Subdomains and Zend Framework

Hi All,

I have a file system layout similar to the recommendation at http://framework.zend.com/manual/en/zend.controller.html#zend.controller.quickstart.go.directory
I would like to work with subdomains such as http://chicago.example.com and http://newyork.example.com. I have added these subdomains in my Apache virtual hosts file as well as in the Windows hosts file. Now, how can I make subdomains work in Zend Framework. Should I create folders called Chicago and Newyork and repeat the recommended layout within these folders?

Please guide me.

Thanks!

Jerry.
