I can't seem to find any information on what TastyPie throttles based on. Is it by the IP of the request, or by the actual Django user object?
Throttle key is based on authentication.get_identifier function.
Default implementation of this function returns a combination of IP address and hostname.
Edit
Other implementations (i.e. BasicAuthentication, ApiKeyAuthentication) returns username of the currently logged user or nouser string.
TastyPie throttling - by user or by IP?
