Session Passing in PHP4

Hi, I've been looking around for information regarding the propogation of session information in PHP4. I can't seem to find anywhere that tells me if you can automatically transfer from cookie propogation to url propogation if the client does not accept cookies. Can anybody help me here. Also if anyone knows of an oracle oci8 session handler library (for session_create/session_destroy etc) I would be very interested in knowing where it is) Thanks in advance (and probaly lots of thanks afterwards too :-) Regards, Tim Parkin Web Development Manager, Didio Communications Ltd.
