推荐答案

你无法阻止后面的密钥在浏览器中工作 - 它从它的内部缓存中提取页面所以它将返回登录页面。

但是，你可以在Page_Load事件中将登录页面设置为不可缓存：

You can't prevent the back key working in the browser - it pulls pages from it's internal cache so it will return to login pages.
However, you can set the Login page to uncacheable in the Page_Load event:

Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1));
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetNoStore();

然后检查您的用户是否已登录。如果是，请将他重定向到您的主页（或其他合适的主页）

and then check if your user is logged in. If he is, redirect him to your Home page (or another suitable one)
