IIS如何处理ASP.net MVC请求？

I have a confusion over ASP.net MVC request handled by IIS. As every body says it built on top of ASP.net Engine. So only Url routing module and MvcRouteHandler makes a difference and they handled the request appropriately. I understand this.

我对IIS处理的ASP.net MVC请求感到困惑。正如每个机构都说它建立在ASP.net引擎之上。因此，只有Url路由模块和MvcRouteHandler有所不同，他们会适当地处理请求。我理解这一点。

But My Question is how IIS understand that it is MVC request . There is no extension like .aspx is given in url . So how does it maps to correct ISAPI DLL.

但我的问题是IIS如何理解它是MVC请求。在网址中没有像.aspx这样的扩展名。那么它如何映射到正确的ISAPI DLL。

I appreciate your help to clear my confusion.

感谢您的帮助以消除我的困惑。

These rules can be defined at any level in IIS. Most MVC applications define the handlers at the application level in the web.config file:

可以在IIS中的任何级别定义这些规则。大多数MVC应用程序在web.config文件中定义应用程序级别的处理程序：

<system.webServer>        
    <handlers>
      <add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit".../>
      <add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit".../>
      <add name="ExtensionlessUrlHandler-Integrated-4.0".../>
    </handlers>
</system.webServer>
