## By default this config uses default local driver,

So, all these are different origins:

* `http://localhost`
* `https://localhost`
* `http://localhost:8080`

Even if they are all in `localhost`, they use different protocols or ports, so, they are different "origins".

## Steps { #steps }

Alle folgenden sind also unterschiedliche Origins:

* `http://localhost`
* `https://localhost`
* `http://localhost:8080`

Auch wenn sie alle in `localhost` sind, verwenden sie unterschiedliche Protokolle oder Ports, daher sind sie unterschiedliche „Origins“.

Wenn Sie mit **mehreren Prozessen** dasselbe API-Programm ausführen, werden diese üblicherweise als <abbr title="Arbeiter">**Worker**</abbr> bezeichnet.

### Workerprozesse und Ports { #worker-processes-and-ports }

Erinnern Sie sich aus der Dokumentation [Über HTTPS](https.md){.internal-link target=_blank}, dass nur ein Prozess auf einer Kombination aus Port und IP-Adresse auf einem Server lauschen kann?

When you run **multiple processes** of the same API program, they are commonly called **workers**.

### Worker Processes and Ports { #worker-processes-and-ports }

Remember from the docs [About HTTPS](https.md){.internal-link target=_blank} that only one process can be listening on one combination of port and IP address in a server?

This is still true.
