 Routing
 ------------------

 To ensure that the Symfony Router generates urls correctly with Varnish,
 proper ```X-Forwarded``` headers must be added. Headers depend on how you
 have configured hosts and ports for the web server and Varnish but this
 example should work if the web server is using the same IP as Varnish but
 a different port (e.g. 8080).

 .. code-block:: text

    sub vcl_recv {
        if (req.http.X-Forwarded-Proto == "https" ) {
            set req.http.X-Forwarded-Port = "443";
        } else {
            set req.http.X-Forwarded-Port = "80"
        }
    }

 .. note::

    Remember to set ``framework.trust_proxy_headers: true`` in the Symfony
    configuration for this to work.
