Nginx Vhost

[siefke_listen at web.de]

Hello, 

i have installed Nginx 1.0.11 on FreeBSD 9. I have configured a Catch All
Host and my Domain. But my Domain Nginx want not accept. He give only
the Catch All Domain back. 

<config>
user  www;
worker_processes  1;
error_log  logs/error.log;

events {
    worker_connections  1024;
}


http {
include       mime.types;
default_type  application/octet-stream;

log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                  '$status $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "$http_x_forwarded_for"';

access_log  /var/log/www/access.log  main;

sendfile        on;
keepalive_timeout  65;

server {
listen       80;
server_name  _;
access_log   logs/access.log  main;

location / {
root   /usr/local/www/nginx;
index  index.html index.htm;
}

error_page  404              /404.html;
error_page   500 502 503 504  /50x.html;
location = /50x.html {
root   /usr/local/www/nginx-dist;
}
}

#silviosiefke.de
server {
listen	     80;
server_name  silviosiefke.de;
access_log   /usr/local/www/vhost/silviosiefke_de/log/access.log main;
error_log    /usr/local/www/vhost/silviosiefke_de/log/error.log;


location / {
root   /usr/local/www/vhost/silviosiefke_de/html;
index  index.html index.htm index.php;
}

error_page   500 502 503 504  /50x.html;

location = /50x.html {
root   /usr/local/www/nginx-dist;
}		
	
#location /article-(\d+)\.html$ {
#try_files $uri $uri/ /blogdetail.html?id=$1;
#}
	
# pass the PHP scripts to FastCGI 
#location ~ \.(php|htm|html)$ {
#fastcgi_pass   127.0.0.1:9000;
#fastcgi_index  index.php;
#fastcgi_param SCRIPT_FILENAME  /usr/local/www/vhost/silviosiefke_de/html
$fastcgi_script_name; 
#include /usr/local/etc/nginx/fastcgi_params; #}

#location ~ /\.ht {
#deny  all;
#}
}
}
</config>

When i give the ip nginx use root /usr/local/www/nginx and when i call
silviosiefke.de, nginx give back the root /usr/local/www/nginx. 

Where is the mistake? Thanks for help.

Silvio
