| defaulting to `/` when the referer is missing. | ||

| ```js | ||
| res.redirect('back') | ||

I'm not sure about removing this, maybe the recommended option should be mentioned req.get('Referrer') || '/'

we can keep it—there's no reason to remove it. Also, we still need to add the reference to the new recommended option (see https://github.com/expressjs/expressjs.com/pull/1835/files#r1997311521).
