Traditionally Sessions belong to a specific ServletContext. The handler mechanism alone has no ServletContext.
The specialized handler ServletContextHandler does however. And that is where Servlet / Filters / Listener / Sessions etc are all added to. The constructor of the ServletContextHandler has an option to turn on Session handling support (not enabled by default). ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS); If you want to configure the Session handling for different caches, different storage, etc.. That's done via the SessionManager on the ServletContextHandler.
