| Host | X-Forwarded-Host |
| Port | X-Forwarded-Port |

#### ServersTransport reference
By default, the referenced ServersTransport CRD must be defined in the same [Kubernetes service](https://kubernetes.io/docs/concepts/services-networking/service/) namespace.
To reference a ServersTransport CRD from another namespace,
the value must be of form `namespace-name@kubernetescrd`,
and the [cross-namespace](../../../providers/kubernetes-crd/#allowcrossnamespace) option must be enabled.
If the ServersTransport CRD is defined in another provider the cross-provider format `name@provider` should be used.
