如何在部署期间显示维护页面？

I want to plan a schedule maintenance down time on one of my production asp.net website hosted on IIS windows server 2003.

我想在IIS windows server 2003上托管的一个生产asp.net网站上计划一个计划维护停机时间。

I think this is the preferred behavior:

我认为这是首选行为：

All request to http://www.x.com including www.x.com/asb/asd/ will be redirected to a notification page (site is currently down. come back later)
所有对http://www.x.com的请求（包括www.x.com/asb/asd/）都将被重定向到通知页面（网站目前已关闭。稍后再回来）
The maintenance will take around an hour. how do I ensure for having this redirection to maintenance page to have the least impact to SEO/google ranking
维护大约需要一个小时。如何确保将此重定向到维护页面以对SEO / google排名产生最小影响
Preferrably I want to be able to quietly test the production site before it goes back 'live'
我希望能够在“生活”回归之前悄悄地测试生产现场
Preferrably I dont want to rely on pointing DNS elsewhere.
我更不希望依赖指向其他地方的DNS。
To make it simple please pretend that I don't have any other hardware in front of the web servers (i.e load balancer, firewall etc)
为简单起见，请假装我在Web服务器前没有任何其他硬件（即负载平衡器，防火墙等）

An idea would be:

一个想法是：

to create another app on the same web server
在同一个Web服务器上创建另一个应用程序
create httpmodule or httphandler to handle any url request and 302 redirect them to the maintenance page
创建httpmodule或httphandler来处理任何url请求，302将它们重定向到维护页面
