Looking Forward to JavaOne Sunday: JUG Forums, NetBeans Day, GlassFish, Technical Keynotes, Duke's Choice Awards

javax.servlet.http.HttpSession provides a way to identify an user across multiple HTTP requests and to store user specified information. In other words, it provides a support of stateful communications with the stateless HTTP protocol.
For security and memory management, sessions need to be invalidated at a certain time. There are two related methods in HttpSession.
