我在global.asax中注意到了这一点

void Session_End(object sender,EventArgs e)
{
    // Code that runs when a session ends. 
    // Note: The Session_End event is raised only when the sessionstate mode
    // is set to InProc in the Web.config file. If session mode is set to StateServer 
    // or sqlServer,the event is not raised.
}

我想了解为什么会话模式是StateServer或sqlServer时没有捕获/引发Session_End事件？
