推荐答案

有三种方法为了实现我已经在我自己的项目中使用的功能：

（1）：将此代码添加到您的每个ActionResult方法中。使用此用户无法通过在LogOut之后单击浏览器的向后图标返回

There are three ways for doing that functionality which i m already using in my own project:
(1):Add this code to your every "ActionResult" method. By using this user can not go back by clicking backward icon of browser after "LogOut"

public void SetPageCacheNoStore()
{
    Response.Cache.SetCacheability(HttpCacheability.NoCache);
    Response.Cache.AppendCacheExtension("no-store, must-revalidate");
    Response.AppendHeader("Pragma", "no-cache");
    Response.AppendHeader("Expires", "0");
}

（2）：在启动时的每个方法中使用此代码来检查Session是否被销毁。

(2):Use this code in every method at startup for checking Session destroyed or not.

if (Session["UserName"] == null)
                {
                    return RedirectToAction("Login", "Account");
                }

（3）：在每个视图或部分视图中使用此代码，例如补充工具栏在每个视图中使用。

(3):Use this code in every view or in a "Partial" view like "Sidebar uses in every view".

string viewNames = Session["UserName"];
   if (ViewNames == null)
   {
       <script src="~/Scripts/jquery-1.11.1.min.js"></script>
       <script>

（document）.ready（function（）{
window.location.href =../Account/Login;
}）;
< / script>

}

(document).ready(function () { window.location.href = "../Account/Login"; }); </script> }

我希望通过使用所有这些解决方案，您的问题将得到解决。
