* Wenn PathInfo nicht gesetzt ist, landet man immer in diesem Controller und es sieht so aus
|

* als würde die API grundsätzlich funktionieren, obwohl man im falschen Endpunkt rauskommt.

* Lösung:
|
|
* Nachfolgend wird versucht den PathInfo-Teil aus anderen Server-Variablen zu ermitteln.
|
|
* Bei Unterschieden zwischen dem ermittelten und dem gesetzten PathInfo wird eine Exception geworfen.
