you disable proxy_redirect and set backend on different port.

http://wiki.nginx.org/NginxHttpProxyModule#proxy_redirect

backend may discover nonstandart port and it may generate 301 redirect including
port number. but if proxy_redirect is off - nginx can not rewrite such redirect.

better approach - configure backend on same port as frontend,
(80 in this case) but on different ip, for example 127.0.0.1,
or, at least, do not disable proxy_redirect.

fragments of my working apache backend config:

========================================================

Listen 127.0.0.1:80

NameVirtualHost *

<VirtualHost *>
    ServerName unknown-apache.example.com
    # ... ^^^ default apache virtual host
</VirtualHost>

<VirtualHost *>
    ServerName virtualhost1.example.com
    # ...
</VirtualHost>

<VirtualHost *>
    ServerName virtualhost2.example.com
    # ...
</VirtualHost>

========================================================

fragments of my corresponding nginx frontend config:

========================================================

http {

    proxy_set_header  Host $host;
    proxy_set_header  X-Real-IP $remote_addr;
    proxy_set_header  X-Nginx-Scheme $scheme;

    server {
        listen 80 default;
        server_name unknown-nginx.example.com;
        # ... ^^^ default nginx virtual host
    }

    server {
        listen 80;
        server_name virtualhost1.example.com;
        # ...
        location / {
            proxy_pass http://127.0.0.1/;
        }
    }

    server {
        listen 80;
        server_name virtualhost2.example.com;
        # ...
        location / {
            proxy_pass http://127.0.0.1/;
        }
    }
}

========================================================

also

   proxy_pass http://127.0.0.1/;

and

   proxy_pass http://127.0.0.1;

are two somewhat different directives for details see
http://wiki.nginx.org/NginxHttpProxyModule#proxy_pass
