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