推荐答案

在会话中

指定会话可以保留的分钟数在服务器自动终止之前空闲。默认值为10分钟。 Session.Timeout没有硬编码限制。大多数Web管理员将此属性设置为8分钟。它不应设置为高于20分钟（特殊情况除外），因为每个打开的会话都保留在内存中。它也不应低于4分钟，因为客户很少在这段时间内回复，导致会话状态丢失。

In Session
Specifies the number of minutes that a session can remain idle before the server terminates it automatically. The default is 10 minutes. Session.Timeout has no hard-coded limit. Most Web administrators set this property to 8 minutes. It should not be set higher than 20 minutes (except in special cases) because every open session is holding onto memory. It should also not be set lower than 4 minutes because clients rarely respond within that time resulting in a loss of session state.

<configuration>
  <system.web>
     <sessionState timeout="20"></sessionState>
  </system.web>
</configuration>

如果用户在超时期限内没有刷新或请求页面，则会话结束。

并检查会话是否为在MasterPage加载事件中为null

If the user does not refresh or request a page within the time-out period, the session ends.
And check if session is null in MasterPage load event

if(Session["UserID"]==null)
Response.Redirect("Login.aspx");

用户

User

HTML <meta> Tag

能够重新加载当前页面很有用，它通常不是人们想要的元刷新标签。要重定向到新页面，语法与重新加载当前页面几乎相同：

While being able to reload the current page is useful, it is not typically what people want from the meta refresh tag. To redirect to a new page, the syntax is nearly the same as reloading the current page:

<meta http-equiv="refresh" content="600"> 

content =600 - 这是浏览器重新加载当前页面之前的时间量（以秒为单位）。这次会话将重定向到登录页面in null
