Kong behind CDN

[omegion]

Hi,

I am running Kong in my Kubernetes cluster behind a service and a CDN. I have an HTTPRoute with a hostname:

apiVersion: gateway.networking.k8s.io/v1
kind: HTTPRoute
metadata:
  name: service-a
spec:
  parentRefs:
    - name: internal
      namespace: gateway-api
  hostnames:
    - service-a.private-domain
  rules:
    - matches:
        - path:
            type: PathPrefix
            value: /
      backendRefs:
        - name: deployment
          port: 80

The problem is that I accept traffic to service-a.example.com public domain, but my internal hostname is service-a.private-domain, but Kong gets the Host header as service-a.example.com and does not match any route.

How can I ignore the Host header of my CDN?

Hi @omegion , you can try using the request-transformer plugin to achieve your goal. Please refer to the documentation for more details. https://docs.konghq.com/hub/kong-inc/request-transformer/how-to/#example-adding-a-querystring-and-a-header
