Hi,

I need to alias a subdomain to contents of an url, e.g. I need  
[http://abcd.domain.com/](http://abcd.domain.com/) to proxy contents of  
[http://www.domain.com/path1/path2/xyz](http://www.domain.com/path1/path2/xyz)

All my attempts with proxy\_pass resulted in 301 to  
[http://abcd.domain.com/path1/path2/xyz](http://abcd.domain.com/path1/path2/xyz) and a 404 with strange duplicate  
uri /path1/path2/xyzpath1/path2/xyz

```
    server {
            listen 11.22.33.44:80;
            server_name abcd.domain.com;

            location / {
                    proxy_pass 

```

[http://www.domain.com/path1/path2/xyz](http://www.domain.com/path1/path2/xyz);  
}  
}

I’m clearly missing something, please help!

Hi,

I think what you might need to set is ‘proxy\_redirect’. I’m running a  
similar setup which works this way.

Hi Chris,

I was missing $1 in the end of the uri so the rewrite works.  
Without it, it was being silently ignored and was creating a redirect  
loop.

For the mailing list archival purposes, here is what I ended up with:

```
    server {
            listen 11.22.33.44:80;
            server_name abcd.domain.com;

            location / {
                    rewrite ^(.*)$ /path1/path2/filename$1 break;
                    proxy_pass http://www.domain.com;
            }
            server_tokens off;
    }

```

Thanks again,  
Vahan

proxy\_pass [http://www.domain.com/path1/path2/xyz/](http://www.domain.com/path1/path2/xyz/);  
slash (“/”) in the end.

This works without rewrites:

```
location / {
     proxy_pass http://www.domain.com/path1/path2/filename/;
}

```

Damn, sometimes a single trailing slash can be a show-stopper 🙂
