With php you can put automaticly the session id in the url

http://www.php.net/manual/en/session.configuration.php#ini.session.use-trans-sid

But this might be hard to use with dynamic link (like javascript).

You can link the settings with the IP+Browser...

HTTP is stateless, if your user want to use your site as an application (= with a state) they must enable cookies.
