47 * Please note: this media handler produces
48 * 3 media files, the raw .mp3, a .m3u which is
49 * contains the URL for the mp3 and a .pls which
50 * contains the URL to the mp3 in shoutcast playlist
51 * format. What's important is that the web server (of
52 * the media host) must recognize the .m3u and .pls file
53 * extensions and send the proper "audio/x-mpegurl"
54 * and "audio/x-scpls" mime-types respectively.
55 * If the web server is apache, it's easy, just
61 * to the file pointed to by the "TypesConfig"
62 * command in your apache config file. Or add
63 * and equivalent AddType command to your httpd.conf.
64 * Of course this assumes that the mod_mime is loaded.
66 * If the web server is not apache, then your on your own.
