Jeff-
One way you could to this is by passing some sort of token (name/value pair)
to indicate they are a "returning client". New clients would have this
value null. Then you do a getSession(true) for new clients and
getSession(false) for "returning clients".

Subject: Determining whether a user's session ended or is new???
My doGet method is as follows:
public void doGet(HttpServletRequest req,
HttpServletResponse resp)
throws ServletException, java.io.IOException
{
HttpSession session = req.getSession(false);
if (session == null) {
// No action was given from a page. Present the
// initial login page.
resp.sendRedirect(resp.encodeRedirectUrl(pageLogin));
}
else {
java.io.PrintWriter out =
new java.io.PrintWriter(resp.getOutputStream());
// We have a user for the session. Display the
// main page
createMain(out,session);
out.flush();
out.close();
}
}
>>>>>>>>>>>>>>>>>
As you can see it basically redirects back to the login screen if the
session is null, or re-displays the main page if it's active.
Two Critical Questions I need answered:
1.) If a user's session is null, how do I determine if their session
expired OR if they just came to the site and haven't started a session yet.
If a user's session timed out, I want to send them to a "session expired"
page, versus the login page.
2.) My main page is frame-based. Whenever the page reloads, it goes to the
page that I specified in my createMain function. I want it to stay on the
same page that I was currently on. Is there a way?
Your help would be IMMENSELY appreciated.
Thank you!
