       When a webapplication is being shutdown, Tomcat issues an expire call to each session to 
       notify all the listeners. If you wish for all sessions to expire on all nodes when
       a shutdown occurs on one node, set this value to <code>true</code>.
       Default value is <code>false</code>.
