Difference between Ciao REST server and Ciao REST connector and when to use each or the other I'm reading the Ciao library and can't make out the difference between Ciao REST server and Ciao REST connector.

When is the connector suitable and at what point do I need the server?

This is a graphic of what im thinking to do:
I don't know about "Ciao" but generally a rest server answers requests from a client that is connecting via a rest connector.
You client will use POST, GET, PUT, etc. to ask the server to provide a service.  This could be as simple as "GET .\index.htm" or more likely posting information to be stored in a database.

The server will sit waiting for these requests and will have handling routines for each specific request and might supply a response.
