<p>
The <code>org.apache.catalina.ha.ClusterListener</code> base class
lets you listen in on messages that are received by the <code>Cluster</code> component.
</p>
</section>
<section name="org.apache.catalina.ha.session.ClusterSessionListener">
<p>
When using the DeltaManager, the messages are received by the Cluster object and are propagated to the
to the manager through this listener.
</p>
</section>
<section name="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener">
<p>
Listens for session Id changes. This listener is only used if you are using mod_jk
along with the <code>jvmRoute</code> attribute where the session Id can change.
In the event of a change, the <code>JvmRouteBinderValve</code> will broadcast the
session change and it will get picked up by this listener.
