the Cluster object and are propagated to the to the manager through this listener.

Listens for session Id changes. This listener is only used if you are using mod_jk along with the jvmRoute attribute where the session Id can change. In the event of a change, the JvmRouteBinderValve will broadcast the session change and it will get picked up by this listener.
