title: MVC getting a 404 error for page but page still displays correctly
body: <p>I'm having a very very strange problem. On my localhost MVC site, the page loads and displays fine, but in Firebug the very first line in the Console tab says...</p>
  
  <pre><code>"NetworkError: 404 Not Found - http://localhost:11634/clay-test-3"
  </code></pre>
  
  <p>... where clay-test-3 is the URL of the page.</p>
  
  <p>I've used routedebugger to check the route, and everything there is working fine. Well, obviously it would have to be, because it's finding its way to the correct controller and the correct action and is generating the view.</p>
  
  <p>Unfortunately on the production site, all that comes up for the same page is just the standard IIS 404 error page, no routedebugger, no errors being logged in Elmah.</p>
  
  <p>If someone could explain to me how (on localhost) I can get a 404 error AND THE PAGE STILL DISPLAYS FINE, that might help me track down the problem.</p>
  
  <p>I'm assuming the issue is within the controller, but I am as yet to find a significant difference between this controller and the other, functioning, controllers on the site.</p>
  
  <p>My local machine is running IIS 10.0, the production box IIS 8.0.</p>
  
  <p>Thanks for your time!</p>
