I've been following this thread not really out of need but rather that it is really interesting. That said, I don't think for security you want to "escape" the web root. The risk is that might aid a traversal attack.

You could place the different versions away from the root so they cannot
be obtained from the web. Then they can be served by setting up a
symlink to the desired version.

This can be changed using "ln -sfn version/dir serving/root" and then
restarting nginx to pick up the new version.

By not using redirects, this method should be more efficient.

Regards

Ian
