Preventing the Creation of a Session in a JSP Page
Posted by Customer Service on 25 May 2005 12:59 AM
By default, a JSP page will automatically create a session for the request if one does not exist. However, sessions consume resources and if it is not necessary to maintain a session, one should not be created. For example, a marketing campaign may suggest the reader visit a web page for more information. If it is anticipated that a lot of traffic will hit that page, you may want to optimize the load on the machine by not creating useless sessions.

The page directive is used to prevent a JSP page from automatically creating a session:

    <%-- Prevent the creation of a session --%>
    <%@ page session="false">
    
    <html>
    <head><title>A Session-less JSP Page</title></head>
    <body>
    ...
    </body>
    </html>
