Hi there,

I’m running two nginx instances in-front of Apache. Trying to pass  
visitors real-ip address to apache.

In normal cases (with one nginx instance in-front of Apache) I’m using:

```
        proxy_set_header X-Forwarded-For 

```

$proxy\_add\_x\_forwarded\_for;

and mod\_rpaf on apache to handle the X-Forwarded-For header.

How do I proceed with two nginx instances where the first one should  
pass $remote\_addr to the second one, which should pass it to Apache?

Thanks!

Boyko

Solved! I was (wrongly) overwriting the x-real-ip and x-forwarded-for  
headers with the second nginx.
