Before applying the virtualservice, I curl my service via the Ingresgateway...

I apply this virtualservice ...

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: frontend-ingress
spec:
  hosts:
  - "*"
  gateways:
  - frontend-gateway
  http:
  - route:
    - destination:
        host: frontend
        port:
          number: 80
      headers:
        response:
          add:
            hello: world
          remove:
          - "server"
          - "x-envoy-upstream-service-time"
          - "x-envoy-peer-metadata"
          - "x-envoy-peer-metadata-id"

Then curl again - x-envoy-upstream-service-time is removed, others are not.
