title: Resource interpreted as Document but transferred with MIME type application/octet-stream Console
body: <p>I have a file management system I'm building where only zip files are allowed. I dont want anyone to see where the file is stored on the server so I'm using an ajax call to a php file that executes the following:</p>
  
  <pre><code>if (!empty($find_url)) {
      foreach ($find_url as $file) {
          $dl =  urldecode($file-&gt;file_url);
      }
      $file_headers = @get_headers($dl);
      if($file_headers[0] == 'HTTP/1.1 404 Not Found') {
          $exists = false;
      } else {
  
          $exists = true;
          header('Content-Type: application/zip');
          header("Content-Transfer-Encoding: Binary"); 
          header('Location: '.$dl);
  
      }
  }
  </code></pre>
  
  <p>The file downloads fine but it pumps out a console message pointing out the file location:</p>
  
  <pre><code>Resource interpreted as Document but transferred with MIME type application/octet-stream: 
  "http://www.exmple.co.uk/someplace/filename.zip".
  </code></pre>
