How do you use redis with password?

Hey!

I would really like to use this module but the redis in my environment needs to have authentication turned on.

I tried to solve this by using content_by_lua but don't know how to.

This is what I would want to do but nginx redis or redis2 modules don't support redis passwords:

location /api {
     default_type text/css;

     set $key $uri;
     set_escape_uri $escaped_key $key;

     srcache_fetch GET /redis $key;
     srcache_store PUT /redis2 key=$escaped_key&exptime=120;

     # fastcgi_pass/proxy_pass/drizzle_pass/postgres_pass/echo/etc
 }

 location = /redis {
     internal;

     set_md5 $redis_key $args;
     redis_pass 127.0.0.1:6379;
 }

 location = /redis2 {
     internal;

     set_unescape_uri $exptime $arg_exptime;
     set_unescape_uri $key $arg_key;
     set_md5 $key;

     redis2_query set $key $echo_request_body;
     redis2_query expire $key $exptime;
     redis2_pass 127.0.0.1:6379;
 }

Start with the /redis and /redis2 internal locations in the issue and trace how the redis_pass and redis2_pass flows connect to Redis. Define whether password authentication should be supported in these flows, then verify the result against a password-protected Redis instance; no repository files or tests are named.
