45 * Please note: this media handler produces
46 * 3 media files, the raw .mp3, a .m3u which is
47 * contains the URL for the mp3 and a .pls which
48 * contains the URL to the mp3 in shoutcast playlist
49 * format. What's important is that the web server (of
50 * the media host) must recognize the .m3u and .pls file
51 * extensions and send the proper "audio/x-mpegurl"
52 * and "audio/x-scpls" mime-types respectively.
53 * If the web server is apache, it's easy, just
59 * to the file pointed to by the "TypesConfig"
60 * command in your apache config file. Or add
61 * and equivalent AddType command to your httpd.conf.
62 * Of course this assumes that the mod_mime is loaded.
64 * If the web server is not apache, then your on your own.
