[mod_python] [SPAM] can't set several cookies from the same page

Your first call to req.write() causes the response headers to be sent to 
the client. Once the headers are sent it's too late to set another 
cookie. This is not unique to mod_python - it's just the way cookies 
work. Make sure you set all your cookies (or any other header for that 
matter) before calling req.write()
