Load balancer question

[Tinte garcia, Miguel Angel]

Hi everyone,
I am starting to work with nginx to use it as a load balancer for a web service. Basically, what I am try to configure is something like:

$  cat nginx.conf
…
http {

           upstream load_balancer {
               server localhost:8080/Instance1;
               server localhost:8080/Instance2;
               server localhost:8080/Instance3;
       }

       server {
               listen 81;
               server_name;
               location / {
                       proxy_pass http://load_balancer;
               }
       }
}
…

I would like nginx to manage the requests among the three instances above, depending on the load. Is it correctly defined? How can I test that my request are properly managed by nginx?
Thanks in advance,

Cheers
