Class TraditionalHttpSessionCollection

java.lang.Object
com.tangosol.util.Base
com.tangosol.coherence.servlet.AbstractHttpSessionCollection

All Implemented Interfaces:

CoherenceHttpSessionCollection, HttpSessionCollection

Direct Known Subclasses:

SplitHttpSessionCollection

Deprecated. In releases following 3.6 customization will be declarative.

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).
• "session-death-certificates": A cache of previously used session IDs. This cache should be configured to expire its entries after an acceptable period of time (e.g. one hour or one day), and probably should be size-limited as well (e.g. ten thousand entries).
