### Set object lock

PutObject API allows setting per object retention mode and retention duration using `x-amz-object-lock-mode` and `x-amz-object-lock-retain-until-date` headers. This takes precedence over any bucket object lock configuration w.r.t retention.

```sh

///

Zuerst erstellen wir eine `GzipRequest`-Klasse, welche die Methode `Request.body()` überschreibt, um den Body bei Vorhandensein eines entsprechenden Headers zu dekomprimieren.

Wenn der Header kein `gzip` enthält, wird nicht versucht, den Body zu dekomprimieren.

Auf diese Weise kann dieselbe Routenklasse gzip-komprimierte oder unkomprimierte Requests verarbeiten.
