📝 Walkthrough

Walkthrough

A new redirect rule was added to vercel.json that matches all request paths (/(.*)) when the request host is i18n.npmx.dev, redirecting them to https://main.npmx.dev/translation-status. No other redirect rules or configuration were changed.

Not sure if we should use rewrites instead redirects, check https://vercel.com/kb/guide/can-i-redirect-from-a-subdomain-to-a-subpath

Vercel redirects/rewrites don't mention this case.
