Sure, just use the HEADERFUNCTION and parse the headers you get passed to it.
Identifying the first status line in a response should be easy.

I would even prefer to proceed like this:

  1 - CURLOPT_POST301 gets renamed to CURLOPT_POSTREDIR (while of course still
      supporting the old name for a number of years ahead) - of course if
      someone has a better idea for a name I'm open for it.

  2 - CURLOPT_POSTREDIR then takes the original options 0 to act as default and
      1 to change the 301 behavior. Then we add 2 to just change the 302
      behavior and 3 to change both 301 and 302.

  3 - Then we create a few nice defines for these magic values so that we don't
      have to use magic constant numbers in app source code.

What do you say?
