Usually we use limit_zone module like:
http{

limit_zone one $binary_remote_addr 10m;
server
{
location /mypage{
limit_conn one number_of connections;
}
}

What is the scenario that we should use multiple limit_conn ?

Is there a way to limit total connections to one location ?

E.g. if you want to limit number of connections per ip and total
number of connections per virtual host.

limit_conn_zone $binary_remote_addr zone=perip:10m;
limit_conn_zone $server_name zone=perserver:10m;

server {
    ...
    limit_conn perip 10;
    limit_conn perserver 100;
}

Yes.

Yes.
I’ve just updated documentation with this particular example:

http://nginx.org/en/docs/http/ngx_http_limit_conn_module.html#limit_conn

So if I want to limit total connection to one uri, I can do it by:

limit_conn_zone $host$uri zone=peruri:10m;

server {
    ...
    location / {
        limit_conn peruri 10;
  }

}

but because uri is
