Preventing the Creation of a Session in a JSP Page</h3>
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.
<P> The <code>page</code> directive is used to prevent a JSP page from
automatically creating a session:
<pre>
<%-- Prevent the creation of a session --%>
<%@ page session="false">
<html>
<head><title>A Session-less JSP Page</title></head>
<body>
...
</body>
</html>
</pre>
