force download

some of my users are complaining that when they try download media files (mp3, mpeg, etc) their media player opens and doesn't allow them to physically download the media. These are IE users, firefox seems to like my code, but IE refuses to download the file and plays it instead.. can anyone view my code and see how i can force media file downloads on IE? --snip-- header('Cache-control: max-age=31536000'); header('Expires: ' . gmdate('D, d M Y H:i:s', time() + 31536000) .
