Send variables with REST api to Arduino

[jmparatte]

I've checked getDataFromSmartphone.ino example, it works great.

How can we do the same with a REST command http://x.x.x.x:8080/control?... ?
For example, I'm interested to send order to configure/select Arduino experiment, to change source, etc.
Is it possible?
Is there somewhere an example?

Best regards.
