A POST receives a redirect. Which status code forbids the user agent from changing the request method during automatic redirection?

Erklärung

307 states as a MUST NOT that the user agent may not change the method; 308 plays the same role for permanent redirects. For 301 and 302 the spec explicitly permits a user agent to rewrite POST to GET for historical reasons, and 303 directs the agent to perform a retrieval request instead.
