How to connect the plugin to the front controller?

Plugins for FrontController'a connect like this:
\r

$front = Zend_Controller_Front::getInstance(); $front->registerPlugin(new You_Plugin_Example()); 

It is clear that before the instantiation is necessary to connect a file with the plugin class:
\r

require APPLICATION_PATH . '/path/to/plugins/example.php'; 

But it is better to configure the autoloader. This can be done in several ways:
\r

\r
1. You can download the plugin from your own library. To do this, connect the new namespace:
   \r

   $autoloader = Zend_Loader_Autoloader::getInstance(); $autoloader->registerNamespace('You_'); 

   
   \r
\r
2. You can specify the boot loader prefix and the directory with the plugins:
   \r

   $loader = new Zend_Loader_PluginLoader(); $loader->addPrefixPath('You_Plugin', APPLICATION_PATH . '/path/to/plugins/'); 

   
   \r
\r
3. You can add the necessary directories in the module autoloader:
   \r

   $module = new Zend_Application_Module_Autoloader(array( 'namespace' => 'Example', 'basePath' => APPLICATION_PATH . '/modules/example', 'resourceTypes' => array( 'plugin' => array( 'namespace' => 'Plugin', 'path' => 'plugins/', ), ) )); 

   
   \r
\r

In application\\Bootstrap.php add a method _initControllerPlugins(). If the plugins do not need parameters, it is possible in the application.ini to add the line resources.frontController.plugins
\r
Here's an example:
protected function _initControllerPlugins()
{
$acl = new AclModel();
$auth = Zend_Auth::getInstance();
\r
$frontController = Zend_Controller_Front::getInstance();
$frontController->registerPlugin(new My_Controller_Plugin_Acl($acl, $auth));
$frontController->registerPlugin(new My_Controller_Plugin_AuthCookie($auth));
}
