public class Session extends Object
Sessions persist between HTTP requests for a single browser session. They are deleted when the browser is closed, or they time-out. Session cookies are used to maintain sessions using a secure UUID.
Sessions can be used to maintain data for a browser session, e.g. a shopping basket.
The context must have first been routed to a SessionHandler
for sessions to be available.
