Hi everyone,

I’m using nginx as a reverse proxy for a thttpd server that handles cgi  
scripts.  
Everything works ok, except that the server doesn’t seem to receive any  
visitor info, every IP is interpreted as 127.0.0.1.

This is the config, that I’m using to forward requests:

location ~ .cgi$ {  
proxy\_set\_header X-Real-IP $remote\_addr;  
proxy\_set\_header Host $http\_host;  
proxy\_set\_header X-Forwarded-For $proxy\_add\_x\_forwarded\_for;  
proxy\_pass [http://127.0.0.1:30001](http://127.0.0.1:30001);  
}

sounds like a thttpd config issue 😛

unless thttpd has a way to say that “x-forwarded-for” is the true ip,  
you’re going to have to modify the app to use that IP etc
