New session created with every page request

Question

Hi,
I have an application running in portal framset. A user logins into a portal and has access to several applications, that are displayed in a frameset. My application is creating a new session for every page in the application. Of course, I can't keep session variables and a large amount of sessions are being created. What could be the reason for this, and is there a work around?
Thanks.

There is a chance the you have cookies turned off. Sessions are maintained via a jsessionid which is stored in a user cookie. If you (or another user) don't use cookies, then the session will be lost.
To fix this, every URL you use must be encoded, such that, if cookies are not used, the jsessionid is attached to the end of the URL. If you are using JSTL, the easiest way to do this is like this:
<c:url var="formAction" value="someOtherPage.jsp"/>
<form action="<c:out value="${formAction}"/>" method="GET">
<c:url var="nextPage" value="nextInLine.jsp"/>
<a href="<c:out value="${nextPage}"/>">Next</a> Or if you are not using JSTL, you can use scriptlets:
<%
  String formAction = response.encodeURL("someOtherPage.jsp");
%>
<form action="<%= formAction %>" method="GET">
<%
  String nextPage = response.encodeURL("nextInLine.jsp");
%>
<a href="<%= nextPage %>">Next</a>
