如何完全清除会话，使用户注销后无法返回? [英] How to clear session completely , so user can not return back after logout?

问题描述

专家，

在asp.net网站上，我使用了母版页，在其中我为注销选项设置了一个按钮.

在母版页加载事件中，我为按钮文本(登录或注销)编写以下代码.

Hi Expert,

In asp.net website i have use masterpage where i put one button for logout option.

On master page load event i write following code for button text(login or logout).

if (Session["session_log_id"] == null)
        {
            lblUserName.Text = "";
            buttLogin.Text = "Login";
        }
        else
        {
            lblUserName.Text = "<font color=#666666 size=2 face=Arial, Helvetica, sans-serif>Hi </font> , <font color=#822228 size=2 face=Arial, Helvetica, sans-serif>" + Session["session_logged_username"].ToString() + "</font>";
            buttLogin.Text = "Logout";
        }

在该按钮的onclick事件上，我编写代码

On that buttons onclick event,i write code

Session.RemoveAll()

并将用户重定向到首页.

到此为止对我来说一切正常.但是之后，当我按下返回"按钮时，它将返回到该页面并再次显示注销按钮.

在每个页面加载事件中，我都编写了类似这样的代码来检查Wheather会话是否存在并防止未登录的用户.

and redirect the user to Home page.

Upto this working fine for me.But after that when i hit back button it return to that page and show logout button again.

on each page load event i have write code like this to check wheather session is exist or not and prevent the unlogged user.

if (Session["session_log_id"] == null)
        {
            lblUserName.Text = "";
            buttLogin.Text = "Login";
        }
        else
        {
            lblUserName.Text = "<font color=#666666 size=2 face=Arial, Helvetica, sans-serif>Hi </font> , <font color=#822228 size=2 face=Arial, Helvetica, sans-serif>" + Session["session_logged_username"].ToString() + "</font>";
            buttLogin.Text = "Logout";
        }
