title: Redirect specific routes to page if they don't exist with laravel 4
body: <p>I have a route that needs to be redirected to another page if the data they're pulling doesn't exist. The route is:</p>
  
  <pre><code>Route::get('{link}/{data}', 'LinkController@getLink');
  </code></pre>
  
  <p>Where <code>{link}</code> and <code>{data}</code> are model bound with:</p>
  
  <pre><code>Route::model('link', 'Link');
  Route::model('data', 'Data');
  </code></pre>
  
  <p>As is, when the data for this link doesn't exist it 404's, and if it does exist, it's taken to the page as it should. What I would like to do is redirect to another page if the link would otherwise 404. I've found suggestions on how to do this globally, but I only want it to happen on this one route.</p>
  
  <p>Any ideas?</p>
