i am trying to move from nginx-\>fastcgi to nginx-\>apache-\>fastcgi

this how i have configured proxy\_pass to my apache running on 2080.  
my app gets the client ip address as 127.0.0.1. how to make it see the  
correct real ip address.

```
    location / {
        root /home/live/work/apps;
        proxy_pass http://127.0.0.1:2080/$host$request_uri;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_set_header IP_GEO $geo;
    }

```

i get the server address as this ‘SERVER\_ADDR’: ‘127.0.0.1’, how to fix  
this?

the IP\_GEO header gets converted to HTTP\_IP\_GEO, is there anyway to  
avoid  
this as my python app uses IP\_GEO everywhere.

thanks a lot!

You should use mod\_realip/mod\_rpaf2 on Apache side.

Again, you should handle this on Apache side. nginx just passes  
headers with information, nothing more.
