public class DummyMemcachedBackupSessionManager
extends MemcachedBackupSessionManager

This MemcachedBackupSessionManager can be used for debugging session deserialization - to see if serialized session data actually can be deserialized. Session data is serialized at the end of the request as normal (stored in a simple map), and deserialized when a following request is asking for the session. The deserialization is done like this (instead of directly at the end of the request when it is serialized) to perform deserialization at the same point in the lifecycle as it would happen in the real failover case (there might be difference in respect to initialized ThreadLocals or other stuff).

The memcached configuration (memcachedNodes, failoverNode) is not used to create a memcached client, so serialized session data will not be sent to memcached - and therefore no running memcacheds are required. Though, the memcachedNodes attribute is still required (use some dummy values).
