-- a quick LUA access script for nginx to check IP addresses against an
-- `ip_blacklist` set in Redis, and if a match is found send a HTTP 403.
--
-- allows for a common blacklist to be shared between a bunch of nginx
-- web servers using a remote redis instance. lookups are cached for a
-- configurable period of time.
--
-- block an ip:
--   redis-cli SADD ip_blacklist 10.1.1.1
-- remove an ip:
