This is the best solution i came up with so far, it allows you to serve downloads from outside of your "/var/www/web/" folder, which makes the file not accessible without running this script used to serve the file.

This way you can check if the downloader has permission to download the file he wants.

In this example i used "/var/www/downloads/" where i store all files i want to serve as a download:

/**
 * http://api.symfony.com/2.2/Symfony/Component/HttpFoundation/BinaryFileResponse.html
 */
use Symfony\Component\HttpFoundation\BinaryFileResponse;

class OfflineToolController extends Controller
{
    /**
     * @return BinaryFileResponse
     */
    public function downloadAction()
    {
        $path = $this->get('kernel')->getRootDir(). "/../downloads/"; 
        $file = $path.'my_file.zip'; // Path to the file on the server
        $response = new BinaryFileResponse($file);

        // Give the file a name:
        $response->setContentDisposition(ResponseHeaderBag::DISPOSITION_ATTACHMENT,'my_file_name.zip');

        return $response;
    }

}
