Hello, I'm new to Zend, but not new to PHP.

I'm studying Zend Framework, let's say a study on the job.

I would like to build an application with the structure like this:

- SITE
-- application
---- configs
---- layouts
---- modules
-------- default
------------ controllers
------------ forms
------------ models
------------ views
------------ Bootstrap.php
-------- admin
------------ controllers
------------ forms
------------ models
------------ views
------------ Bootstrap.php
---- Bootstrap.php
-- public
-- library
-- index.php

but just can not, I think my problem is routing to reach the admin module. Who can help me explaining where to intervene?

Thanks for your help even now.
