-- a quick LUA access script for nginx to check IP addresses match an
-- `ip_whitelist` set in Redis, and if no match is found send a HTTP
-- 403 response or just a custom json instead.
--
-- allows for a common whitelist to be shared between a bunch of nginx
-- web servers using a remote redis instance. lookups are cached for a
-- configurable period of time.
--
-- white an ip:
--   redis-cli SADD ip_whitelist 10.1.1.1
