Hi,
What will be the end URL, consider a scenario where you would like to SUP 2.1 with relay server. and at the other end you will netweaver gateway which is connected to SUP
SAP <--->NWGW<-> SUP 2.1<-----> iOS/Android
> Relay server <
in this kind of connection what will be the URL for metadata or service doc, which I can mention in the code.
