Christoph,
Above application need some kind of reverse proxy to reroute requests based on the type of URLs. SAP Web Dispatcher or Apache can be the entry point for HTTPS requests into your system. SAP Web Dispatcher or Apache selects the appropriate server for HTTPS requests, for example for the OData calls to the ABAP front-end server or SAP HANA XS.
