copied!<p>You have to implement it with a kernel listener, this is the way I solve it:</p> <p><strong>Listener</strong> <em>src/Comakai/MyBundle/Handler/SessionIdleHandler.php</em> <pre><code>namespace Comakai\MyBundle\Handler; use Symfony\Component\HttpKernel\HttpKernelInterface; use Symfony\Component\HttpKernel\Event\GetResponseEvent; use Symfony\Component\HttpFoundation\Session\SessionInterface; use Symfony\Component\Routing\RouterInterface; use Symfony\Component\HttpFoundation\RedirectResponse; use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface; class SessionIdleHandler { protected $session; protected $securityToken; protected $router; protected $maxIdleTime; public function __construct(SessionInterface $session, TokenStorageInterface $securityToken, RouterInterface $router, $maxIdleTime = 0) { $this->session = $session; $this->securityToken = $securityToken; $this->router = $router; $this->maxIdleTime = $maxIdleTime; } public function onKernelRequest(GetResponseEvent $event) { if (HttpKernelInterface::MASTER_REQUEST != $event->getRequestType()) { return; } if ($this->maxIdleTime > 0) { $this->session->start(); $lapse = time() - $this->session->getMetadataBag()->getLastUsed(); if ($lapse > $this->maxIdleTime) { $this->securityToken->setToken(null); $this->session->getFlashBag()->set('info', 'You have been logged out due to inactivity.'); // Change the route if you are not using FOSUserBundle. $event->setResponse(new RedirectResponse($this->router->generate('fos_user_security_login'))); } } } } </code></pre> <p><strong>Config</strong> <em>src/Comakai/MyBundle/Resources/config/services.yml (Comakai/MyBundle/DependencyInjection/MyBundleExtension.php)</em></p> <pre><code>services: my.handler.session_idle: class: Comakai\MyBundle\Handler\SessionIdleHandler arguments: ["@session", "@security.context", "@router", %session_max_idle_time%] tags: - { name: kernel.event_listener, event: kernel.request, method: onKernelRequest } </code></pre> <p>Now you can set the <code>session_max_idle_time</code> in <strong>parameters.yml</strong> to 30 * 60 = <strong>1800</strong> seconds (or just hardcode the value wherever you want):</p> <p><strong>Parameters</strong> <em>app/config/parameters.yml</em></p> <pre><code>parameters: ... session_max_idle_time: 1800 </code></pre>
