Synopsis

Description

The session variable is assigned a reference to the HttpSession object that represents the current client session. Information stored as HttpSession attributes corresponds to objects in the JSP session scope.

By default, the session persists for a time period specified in the web application deployment descriptor, across more than one page request from the user. The container can maintain a session in many ways, such as using cookies or rewriting URLs.
