If you're in the situation that you have an authenticated Django view that returns files for download, you may have noticed that Safari 9.x doesn't play audio files properly when returning audio-files. The reason is that Safari sends a HTTP_RANGE request header and expects a proper Content-Range response header in return. The original suggested fix applies the code to Django's static view. This is a packaged version of that fix, but uses a modified FileResponse, instead of applying it to Django's static view.
