Sessions in other pages

Session are not belong to pages, it seems you have set your scoop as request (request scoop is for a page invocation)

simply track your session with request.getSession() for example
in page 1:

<![CDATA[<%
  request.getSession().setAttribute("name","value");
%>]]>

and then get the session values in page 2

<![CDATA[<%
 String name=(String) request.getSession().getAttribute("name");
%>]]>

the default session timeout is 30 min while you can extend it, but for having long time data, use cookies instead
