Routing

To ensure 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 different port (e.g. 8080).
