                    ngx.log(ngx.ERR, "req data:", req_data)
                    tcp_req:send(req_data)
                end
            ';
        }
    }

Pay attention

Its not a pure nginx tcp server. But is more power if you use ngx-lua with this way. It have great compatibility, and you can use 100% api of nginx-lua-module with lastest version.
