自2008年10月以来，我一直面临着这个问题，但是最终我明白了为什么吗?与其添加我上面在问题中添加的模块，不如使用针对IIS7的以下新模块语法(哥达迪使用IIS7进行Windows托管)

I was facing this problem since last October 2008, but finally I got this why? Instead of adding modules like I have added above in my question, use the following new module syntax made for IIS7 (godaddy is using IIS7 for windows hosting)

<configuration>
   <system.webServer>
      <modules>
         <add name="Header" type="Contoso.ShoppingCart.Header"/>
      </modules>
   </system.webServer>
</configuration>

将所有模块放在这里，您就完成了！很好，很完美！

Place all your modules under here and you're done! It's nice and works perfect!

"@ Jon Skeet"不需要模块的名称空间，即使没有名称空间，您也可以使用它！

And "@Jon Skeet" there is no need to have namespace for modules, even without namespace you can get it work!
