An example of a custom Zend Framework route that results in a 301 redirect

Bootstrap.php

<?php

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
	protected function _initCustomRoutes()
	{
                $router = Zend_Controller_Front::getInstance()->getRouter();
		$route = new Mylib_Controller_Router_Route_Redirect('old/route/*', array('controller'=>'content', 'action'=>'index'));		
                $router->addRoute('old_route', $route);
	}
}

Mylib_Controller_Router_Route_Redirect.php

<?php

class Mylib_Controller_Router_Route_Redirect extends Zend_Controller_Router_Route
{
	public function match($path, $partial = false)
	{
		if ($route = parent::match($path, $partial)) {
			$helper = new Zend_Controller_Action_Helper_Redirector();
			$helper->setCode(301);
			$helper->gotoRoute($route);
		}
	}
}

I assumed the reader would already know how to do that, but I have renamed the code sample to be more explicit.
