What is the session Object in JSP?

JSPJava 8Object Oriented ProgrammingProgramming

The session object is used to track a client session between client requests.

JSP makes use of the servlet provided HttpSession Interface. This interface provides a way to identify a user across.

  • a one-page request or
  • visit to a website or
  • store information about that user

By default, JSPs have session tracking enabled and a new HttpSession object is instantiated for each new client automatically. Disabling session tracking requires explicitly turning it off by setting the page directive session attribute to false as follows −

<%@ page session = "false" %>

The JSP engine exposes the HttpSession object to the JSP author through the implicit session object. Since the session object is already provided to the JSP programmer, the programmer can immediately begin storing and retrieving data from the object without any initialization or getSession().
