redis-proxy
===========
The redis-proxy receives requests from clients and separates get and set requests between master and several slaves.
Set commands are always go to master server and get commands go to master or one of slaves(chosen by roundrobin).
AUTH, PING and QUIT commands are processed locally.
After start redis-proxy determines which server is master and set all other servers as slaves.
If master fails the first available slave becomes the master. After server recovery it becomes the slave.
# Build

# Usage
./redis-proxy -[ct] redis-proxy.conf
