On this video you would be able to learn how the server application works and interacts with the client's request. If you intend to start your own web application written in C++ then you are in the right track, this would be your starting point to learn C++ from simple coding into complex.
You can add more features as you wish, customize and extend functionalities.One piece is missing from the video is the headers implementation which I think it is included once it is downloaded.
If you cannot play the video please click [Youtube: Implementing Web Server Application using C++]
