Arduino On-Line

We manage to switch on and off 4 leds in Arduino's plate from a web page.
How it works??
1. A program is loaded in Arduino it receives from Processing “High” or “Low”.
2. From the web page (done in PHP) on a public servidor- anyone-, this servidor communicates with a local servidor installed in my computer, in this case the WampServer (Windows).
3. The local servidor receives a command and send to Processing, this register the command that comes from my own computer IP, that is to say, my "localhost".
4. Finally Processing communicates with Arduino.
