Question

它不与此Prevent user from seeing previously visited secured page after logout重复。我研究过它以找出一些有用的东西。但这与我的问题无关。如果我在浏览器上禁用java脚本，这个重复的票证解决方案对我来说根本不起作用。请建议我，以便我可以进行正确的注销会议。我尝试了很多注销代码，但没有任何工作在注销会话上。当我点击回来时，它将是正常的会话。我的示例代码是，

＆＃34;菜单中的退出链接：＆＃34;

<a href="LogOut.do"><i class="fa fa-sign-out"></i><b>&nbsp;Logout</b></a>

＆＃34;退出Servlet代码＆＃34;：

public class LogOutServlet extends HttpServlet {

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub


         response.setHeader("Cache-Control","no-cache"); //Forces caches to obtain a new copy of the page from the origin server
         response.setHeader("Cache-Control","no-store"); //Directs caches not to store the page under any circumstance
         response.setDateHeader("Expires", 0); //Causes the proxy cache to see the page as "stale"
         response.setHeader("Pragma","no-cache"); //HTTP 1.0 backward compatibility
         HttpSession session=request.getSession();
         String userName = (String) session.getAttribute("customerDetails");
         if (null == userName) {
            request.setAttribute("Error", "Session has ended.  Please login.");
            RequestDispatcher rd = request.getRequestDispatcher("logout.jsp");
            rd.forward(request, response);
         }


    }

}

＆＃34; logout.jsp＆＃34;

<% session.invalidate(); %>

我尝试过许多不同的代码。但是当我点击浏览器的后退按钮时，它仍然正常显示主页。请帮助找到退出的最佳代码。
