Use client.println() to print data followed by a carriage return and newline.
https://www.arduino.cc/en/Reference/WiFiClientPrintln
Use client.available() to return the number of bytes available for reading.
https://www.arduino.cc/en/Reference/WiFiClientAvailable
Use client.read() to read the next byte received from the server the client is connected to.
