[mod_python] Cookies and redirect...

This is a feature of Apache. When it sees an error response (all 204 (no
content), 3xx (redirect), 4xx (client error) and 5xx (server error)),
which includes HTTP_MOVED_TEMPORARILY (even though it's not an error
technically), it sends out only req.err_headers_out. It does make a
special provision for the Location header and copy it into err_headers_out
if it's not already there, which is why it makes it through.

You can send both headers by either:

   req.err_headers_out.add('Set-Cookie', morsel.OutputString())
   req.err_headers_out.add('Location:', location)
   return apache.HTTP_MOVED_TEMPORARILY

or

   req.headers_out.add('Set-Cookie', morsel.OutputString())
   req.status = apache.HTTP_MOVED_TEMPORARILY
   return apache.OK
