使用自定义 Vercel 防火墙规则重定向流量
Source: Vercel News
You can now redirect requests to a new page using custom Firewall rules, adding to the existing challenge and block actions.
Publishing custom rules does not require a new deployment and will instantly propagate across the global Vercel Edge Network. Therefore, using custom rule redirects in moderation could provide a fast alternative to Edge Network redirects, particularly in emergency situations.
Firewall redirects execute before Edge Network configuration redirects (e.g. vercel.json or next.config.js) are evaluated.
Custom rules are available for free on all plans.
