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