Session
A heavy-weight Session object representing an HttpSession. Session objects
relating to a context are kept in a
SessionCache
. The purpose of the
SessionCache is to keep the working set of Session objects in memory so that
they may be accessed quickly, and facilitate the sharing of a Session object
amongst multiple simultaneous requests referring to the same session id.
The SessionHandler
coordinates the lifecycle of Session objects with
the help of the SessionCache.- See Also:
