Yes, but that'd require a more complex process on the client. At least you'd have to send an additional request, e.g. instead of just calling https://someserv

Yes, but that'd require a more complex process on the client. At least you'd have to send an additional request, e.g. instead of just calling https://someserviceprovider.com/serviceA https://someserviceprovider.com/serviceA you'd first have to call https://someserviceprovider.com/serviceA https://someserviceprovider.com/serviceA which for example would return { "url": "https://someserviceprovider.com:8081" https://someserviceprovider.com:8081", "auth_token": "..." } and only then could you call the actual service under https://someserviceprovider.com:8081 https://someserviceprovider.com:8081
