+Your application has access to the HTTP headers `X-Forwarded-Proto`, `X-Forwarded-Port` and `X-Forwarded-For`. These headers indicate the protocol of the original request (HTTP or HTTPS), the port number, and the IP address of the client making the request, respectively. The default configuration is for Nginx to set these headers.
 
 If your server runs behind an HTTP/S load balancer, then Nginx will see all requests as coming from the load balancer. If your load balancer sets the `X-Forwarded-` headers, you can tell Nginx to pass these headers from load balancer to your application by using the following [nginx custom template](/dokku/configuration/nginx/#customizing-the-nginx-configuration)
