I have set app_offline.htm to my root directory and it works nicely to shut the site down and only show that page. Knowing for some frameworks (ASP.Net 2), this file will yield error 404 instead of 503, I want to check what code does my site return (for SEO purpose). However, when I enter a file url, instead of return me any error, it always goes back/redirects to the app_offline page automatically. How could I check to see my app pool is returning 404 or 503 now?
我已经将app_offline.htm设置为我的根目录，它可以很好地关闭网站，只显示该页面。知道一些框架（ASP.Net 2），这个文件将产生错误404而不是503，我想检查我的网站返回什么代码（用于SEO目的）。但是，当我输入文件网址时，它不会返回任何错误，而是会自动返回/重定向到app_offline页面。我怎么能检查我的应用程序池现在返回404或503？
P.S. I heard ASP.NET 4 (the one I use) is now always return 503. But I just want to double make sure.
附：我听说ASP.NET 4（我使用的那个）现在总是返回503.但我只想双倍确认。
Thanks!
谢谢！
