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.
