 To make your debugger happier, disable all PHP class caches by removing the
 call to ``loadClassCache()`` and by replacing the require statements like
 below::
 
     // ...
 
-    // require_once __DIR__.'/../app/bootstrap.php.cache';
-    require_once __DIR__.'/../app/autoload.php';
+    // $loader = require_once __DIR__.'/../app/bootstrap.php.cache';
+    $loader = require_once __DIR__.'/../app/autoload.php';
     require_once __DIR__.'/../app/AppKernel.php';
 
     use Symfony\Component\HttpFoundation\Request;
 
     $kernel = new AppKernel('dev', true);
     // $kernel->loadClassCache();
-    $kernel->handle(Request::createFromGlobals())->send();
+    $request = Request::createFromGlobals();
