Hi,

Following Question from Enthuware mock exam.

Which of the following is NOT a technique used for maintaining sessions?

a.HttpSession objects
b.HttpSessionActivationListener

I selected a but the answer says b why?. b is used in session migration which is also a type of session management but answer says b.

Thanks

HttpSession Object is where you keep information about particular session. Whereas HttpSessionActivationListener used for before Passivation/after the Activation in order to let the listeners of that kind inform about the event.
