// A cross-domain policy file is an XML document that grants a web client, such as Adobe Flash Player
// or Adobe Acrobat (though not necessarily limited to these), permission to handle data across domains.

Die folgenden Argumente werden unterstützt:

* `allowed_hosts` – Eine Liste von Domain-Namen, die als Hostnamen zulässig sein sollten. Wildcard-Domains wie `*.example.com` werden unterstützt, um Subdomains zu matchen. Um jeden Hostnamen zu erlauben, verwenden Sie entweder `allowed_hosts=["*"]` oder lassen Sie diese Middleware weg.

func getResource(path string, host string, domains []string) (string, error) {
	if len(domains) == 0 {
		return path, nil
	}

	// If virtual-host-style is enabled construct the "resource" properly.
	xhost, err := xnet.ParseHost(host)
	if err != nil {
		return "", err
	}

	for _, domain := range domains {
		if xhost.Name == minioReservedBucket+"."+domain {
			continue
		}

* **TCP weiß nichts über „<abbr title="Domäne, Bereich, Wirkungsraum">Domains</abbr>“**. Nur über IP-Adressen.
    * Die Informationen über die angeforderte **spezifische Domain** befinden sich in den **HTTP-Daten**.
* Die **HTTPS-Zertifikate** „zertifizieren“ eine **bestimmte Domain**, aber das Protokoll und die Verschlüsselung erfolgen auf TCP-Ebene, **ohne zu wissen**, um welche Domain es sich handelt.

```JSON
{
  "detail": "Item not found"
}
```

!!! tip
    When raising an `HTTPException`, you can pass any value that can be converted to JSON as the parameter `detail`, not only `str`.

    You could pass a `dict`, a `list`, etc.

    They are handled automatically by **FastAPI** and converted to JSON.
