how to secure downloading mp3 or flv files in nginx

[Kon Wilms]

A PHP script with x-accel-redirect is the best way to implement this -
one internal script to generate content keys, and another to decode
and serve content (handling key verification, time-based expiration,
download counting and download-count based expiration, etc.) via
x-accel-redirect. Download counters are best handled using memcached.
