How to Disable session in JSP page ?


SCJP 1.5/1.6 Exam Kit
SCWCD 1.5 Exam Kit

Disabling the session in some pages will improve the performance of your JSP container.

Every time a JSP is requested, JSP creates an HttpSession object to maintain state for each unique client. The session data is accessible in the JSP as the implicit session object. In JSPs, sessions are enabled by default.
By default <%@ page session="true" %>

Session object uses the server resources. Each session object uses up a small amount of system resources as it is stored on the server side. This also increases the traffic as the session ID is sent from server to client. Client also sends the same session ID along with each request. If some of the JSP pages on your web site are getting millions of hits from internet browser and there is not need to identify the user, so its better to disable the session in that JSP page.


You can tell the container to disable session in the JSP file by setting the session attribute to false. Set the session attribute of the page directive to false.

<%@ page session="false" %>

<%@ page language="java" session="false"%>
