Playlist update?

[pahenning]

I am one of the developers of the German home automation software FHEM (see http://www.fhem.de, 20.000 registered users in the forum). We have a nice module in the beta stadium that creates playlists in the m3u format, and writes them to the MinimServer music directory.

Adding a file to the playlist by pressing a button on a wall mounted tablet then of course re-writes the playlist file. However, an audio system accessing the MinimServer does not get the new playlist, because the old file is apparently cached by the MinimServer.

With other music servers (like miniDLNA) one may use a trick, e.g. by first deleting the old playlist file and then adding a new one. This does _not_ work with MinimServer.

Question therefore: is there a similar trick to get the MinimServer to read a new playlist file?

Regards
