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
Tobias
