I have a problem in sessions. When ever I logout the session is ended but then when the browsers back button is pressed I am getting the previous page. I am using jsp servlet technology and my code for logout is given below 

                    request.getSession().invalidate();
        response.setHeader("Cache-Control","no-cache"); 
        response.setDateHeader("Expires", 0);
        response.setHeader("Pragma","no-cache"); 
        response.sendRedirect("home.jsp");

can anybody tell me where is the problem and what will be the solution for this problem?

Do you set the cache headers only on the logout page? If so, you need to put those on each page since the page you were coming from does not have them and will be cached.
