来自preDispatch（）的Zend_Controller_Action_Exception

How to I redirect to 404 page ("page not found") at preDispatch? Normally within action I can simply write:

throw new Zend_Controller_Action_Exception('Page is not found!', 404);

And it forwards to the appropriate page. How do I make it work for preDispatch?

this code snippet would help you

$request->setModuleName("module")->setControllerName("error")
                   ->setActionName("error")->setDispatched(true);

or you might use as well

$redirector =
    Zend_Controller_Action_HelperBroker::getStaticHelper('redirector');
