Enclosing class:

AbstractHttpSessionCollection

public static class AbstractHttpSessionCollection.ExitAgent
extends AbstractInvocable
implements ExternalizableLite

This agent is used to request the other servers in the cluster to unlock the specified session ID.

Note: This must be a static class, for serialization purposes. Were it not static, it would "drag" the entire session collection with it across the cluster.
