Upstream doesn't rewrite the host name?

This example from the documentation does not work for me:

http {
upstream myproject {
server 127.0.0.1:8000 weight=3;
server 127.0.0.1:8001;
server 127.0.0.1:8002;
server 127.0.0.1:8003;
}

server {
    listen 80;
    server_name www.domain.com;
    location / {
        proxy_pass http://myproject;
    }
}

}

In Firefox nginx is returning URLs like: http://myproject/
There seems to be a step missing that converts myproject into the
server_name

I’ve tried the latest 0.7.26 and an earlier ubuntu (0.5.33-1). Both
behave this way.

I’m new at nginx and I’m sure it’s my fault. I’m just not seeing it.
Any help would be appreciated.

Thanks.

Ok, after quite a bit of searching and reading I found I needed
something like this:

location = / {
    proxy_pass http://tomcatcluster;
    proxy_redirect off;
    proxy_set_header Host $host ;
    proxy_set_header X-Real-IP $remote_addr ;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for ;
}

From a newb perspective, the documentation should have contained an
example like this.

nginx looks amazing.

Yeah I think that is a common point of confusion. You have to pass
along some of the headers explicitly you want, and one of the most
important is Host.

The X-Real-IP and X-Forwarded-For may be redundant, depending on your
application and how it uses it.
