* Siehe: https://github.com/linkedin/cruise-control-ui/wiki/CORS-Method
* Die Zugriffe werden weiter abgelehnt.
* _Grund:_ Die Vorgaben erlauben nur einen speziellen Header.
* Die Anfragen werden dann wegen Headern wie z.B. `Content-Type` abgelehnt.
* *Idee:* UI in das CC-Image einbauen - _müsste laut Parametern gehen!_
