Introduction

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

org.apache.catalina.ha.session.ClusterSessionListener

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

org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener

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.
