Maybe my blog count? ;)


I do have the plan of writing a bunch of (detailed) tutorials on this this year.

The ngx_redis2 module returns the raw TCP response from the redis
server. It's recommended to use my lua-redis-parser module (written in
pure C) to parse these responses into lua data structure:


If you only want to use the "get" redis command, you can try out the
ngx_redis module here:


It returns the parsed content part of the redis response because only
"get" is needed to implement.

Right, using ngx_srcache + ngx_lua + lua-redis-parser. See ngx_srcache
for details:


It's much like Apache2's mod_cache, but only support silly response
body caching (for now) and is 100% non-blocking. I're already using
ngx_srcache + ngx_memc to cache responses via memcached in production.
