Bu header'lar, aksi halde kaybolacak olan orijinal request bilgilerini korur:

* **X-Forwarded-For**: Orijinal client'ın IP adresi
* **X-Forwarded-Proto**: Orijinal protokol (`https`)
* **X-Forwarded-Host**: Orijinal host (`mysuperapp.com`)

**FastAPI CLI** `--forwarded-allow-ips` ile yapılandırıldığında bu header'lara güvenir ve örneğin redirect'lerde doğru URL'leri üretmek için bunları kullanır.

* Güvenli bir bağlantı elde edildikten **sonra**, iletişim protokolü **hâlâ HTTP**’dir.
    * İçerikler, **HTTP protokolü** ile gönderiliyor olsa bile **şifrelenmiştir**.

Ein <abbr title="Ursprung">Origin</abbr> ist die Kombination aus Protokoll (`http`, `https`), Domain (`myapp.com`, `localhost`, `localhost.tiangolo.com`) und Port (`80`, `443`, `8080`).

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“.
