public class GigaSessionManager
extends org.eclipse.jetty.server.session.AbstractSessionManager

GigaspacesSessionManager A Jetty SessionManager where the session data is stored in a data grid "cloud". On each request, the session data is looked up in the "cloud" and brought into the local space cache if doesn't already exist, and an entry put into the managers map of sessions. When the request exists, any changes, including changes to the access time of the session are written back out to the grid.
