title: Catch request to a file in content folder to handle with controller action
body: <p>I got a third party widget library I have to use. This library has a hardcoded string to a file. Is it possible to intercept this request with routes? My try looked like this:</p>
  
  <pre><code>routes.MapRoute(name: "ribbonbar",
                  url: "Content/Ribbon/Scripts/Ribbon.Tabs.foo",
                  defaults: new { controller = "Ribbon", action = "Index" });
  </code></pre>
  
  <p>But I only got a 404. Is it impossible or do I have mixed something up?</p>
