 The path of each route being loaded from the new routing resource will now
 be prefixed with the string ``/site``.

 Prefixing the Names of Imported Routes
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 .. versionadded:: 3.4
    The feature to prefix route names was introduced in Symfony 3.4.

 You also have the possibility to prefix all route names defined in a controller
 class with the ``name`` attribute of the ``@Route`` annotation::

    use Symfony\Component\Routing\Annotation\Route;

    /**
     * @Route(name="blog_")
     */
    class BlogController extends Controller
    {
        /**
         * @Route("/blog", name="index")
         */
        public function indexAction()
        {
            // ...
        }

        /**
         * @Route("/blog/posts/{slug}", name="post")
         */
        public function showAction(Post $post)
        {
            // ...
        }
    }

 In this example, the names of the routes will be ``blog_index`` and ``blog_post``.
