Hi Pablo

Just some quick thoughts which might work (aka haven't tried)

1. Use 2 server Directives

server {
	listen 80;
	server_name *.*.com;

	location / {
	rewrite ^(.*)$ http://yourcomdomain.com permanent;
	}
}

server {
	listen 80;
	server_name *.com;

	location /test {
	proxy_set_header  Host $Host;
	proxy_set_header  X-Real-IP  $remote_addr;
	proxy_pass        http://localhost:8000;
	}
}

2. If Regexp are usable in server_name (are they?)

server {
...
	server_name $*.com;
...
}

Greetings
