Cookieless stickyness with subsets

Networking
1

Hi felas,

I am currently struggeling to apply a cookieless stickyness to our deployment with subsets.
The situation is as follows :

Virtual Service

The goal is , that the user keeps the Version which he was assigned to as long as his session remains.
This should apply even during / after a traffic shift.
We achieved this by setting cookies upon initial request. We had to do this, since it looked like the stickyness which applied in the Destination Rule did not apply while using weight based connections.

http:
  # match for existing prod frontend sessions
    - match:
      - uri:
          prefix: /test.html
        headers:
          Cookie:
            regex: ^(.*;?)?(frontend_version=prod)(;.*)?
      - destination:
          host: frontend
          port:
            number: 80
          subset: prod
  # match for existing staging frontend sessions
    - match:
      - uri:
          prefix: /test.html
        headers:
          Cookie:
            regex: ^(.*;?)?(frontend_version=staging)(;.*)?
      - destination:
          host: frontend
          port:
            number: 80
          subset: staging
  # initial match for prod/staging frontend
    - match:
      - uri:
          prefix: /test.html
      - destination:
          host: frontend
          port:
            number: 80
          subset: prod
        weight: 0
        headers:
          response:
            add:
              "Set-Cookie": frontend_version=prod; Path=/
      - destination:
          host: frontend
          port:
            number: 80
          subset: staging
        weight: 100
        headers:
          response:
            add:
              "Set-Cookie": frontend_version=staging; Path=/

Destination Rule

apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
  name: frontend-destrule
spec:
  host: frontend
  subsets:
  - labels:
      app.kubernetes.io/version: prod
    name: prod
  - labels:
      app.kubernetes.io/version: staging
    name: staging
  trafficPolicy:
    loadBalancer:
      consistentHash:
        # httpCookie:
        #   name: route_frontend
        #   path: / 
        #   ttl: 0s
       useSourceIp: true

Is there any option to do this without cookies ?
