Is your feature request related to a problem? Please describe.
A CDN is not a part of the project, but we need to show the value of the project, teaching how to incorporate the streams into a CDN/web server.

Describe the solution you'd like

• A request like /live/123 is made to this example web server
• This webserver queries Redis to know which playout server holds 123 stream
• It pulls the content and delivers to the client that requests /live/123

Describe alternatives you've considered

• NGINX is a good choice because it is pretty famous and many streaming platforms run behind NGINX web servers
• A simple Go HTTP server also does the job by requesting the server holding the streaming
