This server allows you to establish communication between web applications living in a browser
and enables backend scripts, in my case PHP, to communicate information back to web applications that have called the backend script to perform some action.
Clients receive a UUID from the server upon connection. If the web application triggers
backend scripts via AJAX it passes the UUID to the backend scripts. The script is now able to report
back to the web client by sending the UUID along with an opcode 'feedback' and other parameters to the server.
With the given UUID the server now knows to what web client to send the message. Loop closed !
