Why does Next.js use 307 and 308? Traditionally a 302 was used for a temporary redirect, and a 301 for a permanent redirect, but many browsers changed the request method of the redirect to GET, regardless of the original method. For example, if the browser made a request to POST /v1/users which returned status code 302 with location /v2/users, the subsequent request might be GET /v2/users instead of the expected POST /v2/users. Next.js uses the 307 temporary redirect, and 308 permanent redirect status codes to explicitly preserve the request method used.
