/**
 * Implementation of the <b>Manager</b> interface that makes use of a Store to swap active Sessions to disk. It can be
 * configured to achieve several different goals:
 * <ul>
 * <li>Persist sessions across restarts of the Container</li>
 * <li>Fault tolerance, keep sessions backed up on disk to allow recovery in the event of unplanned restarts.</li>
 * <li>Limit the number of active sessions kept in memory by swapping less active sessions out to disk.</li>
 * </ul>
 * If used with a load-balancer, the load-balancer must be configured to use sticky sessions for this manager to operate
 * correctly.
