## An app with callbacks

Let's see all this with an example.

Imagine you develop an app that allows creating invoices.

These invoices will have an `id`, `title` (optional), `customer`, and `total`.

The user of your API (an external developer) will create an invoice in your API with a POST request.

Then your API will (let's imagine):

* Send the invoice to some customer of the external developer.
* Collect the money.

		result := msgPath("service.staging.skydns.local.", path)
		if result != etcdPathSeparator+path+"/local/skydns/staging/service" {
			t.Errorf("Failure to get domain's path with prefix: %s", result)
		}
	}
}

func TestUnPath(t *testing.T) {
	result1 := msgUnPath("/skydns/local/cluster/staging/service/")
	if result1 != "service.staging.cluster.local." {

In particular access to the security-critical production components (root CA, policy, control)
should be locked down and restricted.  The new installer allows multiple instances of
policy/control/telemetry - so testing/staging of new settings and versions can be performed
by a different role than the prod version.

The intended users of this repo are users running Istio in production who want to select, tune
