Chat room implemented using
|

<a href="http://sourceforge.net/projects/civetweb/" target="_blank">Civetweb</a>
|
||||
embeddable web server.
|
||||
This application was written for educational purposes demonstrating
|
||||
how web interface could be decoupled from the business logic. Not a
|
||||
single line of HTML is generated by the server, instead, server
|
||||
gives data to the client in JSON format.

Simple demo of WebSocket connection use. Not a great example of web coding,
|

but it is functional.
