Zend Framework Routing: .html extension

This is the plugin I've used in several applications:

/**
 * Removes .html extension from URI, if present.
 */
class Application_Plugin_RemoveHtmlExtension extends Zend_Controller_Plugin_Abstract
{
    public function routeStartup(Zend_Controller_Request_Abstract $request)
    {
        // remove ".html" from the end of the URI
        $url = preg_replace('#\.html$#i', '', $request->getRequestUri());

        $request->setRequestUri($url);
    }
}

A quick search on google yielded the following tutorials:
