R/W splitting. All requests only to write server.

[Pavel Scherbakov]

I have mysql-proxy-0.6.1.

Start script:

#!/bin/bash

MASTERDB=10.0.87.138
SLAVEDB01=10.0.87.223
SLAVEDB02=10.0.87.163
ROOT_DIR=/usr

LUA_PATH="$ROOT_DIR/share/mysql-proxy/?.lua" $ROOT_DIR/sbin/mysql-proxy \
--daemon \
--proxy-backend-addresses=$MASTERDB:3306 \
--proxy-read-only-backend-addresses=$SLAVEDB01:3306 \
--proxy-read-only-backend-addresses=$SLAVEDB02:3306 \
--proxy-read-only-backend-addresses=$SLAVEDB03:3306 \
--proxy-lua-script=$ROOT_DIR/share/mysql-proxy/rw-splitting.lua

When I connect to port 4040, all my requests go only to one host - 10.0.87.138.
Why SELECT request don't go to slave DB?
