Real-time web applications

In my bachelor work I focus on two servers, which allow us to reach the real-time communication between the client and the server. My main goal is to familiarise PHP application programmers with the real-time communication problems on the internet, to point out differences from typical PHP applications programming and chiefly to focus on practical aspects of this issue. To achieve that, I have structured the dissertation work so that the minimum of the required theory would be explained at first and then I will focus on practical demonstrations, which will be properly commented. My main contribution to this issue is primarily a simple pattern for web pages running in Node.js environment that could be used as an initial point of any kind of web presentation
