Hello Group,

I’ve got my Rails app deployed as a Mongrel cluster behind an Nginx  
reverse proxy. It’s working great except for one small issue: if I  
have code that does a redirect\_to , the browser is  
redirecting to [http://mongrel](http://mongrel). What I’d like to have it direct to is  
“http:///”. Does that make sense?

Here’s my Nginx config file:

```
upstream mongrel {
    server 127.0.0.1:9000;
    server 127.0.0.1:9001;
    server 127.0.0.1:9002;
}

```

```
server {
    listen 80;
    server_name <my domain name>;
    root <my deployment path>;

```

```
    location / {
        proxy_pass http://mongrel;
        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;  
}
