### 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

					case !strict && ver.header.matchesNotStrict(latest.header):
						latestCount++
					default:
						latestCount = 1
					}
					latest = ver
					continue
				}

				// Mismatch, but older.
				if latestCount > 0 && !strict && ver.header.matchesNotStrict(latest.header) {
					latestCount++
					continue
				}
				if latestCount > 0 && ver.header.VersionID == latest.header.VersionID {

			withJSON: `{"request":{"uri":"/1","header":{"User-Agent":"test"}}}
{"request":{"uri":"/2","header":{}}}`,

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.
