HttpContext.Current.ApplicationInstance.CompleteRequest 似乎什么也没做。我错过了什么？

例如，尽管在每个有趣的事件期间都会调用 CompleteRequest，但以下所有事件仍然在一个简单的测试页面上运行。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;

namespace LifeCycle
{
    public partial class _Default_NoMasterPage : System.Web.UI.Page
    {
        private int count = 0;

        protected override void OnInit(EventArgs e)
        {
            nextLabel("InitBeforeBase");
            base.OnInit(e);
            HttpContext.Current.ApplicationInstance.CompleteRequest();
            nextLabel("Init");
        }

        protected override void OnInitComplete(EventArgs e)
        {
            nextLabel("InitCompleteBeforeBase");
            base.OnInitComplete(e);
            HttpContext.Current.ApplicationInstance.CompleteRequest();
            nextLabel("InitComplete");
        }

        protected override void OnLoad(EventArgs e)
        {
            nextLabel("OnLoadBeforeBase");
            base.OnLoad(e);
            HttpContext.Current.ApplicationInstance.CompleteRequest();
            nextLabel("OnLoad");
        }

        protected override void OnLoadComplete(EventArgs e)
        {
            nextLabel("OnLoadCompleteBeforeBase");
            base.OnLoadComplete(e);
            HttpContext.Current.ApplicationInstance.CompleteRequest();
            nextLabel("OnLoadComplete");
        }

        protected override void OnPreInit(EventArgs e)
        {
            // can't add a control to the page during OnPreInit as the other page control doesn't exist yet.
            base.OnPreInit(e);
        }

        private void nextLabel(string eventName)
        {
            string lbl = "" + ++count + " " + eventName + " at " + DateTime.Now.ToLongTimeString() + "";
            System.Web.UI.HtmlControls.HtmlGenericControl c = new HtmlGenericControl("div");
            c.InnerText = lbl;
            Page.Controls.Add(c);
        }
    }
}

所以事实证明我对 completerequest 有一个根本的误解。CompleteRequest 跳过了 IIS HTTP 管道链的其余部分，但 ASP.NET 页面处理程序事件生命周期完成了运行，因为它只是 HTTP 管道链的一部分，没有任何东西告诉这部分停止。
