cannot retrieve session attributes from ajax call to servlet

I am having problem while retrieving session attributes in servlet called via ajax cal.

$('#homemainSearchField').submit(function(){

                $.get("./CheckNoOfSearch",function(data){
                    checkLimitation(data);
                });
            });

In CheckNoOfSearch servlet i am trying to retrieve some session attributes, but all session attributes are null but its not that i haven't set it.

The servlet code is

protected void processRequest(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        try {
            HttpSession session = request.getSession();
            int noOfSearch = 0;
            if (session.getAttribute("auth") != null && session.getAttribute("type") != null) {
                System.out.println("Session found");
            }

            out.print(noOfSearch);
        } finally {
            out.close();
        }
    }

HttpSession is identified by jsessionid, you have to pass jsessionid to the server using Cookie header or URL rewriting.

You can get the session in your servlet straight.

public class MyServlet extends HttpServlet {

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        HttpSession s = request.getSession();
    }
}
