Thanks for your reply and the detailed information. Your solution looks great, and I guess that using a web server-based solution (in contrast to a Django-based one) is much more efficient. What I do not understand in your setup is why, if you have HttpUploadProgressModule installed, you do need a custom upload handler and AJAX view? IIUC HttpUploadProgressModule is providing this for free, isn't it?
Unfortunately, my hoster is not using nginx but Apache. Maybe there is a Django-compatible module for it out there; https://github.com/drogus/apache-upload-progress-module/ seems to be an option but I haven't tried it yet.
