More subdomain mapping (dynamic 'root'?)

[miradev]

I want to be able to map submains and urls to determined locations on disk, if they exist.

The URL structure is something like: http://.admin.domain.com/

Where  would letters, numbers and underscores , and  is a domain name (e.g.  http://cnn.admin.domain.com/www.cnnminiblog.com)

Nginx should check if /var/www/clients//admin//html/ exists and use that as root:

Some horrible pseudo code:


server {
  listen localhost: 80;
  server_name *.admin.domain.com;

  if ($host ~ (*).admin.domain.com) {
    set $client = $1;
    if ($url ~ ^([^/]*)) {
      set $project = $1;
      set $myroot = /var/www/clients/$client/admin/$project/html;
      if ( -e $myroot ){
        root $myroot;
      }
    }
  }
  ...
}


If this is not very 'nginxy', I am very open to alternate solutions.
