This checks for media coming in to the MUC (currently just in the form of OOB or SIMS) and then downloads it to a local cache to be served from instead.
This saves privacy leaks for senders (leaking their domains) and to some extent for receivers (who probably trust the MUC more than arbitraty participants in it).
When a message is moderated, any associated media is deleted from the cache.
This does not use Prosody’s internal HTTP server and assumes you will serve the folder of static files somehow.
Files which cannot be cached (due to HTTP errors or limits below) will be passed through still with the original URL unchanged by default.
muc_media_store_path : the path on disk where to store
media files muc_media_public_base : the base URI where you
will serve the media muc_media_max_size : the maximum size
of file to cache
