+HttpFoundation Component
+========================
+
+HttpFoundation defines an object-oriented layer for the HTTP specification.
+
+It provides an abstraction for requests, responses, uploaded files, cookies,
+sessions, ...
+
+In this example, we get a Request object from the current PHP global
+variables:
+
+    use Symfony\Component\HttpFoundation\Request;
+    use Symfony\Component\HttpFoundation\Response;
+
+    $request = Request::createFromGlobals();
+    echo $request->getPathInfo();
+
+You can also create a Request directly -- that's interesting for unit testing:
+
+    $request = Request::create('/?foo=bar', 'GET');
+    echo $request->getPathInfo();
+
+And here is how to create and send a Response:
+
+    $response = new Response('Not Found', 404, array('Content-Type' => 'text/plain'));
+    $response->send();
+
+The Request and the Response classes have many other methods that implement
+the HTTP specification.
+
+Loading
+-------
+
+If you are using PHP 5.3.x you must add the following to your autoloader:
+
+    // SessionHandlerInterface
+    if (!interface_exists('SessionHandlerInterface')) {
+        $loader->registerPrefixFallback(__DIR__.'/../vendor/symfony/src/Symfony/Component/HttpFoundation/Resources/stubs');
+    }
+
