SplitHttpSessionCollection

public class TraditionalHttpSessionCollection
extends AbstractHttpSessionCollection

An implementation of HttpSessionCollection that manages session objects as individual units that contain all of their own attributes, as if the session were a single serializable object, however with some optimizations for attribute serialization and deserialization.

The collection uses two configurable named caches to manage its session information in the cluster:

• "session-storage": The cache of clustered session models. This cache should be configured as an unlimited size cache, although it is strongly suggested that it be arranged in a tiered memory/persistent manner by using the overflow map functionality of Coherence, or even using size-limited caching with read-through/write-behind to a database (if sessions should survive a full cluster take-down/restart).
