title: requesting cloudinary resource gives CORS errors
body: <p>I have a laravel/lumen server managing uploads of my cloudinary resources. I'm also using the server as an API endpoint for my front end app. One of the endpoints returns a file from Cloudinary. I'm doing this by redirecting the request to the Cloudinary resource. However my app is failing because there are no CORS headers on the redirected resource.  </p>
  
  <pre><code>return redirect()-&gt;to("https://res.cloudinary.com/gates/raw/upload/" . $upload-&gt;id);
  </code></pre>
  
  <p>the error i get is:  </p>
  
  <pre><code>Redirect from 'https://{my-server.com}/api/v1/export' to 
  'https://res.cloudinary.com/gates/raw/upload/{upload-id}' has been 
  blocked by CORS policy: No 'Access-Control-Allow-Origin' header is 
  present on the requested resource. Origin 'https://{my-frontend.com}' 
  is therefore not allowed access.
  </code></pre>
