by setting `x-amz-storage-class=STANDARD/REDUCED_REDUNDANCY` for each object uploads so effectively utilizing the capacity of the cluster. Additionally these can also be enforced using IAM policies to make sure the client uploads with correct HTTP headers.

- MinIO also supports expansion of existing clusters in server pools. Each pool is a self contained entity with same SLA's (read/write quorum) for each object as original cluster. By using the existing namespace for lookup validation MinIO...

Jeder HTTP-(Fehler-)Statuscode 401 „UNAUTHORIZED“ soll auch einen `WWW-Authenticate`-Header zurückgeben.

Im Fall von Bearer-Tokens (in unserem Fall) sollte der Wert dieses Headers `Bearer` lauten.

Sie können diesen zusätzlichen Header tatsächlich weglassen und es würde trotzdem funktionieren.

Aber er wird hier bereitgestellt, um den Spezifikationen zu entsprechen.

            responseData.setLastModified(statObject.lastModified() == null ? null : Date.from(statObject.lastModified().toInstant()));
            responseData.setMimeType(statObject.contentType());
            statObject.headers().forEach(e -> responseData.addMetaData(e.getFirst(), e.getSecond()));

            if (contentLengthHelper != null) {
                final long maxLength = contentLengthHelper.getMaxLength(responseData.getMimeType());

...y **FastAPI** usa las mismas declaraciones para:

* **Definir requerimientos**: desde request path parameters, query parameters, headers, bodies, dependencies, etc.
* **Convertir datos**: desde el request al tipo requerido.
* **Validar datos**: viniendo de cada request:
    * Generando **errores automáticos** devueltos al cliente cuando los datos son inválidos.

    * Um sich also bei unserer API zu authentifizieren, sendet es einen Header `Authorization` mit dem Wert `Bearer` plus dem Token.
    * Wenn der Token `foobar` enthielte, wäre der Inhalt des `Authorization`-Headers: `Bearer foobar`.
