By default Django REST Framework will try to use the `HTTP_X_FORWARDED_FOR` header to uniquely identify client machines for throttling. If HTTP_X_FORWARDED_FOR is not present `REMOTE_ADDR` header value will be used.
To help Django REST Framework identify unique clients the number of application proxies can be set using `NUM_PROXIES`. This setting will allow the throttle to correctly identify unique requests whenthere are multiple application side proxies in front of the server. `NUM_PROXIES` should be set to an integer. It is important to understand that if you configure `NUM_PROXIES > 0` all clients behind a unique [NAT'd](http://en.wikipedia.org/wiki/Network_address_translation) gateway will be treated as a single client.
