The request might not be processed by the UrlRoutingModule. Try adding this to your web.config, making this module to handle all process requests:

<modules>
  ...
  <remove name="UrlRoutingModule-4.0" />
  <add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule" preCondition="" />
  ...
</modules>
