  $response = $this
    ->getTrustedRedirectResponse($callable, $while, $redirect_route_on_exception);

  // Symfony RedirectResponses set a HTML document as content, which is going
  // to be ugly with our long URLs. Almost noone sees this content for a
  // HTTP redirect, but still: overwrite it with a similar HTML document that
  // doesn't include the URL parameter blurb in the rendered parts.
  $url = $response
    ->getTargetUrl();
  $pos = strpos($url, '?');
  $shortened_url = $pos ? substr($url, 0, $pos) : $url;

  // Almost literal copy from RedirectResponse::setTargetUrl():
  $response
    ->setContent(sprintf('<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8" />
        <meta http-equiv="refresh" content="0;url=%1$s" />
