+
+Making the Locale "Sticky" during a User's Session
+==================================================
+
+Prior to Symfony 2.1, the locale was stored in a session called ``_locale``.
+Since 2.1, it is stored in the Request, which means that it's not "sticky"
+during a user's request. In this article, you'll learn how to make the locale
+of a user "sticky" so that once it's set, that same locale will be used for
+every subsequent request.
+
+Creating LocaleListener
+-----------------------
+
+To simulate that the locale is stored in a session, you need to create and
+register a :doc:`new event listener</cookbook/service_container/event_listener>`.
+The listener will look something like this. Typically, ``_locale`` is used
+as a routing parameter to signify the locale, though it doesn't really matter
+how you determine the desired locale from the request::
+
+    // src/Acme/LocaleBundle/EventListener/LocaleListener.php
+    namespace Acme\LocaleBundle\EventListener;
+
+    use Symfony\Component\HttpKernel\Event\GetResponseEvent;
+    use Symfony\Component\HttpKernel\KernelEvents;
+    use Symfony\Component\EventDispatcher\EventSubscriberInterface;
+
+    class LocaleListener implements EventSubscriberInterface
+    {
+        private $defaultLocale;
+
+        public function __construct($defaultLocale = 'en')
+        {
+            $this->defaultLocale = $defaultLocale;
+        }
+
+        public function onKernelRequest(GetResponseEvent $event)
+        {
+            $request = $event->getRequest();
+            if (!$request->hasPreviousSession()) {
+                return;
+            }
+
+            // try to see if the locale has been set as a _locale routing parameter
+            if ($locale = $request->attributes->get('_locale')) {
+                $request->getSession()->set('_locale', $locale);
+            } else {
+                // if no explicit locale has been set on this request, use one from the session
+                $request->setLocale($request->getSession()->get('_locale', $this->defaultLocale));
+            }
+        }
+
+        public static function getSubscribedEvents()
+        {
+            return array(
+                // must be registered before the default Locale listener
+                KernelEvents::REQUEST => array(array('onKernelRequest', 17)),
+            );
+        }
+    }
+
+Then register the listener:
+
+.. configuration-block::
+
+    .. code-block:: yaml
+
+        services:
+            acme_locale.locale_listener:
+                class: Acme\LocaleBundle\EventListener\LocaleListener
+                arguments: ["%kernel.default_locale%"]
+                tags:
+                    - { name: kernel.event_subscriber }
+
+    .. code-block:: xml
+
+        <service id="acme_locale.locale_listener"
+            class="Acme\LocaleBundle\EventListener\LocaleListener">
+            <argument>%kernel.default_locale%</argument>
+
+            <tag name="kernel.event_subscriber" />
+        </service>
+
+    .. code-block:: php
+
+        use Symfony\Component\DependencyInjection\Definition;
+
+        $container
+            ->setDefinition('acme_locale.locale_listener', new Definition(
+                'Acme\LocaleBundle\EventListener\LocaleListener',
+                array('%kernel.default_locale%')
+            ))
+            ->addTag('kernel.event_subscriber')
+        ;
+
+That's it! Now celebrate by changing the user's locale and seeing that it's
+sticky throughout the request. Remember, to get the user's locale, always
+use the :method:`Request::getLocale<Symfony\\Component\\HttpFoundation\\Request::getLocale>`
+method::
+
+    // from a controller...
+    $locale = $this->getRequest()->getLocale();

+
+Configuring the Directory where Sessions Files are Saved
+========================================================
+
+By default, Symfony stores the session data in the cache directory. This
+means that when you clear the cache, any current sessions will also be
+deleted.
+
+Using a different directory to save session data is one method to ensure
+that your current sessions aren't lost when you clear Symfony's cache.
+
+.. tip::
+
+    Using a different session save handler is an excellent (yet more complex)
+    method of session management available within Symfony. See
+    :doc:`/components/http_foundation/session_configuration` for a
+    discussion of session save handlers. There is also an entry in the cookbook
+    about storing sessions in the :doc:`database</cookbook/configuration/pdo_session_storage>`.
+
+To change the directory in which Symfony saves session data, you only need
+change the framework configuration.  In this example, you will change the
+session directory to ``app/sessions``:
+
+.. configuration-block::
+
+    .. code-block:: yaml
+
+        # app/config/config.yml
+        framework:
