This is an Nginx upstream module that makes nginx talk to a redis 2.x server in a non-blocking way. It has a similar interface with the standard ngx_memcached module, but only Redis
SELECT commands are supported.
This module returns the decoded result from the Redis server.
This module is written by Sergey A. Osokin.
This module is enabled by default and can be disabled by passing the
--without-http_redis_module option to the
./configure script for OpenResty.
