The idea is that this rewrite is handled "externally" by the client, not by Istio.

Practical examples

HTTP to HTTPS redirect.

The following Virtual Service configuration will redirect all the incoming traffic from the gateway my-gateway that uses the http protocol, to the https protocol.

In this example, it would forward all the http traffic without taking into account which port is used.

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: to-https-vs
spec:
  hosts:
    - "*"
  gateways:
    - my-gateway
  http:
  - match:
    - name: to_https
      match:
        scheme: http
      redirect:
        scheme: https

Migrated from a domain

The following will update the requests coming "to" the domain old.domain.com and rewrite the URL to use the "new" new.domain.com

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: update-domain-vs
spec:
  hosts:
    - "old.domain.com"
  gateways:
    - helloworld-gateway
  http:
    - name: forward-to-new-domain
      redirect:
        authority: "new.domain.com"
