Proxy over redis, HAProxy or twemproxy

haproxyredisreverse-proxy

The best way to hide switching of master/slave redis servers, is to use a proxy over master server.

Among proxy candidates, there is two more important (and used) choices: twemproxy and
haproxy(>=1.5)

If we are not interested of some twemproxy features (like sharding) (and intrested only on proxing job), which one is better (and why?)

If you do not need sharding, haproxy is a good choice.

haproxy is transparent, so you can use all redis command(scan/keys/info ...)

but you may need sharding someday :)

NGINX Reverse Proxy – URL Rewrite

Any redirect to localhost doesn't make sense from a remote system (e.g. client's Web browser). So the rewrite flags permanent (301) or redirect (302) are not usable in your case.

Please try following setup using a transparent rewrite rule:

location  /foo {
  rewrite /foo/(.*) /$1  break;
  proxy_pass         http://localhost:3200;
  proxy_redirect     off;
  proxy_set_header   Host $host;
}

Use curl -i to test your rewrites. A very subtle change to the rule can cause nginx to perform a redirect.

I guess this is what you are looking for, this setup can be easily changed to abstract slave-reads, too.
