Comment (by kelexel):

 Confirmed.

 If you add #EXT-X-ALLOW-CACHE:0 in the top of the playlist, it (as long as
 mpegts files) are not cached by the client.

 So if broadcaster drops, and ffmpeg transcoding stops, and broadcaster
 comes back, and ffmpeg transcoding is restarted, hitting refresh on the
 clients will fetch a fresh playlist instead of the locally cached one.

 May I suggest a -segment_no_cache setting that would append #EXT-X-ALLOW-
 CACHE:0 to the top of the playlist ?
