centos5.5 + nginx-1.3.14

I use the limit_speed_zone (https://github.com/yaoweibin/nginx_limit_speed_module),and set the nginx.conf:

http {
limit_speed_zone one $server_port 10m;
server {
listen 8080;
server_name localhost;
location / {
root /opt/case/web/www;
index index.html index.htm index.php;
limit_speed one 10k;
}
}
}

The uper setting can limit the speed to 10K per IP.

and then ,i try the HttpLimitConnModule:

http {
limit_conn_zone $server_port zone=addr:10m;
server {
listen 8080;
server_name localhost;
location / {
root /opt/case/web/www;
index index.html index.htm index.php;
limit_rate 20k;
}
}
}

The uper setting can limit the speed to 20K per connetction.and if a IP open 5 thread for conn,then ,the IP can download 100K/s from my nginx.

the nginx.conf of my Nginx with some error?
