how to rewrite or redirect a subdomain?

[Steve Chu]

That's really awesome, Thanks.

We have thousands of xxx subdomains, here's our configure:

server {
        server_name  _  *.yyy.example.com;

        if ($http_host ~ "^(.+?)\.yyy\.example\.com") {
            set  $host  $1;
        }

        rewrite  ^   http://yyy.example.com/$host;
}

The "^(.+?)\." calls a dead loop, because it meet xxx.yyy.example.com,
and redirect xxx.yyy.example.com to yyy.example.com/xxx, then redirect
yyy.example.com/xxx to
yyy.example.com/yyy, then to yyy.example.com/yyy... it seems a mistake.

Does server_name  "*.yyy.example.com" match "yyy.example.com"?
