public class HashSessionManager
extends AbstractSessionManager

HashSessionManager An in-memory implementation of SessionManager.

This manager supports saving sessions to disk, either periodically or at shutdown. Sessions can also have their content idle saved to disk to reduce the memory overheads of large idle sessions.

This manager will create it's own Timer instance to scavenge threads, unless it discovers a shared Timer instance set as the "org.eclipse.jetty.server.session.timer" attribute of the ContextHandler.
