Secure static media access in a Django site

I'm building a site where registered users can upload files. Those files are then served via Apache. Only users who are logged in should be able to access those files.

I have read this page but it seems that people would have to log in twice to access both the site and the media, each time using a different type of login box.

Is there a way around this or is there some other way to limit access to static media served by Apache using the Django authentication database?

I'm using mod_python.

EDIT: How I ended up solving this after reading Van Gale's answer and this:

  1. Switched to WSGI.
  2. Installed mod_xsendfile
  3. Moved all public media files into a subfolder in /media/public
  4. Added access to the public folder using an Alias /media/public /var/www.../media/public
  5. Added WSGIScriptAlias /media/protected/ /var/www.../apache/django.wsgi (same handler as for the rest of the site)
  6. Added XSendFile On and XSendFileAllowAbove On
  7. To the Django app I added an urlconf for /media/protected which does basically what's here, only modified for my authentication system. It handles urls such as /media/protected/GROUP_ID/file so that only members of the GROUP can download the files.

The usual way to do this is to pass back a special header to the web server.

You can do it with nginx using x-accel-redirect as in this Django snippet.

For Apache, it should be pretty similar using the mod_xsendfile module (discussion and examples on Django users mailing list).

If you have freedom to switch from Apache to lighttpd, then the most straightforward solution would be to use mod_secdownload which would do exactly what you want, that is, provide application authentication while serving the actual files via web server.

However if you are stuck with Apache, then I suggest mod_auth_token, here they mention PHP but you can generate the token in Python or any other language. Using mod_auth_token you will be able to generate the token in your application, and then have web server serve the static file utilizing that token.
