URL Routing problem with ASP.NET 4 on GoDaddy IIS 7

If you get 404 errors when trying to add URL Routing with ASP.NET 4 (Web Forms) on GoDaddy, simply reference the relevant modules in your web.config file:

    <modules runAllManagedModulesForAllRequests="true"> 
      <remove name="UrlRoutingModule" /> 
      <add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web, 
        Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> 
    </modules> 
    <handlers> 
      <add name="UrlRoutingHandler" 
        preCondition="integratedMode" 
        verb="*" path="UrlRouting.axd" 
        type="System.Web.HttpForbiddenHandler, System.Web,  
        Version=2.0.0.0, Culture=neutral,  
        PublicKeyToken=b03f5f7f11d50a3a"/> 
    </handlers> 

Add this to the system.webServer node.
