Use sendfile to serve users own MEDIA files...

[jedie]

Currently the Django apps serves users MEDIA files by Django's FileResponse...

A better way is that the server used sendfile. A solution is https://pypi.org/project/django-sendfile2/ with a proper server. But Caddy doesn't support this, yet: caddyserver/caddy#3828

In combination with gunicorn we can use OS "sendfile" direct, e.g.:

            file_wrapper = environ.get("wsgi.file_wrapper", FileWrapper)
            return file_wrapper(response.file)
