sessions handling whit cookies disabled

Hello All, I'm using sessions (id stored in cookies). But I would like to know if user has cookies enabled or not. I don't know how to check, if sessions doesn't work fine because of disabled cookies. I've checked that, when I disable cookies, every start_session creates new session. I know that I can propagate session id in URL, but I don't want to do this. Does anybody know what to do with it? Thanks in advance. -- Sebastian Baran, Poland mailto:sebab@info.com.pl
