如何在asp.net中结束会话？ [英] how to end a session in asp .net?

问题描述

您好，我有两个webforms，一个是登录页面，另一个是主页。每当我点击主页中的注销按钮时，它会重定向到登录页面，如果我点击浏览器中的后退按钮，它会重定向到主页，这不应该发生。现在我的疑问是，每当我点击浏览器中的后退按钮（从主页退出后），它将重定向到登录页面而不是主页。谢谢........



登录页码：

Hello, I have two webforms one is login page and another is home page. Whenever i clicks on logout button in "home page" it redirects to "login page" and if i clicks on "back" button in browser it redirects to home page which shouldn''t be happened. Now my query is that whenever i would click "back" button in browser(after logging out from home page)it would redirect to login page rather than home page. Thanks........

LogIn Page Code:

try
        {
            Session["ename"] = TextBox1.Text;
            cn.Open();
            SqlCommand SqlCmd = new SqlCommand("SELECT * FROM empregd WHERE ename='" + TextBox1.Text + "' AND password='" + TextBox2.Text + "'", cn);
            SqlDataAdapter SqlDa = new SqlDataAdapter(SqlCmd);
            SqlDataReader SqlDr = SqlCmd.ExecuteReader();
            if (SqlDr.Read())
            {
                Response.Redirect("http://localhost:49871/WebSite7/Default6.aspx");
            }
            SqlDr.Close();
            cn.Close();
            TextBox1.Text = "";
            TextBox2.Text = "";
        }
        catch (Exception ex)
        {
            throw ex;
        }
