默认会话到期超时？ [英] Default session expiration timeout?

问题描述

默认情况下，当您关闭浏览器时， JSESSIONID cookie已过期，但关联的 HttpSession

对于大多数容器，默认为30分钟，您可以通过配置

< session-config>

 < session-config> 
< session-timeout> 10< / session-timeout> 
< / session-config> 
  

上述示例将服务器端会话超时更改为10分钟。因此，换句话说，当客户端不与服务器交互超过10分钟（即使浏览器保持打开那么长时间），那么会话将在服务器端过期。

By default the JSESSIONID cookie is expired when you close the browser, but how long is the associated HttpSession really valid on the server side?

解决方案

It defaults to 30 minutes on most containers which you can configure by <session-config> in your webapp's web.xml.

<session-config>
    <session-timeout>10</session-timeout>
</session-config>

The above example will change the server side session timeout to 10 minutes. So in other words, when the client do not interact with the server for more than 10 minutes (even though the browser is kept open that long), then the session will expire on the server side. Any next request will create a new session.
