It depends entirely on the HTTP response code the server returns. libcurl is
made to (by default) mimic how browsers treat them, which for 301 and 302 that
it will change from POST to GET - contrary to what RFC2616 says we should.

You can alter the behavior for both 301 and 302 by the use of the
CURLOPT_POSTREDIR option.

CURL_ERROR_SIZE might be clever to use for the error buffer as it will never
be larger!
