POSTing to an Apache Server

This works. I had to test it first.

  client.println("POST /arduino.php HTTP/1.0");
  client.println("Content-Type: application/x-www-form-urlencoded");
  // the Content-Length must be set to the number of characters after the double CR/LF
  client.println("Content-Length: 9\r\n");
  client.print("testone=1");
