推荐答案

您需要确保登录后的页面（那些只能登录后可以访问）在浏览器不会被缓存：

You will need to make sure the pages behind the login (those that can only be accessed after login) are not cached in the browser:

Page.Response.Cache.SetCacheability(HttpCacheability.NoCache);

如果使用窗体身份验证，则还需要摒弃了会议，并注销：

If using forms authentication, you will also need to abandon the session and logout:

Session.Abandon();
FormsAuthentication.SignOut();
