Well think about how you would do this using a shell script, combined
with curl, inotify, etc.
Then take the same principles/flows and translate that into lua.

One thought is this.. when ATS receives a request for a m3u8, and if
that m3u8 results in a 200 TCP_MISS, then store that m3u8 URL
somewhere.
When that m3u8 is stored in whatever location, that store triggers a
job that then parses the m3u8, and then requests(using curl or
whatever http client) x amount of media segments from that m3u8.
By the time the client request those same segments, they are already
stored in cache.
