嗨，我一直在使用国际版：ASP.NET MVC 3 Internationalization - Part 2 (NerdDinner)： http ://afana.me/post/aspnet-mvc-internationalization-part-2.aspx
不幸的是，这包含一个主要错误。问题是我已经下载了代码/项目并进行了构建并将其发布到本地文件夹（有一些小错误需要修复才能发布），然后将文件上传到我的 webhotel。主页看起来还可以，但后来我查看了谷歌网站管理员工具并在网站上进行了爬网，发现网站中没有一个页面可以被索引，甚至根节点也无法被谷歌爬虫获取：
这是我在尝试获取根 (www.thehomepage.com) 或站点中的任何页面时遇到的错误：
页面无法访问

希望有人可以看看并告诉什么是拒绝谷歌爬虫，这样我就无法获取任何东西。
