## Forwarding to ExternalNames
When specifying an [ExternalName](https://kubernetes.io/docs/concepts/services-networking/service/#services-without-selectors),
Træfik will forward requests to the given host accordingly and use HTTPS when the Service port matches 443. This still requires setting up a proper port mapping on the Service from the Ingress port to the (external) Service port.
## Disable passing the Host header
By default Træfik will pass the incoming Host header on to the upstream resource.
