I am trying to run a data server behind nginx by using a reverse proxy.  
My problem is that the host name received by my application contains the  
port of the proxied server not the port of the initial request i.e. a  
request to [http://myserver/dataserver](http://myserver/dataserver) is forwarded to /dataserver:30084  
but my appliaction gets myserver:30084 instead of myserver. It is a  
requirement that I know the port of the original request so as to be  
able to operate on a port other than 80. As it stands I am having to  
programatically remove the port.

This is part of my nginx.conf:

```
server {
    listen 80;
    server_name localhost;

    location / {
        root html;
        index example.html example.htm;
    }

    location /dataserver {
        proxy_pass http://localhost:30084/dataserver;
        proxy_set_header Host $host;
    }

```

Any help would be appreciated.

My bad. I didn’t have correct “proxy\_set\_header” settings.
