get application?

[facingwest]

I'm working with a setup that follows the following structure,

application
 - app1
 - app2
 - app3

Now by using $this->getRequest()->getModuleName(); within the Zend_Controller_Plugin_Abstract i can get the module that the users are requesting. I can also get the controller and the action the same way. But i can't seem to locate a way of getting the application that there in.

Is this possible?

Thanks.
