I want users on the site to be able to download files whose paths are obscured so they cannot be directly downloaded.
For instance, I\'d like the URL to be something
S.Lott has the "good"/simple solution, and elo80ka has the "best"/efficient solution. Here is a "better"/middle solution - no server setup, but more efficient for large files than the naive fix:
http://djangosnippets.org/snippets/365/
Basically, Django still handles serving the file but does not load the whole thing into memory at once. This allows your server to (slowly) serve a big file without ramping up the memory usage.
Again, S.Lott's X-SendFile is still better for larger files. But if you can't or don't want to bother with that, then this middle solution will gain you better efficiency without the hassle.
