Описание: HttpSession with Cookies (Session Tracking/Handling Technique) : HttpSession object allocates memory on server on one per browser window(client window basis).

Here HttpSession object means its the object of underlaying container supplied java class that implements javax.servlet.http.HttpSession interface.

This HttpSession object remembers client data across the multiple requests during a session in the form of session attribute values.
