Actually, 302 means “repeat the same request at this other URI”
whereas 303 means “please retrieve this other URI using GET.” The
difference is that strictly according to RFC, 302 means the
request should be repeated with the same method, so if you return
a 302 to the browser in response to a POST, the browser would
have to repeat the full POST at the redirect target address.

So for POST-redirect-GET, 303 is the correct redirect status.
Note though that 303 was introduced in HTTP 1.1; if the client
sent you a HTTP 1.0 request, you have no other choice than 302.
