i found config from: Nginx location+proxy_pass? - NGINX - Ruby-Forum

my nginx version: 0.6.13
and here is my full working nginx.conf:

user www;
worker_processes 1;

events {
worker_connections 1024;
}

http {

include mime.types;

upstream mongrel_cluster1 {
server 127.0.0.1:3001;
server 127.0.0.1:3002;
}

upstream mongrel_cluster2 {
server 127.0.0.1:4001;
server 127.0.0.1:4002;
}

server {
listen 127.0.0.1:80 default deferred;

location /app1/ {
    proxy_pass http://mongrel_cluster1/;
}

location /app2/ {
    proxy_pass http://mongrel_cluster2/;
}

}

}

his config file works find in Rails 1.2.x, but not work for Rails
2.1. do you know how to make it works for Rails 2.1?
