推荐答案

非常困难的任务:

• 使用超时非常小的会话/您将到期/

• use sessions with very smalll timeout /you will have expiration/

使用隐藏的脚本/iframe ping服务器/您将建立连接/

use hidden script/iframe to ping server /you will have connection/

在窗口中处理onunload事件/可以绕过/

handle onunload event in window /can be bypassed/

代码示例:

window.onunload = function ()  
{    
    if((window.event.clientX<0) && (window.event.clientY<0)) {

       window.open("logoff.aspx");                  
    }    
}
