Upstream setup with proxy and fastcgi?

[TECK]

Ok, some updates on the testing. Using the configuration listed below
does allow me to display index.php, but not index.html:
http {
...
	upstream backend {
		server			192.168.0.2:8000;
		server			192.168.0.3:8000;
		server			192.168.0.4:8000;
	}

	upstream fastcgi {
		server			192.168.0.2:9000;
		server			192.168.0.3:9000;
		server			192.168.0.4:9000;
	}
...
}

server {
	listen				publicip:80 default_server backlog=256 rcvbuf=32k sndbuf=8k;
	server_name		domain.com;
	root				/var/www/html;
	index				index.php index.html;

	location / {
		proxy_pass		http://backend;
	}

	location ~ \.php$ {
		fastcgi_pass		fastcgi;
		include			fastcgi.conf;
	}
}

I tried to use only one server as main entrance but the load is going
very high, once I run siege on it.
How would I enable support for regular html files in the above
configuration?

Thanks.
