How to redirect page in consul?

After seeing this link

I tried to use the same to redirect my page as below.

apiVersion: consul.hashicorp.com/v1alpha1
kind: ServiceRouter
metadata:
  name: frontend-ingress
spec:
  routes:
    - match:
        http:
          pathPrefix: '/frontpage'
      destination:
        service: frontend
    - match:
        http:
          pathPrefix: '/'
      destination:
        prefixRewrite: '/frontpage'
  # NOTE: a default catch-all will send unmatched traffic to "web"

But, it is not working.
If the user types, http://<mainurl> it should redirect to http://<mainurl>/frontpage
Please suggest how to setup this.
