You may want to actually read the link provided.  It explains how 
to configure limit_conn, what it does and what will be the 
expected result.  Quoting most relevant part of the limit_conn 
directive docs (http://nginx.org/r/limit_conn):

: Sets the shared memory zone and the maximum allowed number of 
: connections for a given key value. When this limit is exceeded, 
: the server will return the 503 (Service Temporarily Unavailable) 
: error in reply to a request. For example, the directives
: 
: limit_conn_zone $binary_remote_addr zone=addr:10m;
: 
: server {
:     location /download/ {
:         limit_conn addr 1;
:     }
: 
: allow only one connection per an IP address at a time.
