Do any of you have suggestions for pulling real time data from a web server into the Arduino?
My use case: Event on desktop client triggers an update of information in a web server. On eventUpdate, the web server (most likely hosted on Windows Azure) can then either display the result on a queried page or can open a socket to push updates to the Arduino.
I need the Arduino to process these updates in as close to real time as possible.
Any suggestions on ways you've used that proved reliable? Right now I'm looking either at a long polling technique or something similar to this implementation (WebSockets).
