Package net.officefloor.web.session.store

Class MemoryHttpSessionStore

java.lang.Object

net.officefloor.web.session.store.MemoryHttpSessionStore

All Implemented Interfaces:

HttpSessionStore

public class MemoryHttpSessionStore
extends Object
implements HttpSessionStore

HttpSessionStore that contains state of the HttpSession within memory.

This is a very basic implementation that keeps all HttpSession instances in memory. Though this may provide a very fast solution it suffers from issues such as:

1. OutOfMemoryError if too many/large HttpSession instances
2. state is not shared with other JVMs (especially for clustered environments)

This is useful in light load testing environments (such as unit tests).
