Hello,

I am using Nginx 0.7.54 with php 5.2.8 as the web server. When I  
configure  
the host name, like: \*.music.goog.com, I find a very wield phenonmenon  
that  
I can’t get the third level of this domain.

I print this variable in php:  
$\_SERVER[‘SERVER\_NAME’] ; it says: [music.goog.com](http://music.goog.com)

my nginx.conf follows like:  
server  
{  
listen 80;  
server\_name [music.goog.com](http://music.goog.com) \*.music.goog.com;  
index index.html index.htm index.php;  
…  
}

The requirement is I wanna get the third level of domain which is the  
short  
code of countries, (ex: ar, br, cn, us) to set the cookies then redirect  
to  
the concerned page. My idea is to redirect in the php page. I try to use  
url  
parameters with “?country=us” to implement. It’s ok but it’s no use when  
users only input “[http://ar.music.goog.com](http://ar.music.goog.com)” or to show confusing result  
with  
“[http://ar.music.goog.com/?country=us](http://ar.music.goog.com/?country=us)”

Hoping the experts reply.

SERVER\_NAME is server’s name, not Host header from client request.  
Use HTTP\_HOST instead.

If he uses fastcgi, then he may use

- fastcgi\_param SERVER\_NAME $server\_name;

- fastcgi\_param SERVER\_NAME $host;
