    if (shouldRedirectToPage(requestCycle)) {
        // the page itself has been added to the request target, we simply issue a redirect
        // back to the page
        IRequestHandler handler = new RenderPageRequestHandler(new PageProvider(page));
        final String url = rc.urlFor(handler).toString();
