 4.这个就是处理 【托管程序】的入口方法了  

[SecurityPermission(SecurityAction.LinkDemand, Unrestricted=true)]
public int ProcessRequest(IntPtr ecb, int iWRType){
    IntPtr zero = IntPtr.Zero;
    if ( iWRType == 2 ){zero = ecb;ecb = UnsafeNativeMethods.GetEcb(zero);}
    ISAPIWorkerRequest wr = null; //ISAPIWorkerRequest : HttpWorkerRequest
    try{
        bool useOOP = iWRType == 1;
        wr = ISAPIWorkerRequest.CreateWorkerRequest(ecb, useOOP);//将 ecb 句柄封装成 HttpWorkerRequest 的 源码在此 ！！！
        wr.Initialize();
        string appPathTranslated = wr.GetAppPathTranslated();
        string appDomainAppPathInternal = HttpRuntime.AppDomainAppPathInternal;

        if ((appDomainAppPathInternal == null) || StringUtil.EqualsIgnoreCase(appPathTranslated, appDomainAppPathInternal))
        {
            HttpRuntime.ProcessRequestNoDemand(wr);
            return 0;
        }

        object[] args = new object[] { appDomainAppPathInternal, appPathTranslated };
        HttpRuntime.ShutdownAppDomain(ApplicationShutdownReason.PhysicalApplicationPathChanged, SR.GetString("Hosting_Phys_Path_Changed", args));
        return 1;
    }catch (Exception exception){
        try{ WebBaseEvent.RaiseRuntimeError(exception, this); }catch{}
        if ( (wr == null) || !(wr.Ecb == IntPtr.Zero) ){throw;}
        if ( zero != IntPtr.Zero ){UnsafeNativeMethods.SetDoneWithSessionCalled(zero);}
        if ( exception is ThreadAbortException ){Thread.ResetAbort();}
        return 0;
    }
}
