So I of course know that serving static files through Django will send you straight to hell but I am confused on how to use a custom url to mask the true location of the file using Django. http://stackoverflow.com/questions/2681338/django-serving-a-download-in-a-generic-view but the answer I accepted seems to be the "wrong" way of doing things.

urls.py:

url(r'^song/(?P<song_id>\d+)/download/$', song_download, name='song_download'),

views.py:

def song_download(request, song_id):
    song = Song.objects.get(id=song_id)
    fsock = open(os.path.join(song.path, song.filename))

    response = HttpResponse(fsock, mimetype='audio/mpeg')
    response['Content-Disposition'] = "attachment; filename=%s - %s.mp3" % (song.artist, song.title)

    return response

This solution works perfectly but not perfectly enough it turns out. How can I avoid having a direct link to the mp3 while still serving through nginx/apache?

EDIT 1 - ADDITIONAL INFO

Currently I can get my files by using an address such as: http://www.example.com/music/song/1692/download/ But the above mentioned method is the devil's work.

How can I accomplished what I get above while still making nginx/apache serve the media? Is this something that should be done at the webserver level? Some crazy mod_rewrite?
