My Kubernetes application uses an Ingress to proxy requests to different servers, according to the URL given: I want a fanout configuration. I want the URLs of the requests not to be rewritten when forwarded to the servers. How do I do that?

I want all the /api URLs forwarded to the be service, and all others forwarded to the fe service. But I want the URLs forwarded unchanged. For example

• a request for /api/users should be forwarded to the be service as a request for /api/users.
• a request for /foo should be forwarded to the fe service as a request for /foo.

My current Ingress resource is like this:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  ...
spec:
  ...
  rules:
    - host: ...
    - http:
        paths:
          - path: /api
            backend:
              serviceName: be
              servicePort: 8080
          - path: /
            backend:
              serviceName: fe
              servicePort: 80

but that does not work; it gives 404 Not Found for requests.
