I found that the native Safari HTML5 Player(suppose it is AVPlayer under the hood), adds X-Playback-Session-Id header for each master/media playlists and chunks requests.
Unfortunately, I can't find any official documentation or spec on this topic.
I am just curious about what is this header about and how it is computed?
Because of the lack of documentation on this:
Is it a stable one?
Can We rely on this header in production?
