Redis based IP blacklist for Nginx (LUA)
-- 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.

-- 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
