问题描述
我有一个基于 jsp servlet 的应用程序，会话时间超过 30 分钟，我想在有人有意或无意关闭浏览器窗口时立即使会话无效(操作系统关闭/从 tast 管理器关闭/关机)
I have a jsp servlet based application, with session time out of 30 mins, I want to invalidate the session as soon as a person closes the browser window intentionally or accidentally (OS shutdown/close from tast manager/powerdown)
我可以对此进行检查并使会话无效吗?
Can I put a check for that and invalidate the session?
推荐答案
无法处理这种情况.
有些浏览器提供此设置作为他们的首选项，但您无法以编程方式处理此设置.
There are some browsers which provide this setting as their preference , but you can't handle this programitically.
最大:
您可以在连接关闭后立即从与 gmail 中的 gtalk 相同的页面(可能是标题)进行投票.
You can make a poll from page(may be header) same as gtalk in gmail as soon as connection closes wipe that session out.
