cookie based session vs. not cookie based session

[blackhorse]

Note: If you are using cookie-based sessions, you must call session_start() before anything is outputted to the browser.

This is a note from the php manual.

session is cookie-based or not cookie based, where I set it up? What is difference in the programming? Or it is just a client side thing, if the client side not accept cookie, then session will be not cookie based.

From exactly which php version, session could be not cookie-based?

So use not cookie based session will solve the problem that we want to use cookie/session(cookie based session) but the client not accept cookie?

How exactly not cookie based session works? How should I program with not cookie based session?

Thanks!

The session id is appended to the url.

that is only from php 5 and newer?

And I don't need change any session related codes in the old scripts?

Thanks!

How about reading what the manual says about [man]sessions[/man]?
