session is an object used by the servlet to track a user
interaction with web application across multiple HTTP
requests.
session is a collection or sequence of HTTP requests over a
period of time between client and webserver.when a session
is created,its life time is also set,defalut being 3 minute.
Upon expiration,session is destroyed,its resources returned
back to the engine.sessions can be prematurely destroyed by
the developer.
If a session is configured to last for 30 min.Upon
expired,client will need to start a new session.Each
session requires unqiue session id that can be used by the
client.
