Simply follow the instructions for using sessions that you will find in
any book or tutorial about servlets.
Basically, what that means to a servlet developer is:
* In your doGet() or doPost() method, call:
HttpSession session = request.getSession(true);
to create a new session if it does not exist, or
HttpSession session = request.getSession(false);
if you only want an existing session if there is one.
* If you need to run on browsers that do not support cookies,
you must use URL rewriting on all your hyperlinks. For example:
writer.println("<a href=\"" +
response.encodeURL("/servlet/MyServlet") + "\">My link</a>");
