You can retrieve the previous url from the <code>headers</code> property:</p> <pre><code>$request->headers->get('referer'); // Single 'r' everywhere! </code></pre> <p>For additional info, consult:</p> <ul> <li>Symfony2 <code>Request</code> class on <a href="https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpFoundation/Request.php" rel="nofollow">github</a></li> <li>Symfony2 <code>ParameterBag</code> class on <a href="https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpFoundation/ParameterBag.php" rel="nofollow">github</a> </li> </ul>
