推荐答案

当你点击浏览器后退按钮，它从高速缓存无法从服务器带来的页面。但是，用户将无法后退按钮后显示的页面上执行任何操作。

When you click on browser back button, it brings page from cache not from server. But user will not be able to perform any action on page displayed after back button.

如果你仍然想页面不应该显示你应该删除缓存。这是一个最好的做法。这里是code。 （在文件的Global.asax.cs写入）

If you still want page should not be displayed you should remove cache. It's a best practice. Here is the code. (Write in Global.asax.cs file)

 protected void Application_BeginRequest()
    {
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.Cache.SetExpires(DateTime.UtcNow.AddHours(-1));
        Response.Cache.SetNoStore();
    }

写这篇code用户将看不到后pressing后退按钮previous页面后。

After writing this code user will not see previous page after pressing back button.

上面写尽Session对象明确的code是正确的。无需改变任何事情。
