+
+## 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`
+
+```yaml
+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"
+```
