  A simple web server that lets you blink an LED via the web.
  This sketch will print the IP address of your WiFi Shield (once connected)
  to the Serial monitor. From there, you can open that address in a web browser
  to turn on and off the LED on pin 9.

  If the IP address of your shield is yourAddress:
  http://yourAddress/H turns the LED on
  http://yourAddress/L turns it off
