i wrote all geoip database in geo.conf, and i wrote these lines in http  
segment.  
geo $geo {  
include geo.conf;  
}

and I set upstream in http segment like:  
upstream default {  
server [folderfile.net](http://folderfile.net);  
}

upstream kr {  
server [nixneo.com](http://nixneo.com);  
}

and added server segment and set proxy\_pass.  
server {  
listen 80;  
server\_name [geotest.folderfile.net](http://geotest.folderfile.net);

location / {  
proxy\_pass http://$geo;  
}

work looks fine, request in korea perfectly proxied to [nixneo.com](http://nixneo.com) and  
other requests go to [folderfile.net](http://folderfile.net) BUT! the problem appeared.  
you can see the problem in this url :  
[http://geotest.folderfile.net/index.php?mid=talkboard](http://geotest.folderfile.net/index.php?mid=talkboard) (original  
url:[http://delphixe.folderfile.net/index.php?mid=talkboard](http://delphixe.folderfile.net/index.php?mid=talkboard))  
can’t see the problem? let you explain it.

I can’t get to [folderfile.net](http://folderfile.net), so I can’t test this directly.

I _think_ this says “the proxied server creates links to its local  
resources using http:// and whatever the client sent in the Host:  
header”.

You can try adding

proxy\_set\_header Host $host;

> location / {  
> proxy\_pass http://$geo;  
> }

inside that location, so that the Host: header used will probably be  
resolvable by the client.

Good luck with it,

I tried that, and I get 500 Internal Server Error.  
and more lines what I tested :  
proxy\_set\_header X-Real-IP $remote\_addr;  
proxy\_set\_header X-Forwarded-For $proxy\_add\_x\_forwarded\_for;

in any case, dosen’t worked.

temporarily, I solved problem.  
upstream [default.folderfile.net](http://default.folderfile.net) {  
server [folderfile.net](http://folderfile.net);  
}  
upstream [kr.folderfile.net](http://kr.folderfile.net) {  
server [nixneo.com](http://nixneo.com);  
}

location / {  
proxy\_pass http://$geo.folderfile.net;  
}

and I added record for [default.folderfile.net](http://default.folderfile.net) → [folderfile.net](http://folderfile.net)’s server  
IP & [kr.folderfile.net](http://kr.folderfile.net) → [nixneo.com](http://nixneo.com)’s IP  
so, that image appeared, the link was :  
[http://default.folderfile.net/modules/document/tpl/icons/file.gif](http://default.folderfile.net/modules/document/tpl/icons/file.gif)

but… It is incomplete solution.

- now, you can see that site. I opened my server.

Hi there,

you’ve found something that works for you, so you can stay with that  
configuration.

However:

I find that it is usually worth understanding _why_ configurations fail,  
so it might be worth investigating happened there.

They can be useful if the proxied server is configured to care about  
them.

Perhaps [nixneo.com](http://nixneo.com) responds differently based on the source address; but  
from where I am, it looks like you have a redirector, not a reverse  
proxy.

When I access the IP address of [nixneo.com](http://nixneo.com), if I make a http request  
with anything other than a Host: header of “[nixneo.com](http://nixneo.com)”, I get a 302  
redirect to [http://nixneo.com/](http://nixneo.com/)

So to get useful content back in a proxy\_pass location, I’d need to set  
the correct Host header.

All the best,
