Secure Downloads

I need to create a site which has downloadable files in a library. The
site will be accessed via username/password login done in the Rails app.
However, I need the actual downloadable files to be protected as well.

I'll be running the rails app on a mongrel cluster.

I've looked at using lighttpd as the web/proxy server and the
mod_secdownload module which looks nice. However, I'd rather *not* use
lighttpd is possible.

Ideally, I'd like to use Apache or nginx as the web/proxy server but the
lack a similar mod_secdownload module.

Does anybody have any recommendation on how to achieve protected
downloads without lighttpd or reverting to long random URLs (which is
not that secure).

Thanks,

~ Mark

You can use X-Sendfile with Apache to do this. The apache module is
here: http://tn123.ath.cx/mod_xsendfile/

There's a plugin to handle the Rails side at http://john.guen.in/rdoc/x_send_file/

With this approach, your Rails app handles the authentication, and
then Apache sends the file when Rails has said it is ok to do so.

Many thanks Michael. I ended up using nginx's 'X-Accel-Redirect' feature
which is basically the same thing as Apache's x-sendfile. Perfect!
