func getClient() *http.Client {
  reRouter, _ := reroute.New(http.DefaultTransport, "localhost:1", []string{"localhost:8080"})

  client := &http.Client{Transport: reRouter}

  req, _ := http.NewRequestWithContext(context.Background(), http.MethodGet, "http://localhost:1/foo/bar", http.NoBody)

  res, _ := client.Do(req)

🔭 Plans

• Perhaps add switchover capabilities
• Perhaps add loadbalancer capabilities
• Perhaps improve the markPrimary selection
