ASP.NET MVC4移动网站正确显示本地主机没有部署服务器

我有一个ASP.NET MVC4站点的手机内容。当我部署此我的本地开发机器上，移动内容是我在Opera移动看到，当我去到localhost / mysite的。然而，当我部署此我实际的服务器，我看到的Opera Mobile的桌面版本。在我的Windows手机访问该网站时，我得到相同的桌面视图。

I have an ASP.NET MVC4 site with mobile content. When I deploy this on my local development machine, the mobile content is what I see in Opera Mobile when I go to localhost/mysite. However, when I deploy this to my actual server, I see the desktop version on Opera Mobile. I get the same desktop view when visiting the site on my Windows Phone.

我假设这不是一个DisplayModeProvider问题，因为网站的作品如预期本地主机上。我应该看什么？

I am assuming this is not a DisplayModeProvider issue as site works as expected on local host. What should I be looking at?

感谢。
