How to understand what request gives a view on the counter?

Question

Computer networks

On the twitch.tv site, I can’t understand how the view is added when you go to one of the streams.
That is, there is streaming video, m3u .ts arrive every couple of seconds
(unfortunately, I’m still far from strong in broadcasting stream, I don’t even know which tags to put on the question), maybe this is the flag that increases the stream counter, that is, I need to send requests somehow every time?
Someone may already be familiar with similar systems.

Answer 1

without observation and feedback - in no way
can he count immediately, but to show that he added / counted not immediately
look for it experimentally
