HttpSession
After this method executes, and if the new object implements HttpSessionBindingListener, the
container calls HttpSessionBindingListener.valueBound. The container then notifies any
HttpSessionAttributeListeners in the web application.
If an object was already bound to this session of this name that implements
HttpSessionBindingListener, its HttpSessionBindingListener.valueUnbound method is
called.
If the value passed in is null, this has the same effect as calling removeAttribute().

cookies, then a session would be new on each request.isNew in interface HttpSessiontrue if the server has created a session, but the client has not yet joinedpublic Session getSession()
