Web Service to Web Service Connectivity

Hi there,

My scenario is as follows:

Client (Windows 8.1 App) <- WEB SERVER with WCF Web Service <- RESTFul Web Service <- Database

How do I talk from the IIS web service, to ANOTHER RESTful Web service? My database (InterSystems Cache) is hosting a RESTful web service, but I don't want to go from client to database, I want to go through a web server first, then to the database and back again. It is all JSON data being used.

I'm new to RESTful web services, I've only used WCF SOAP-based services, so the idea of resource URIs is new to me. I'm just a little confused about how I actually go and CREATE the resources for the WCF web service.

Finally, is the best way to add an ASP.NET web application to my solution? And create the WCF service from there? I have some server-side data layers to create as well.

Regards,

Mike
