  $fb_app_data = fb_app_get_data($fb_app);
  $fb_user_data = $fb_app_data['fb_user'];

  // our configuration
  if ($fb_user_data['require_login'] == FB_USER_OPTION_REQUIRE_LOGIN) {

    // The application is configured to require login on all canvas pages.
    // However, there are exceptions.
    if (isset($_REQUEST['fb_sig_in_profile_tab']) && $_REQUEST['fb_sig_in_profile_tab']) {

      // Redirects are not allowed for the profile tab.
      return FALSE;
