to all instances and sessions. It is for example very useful to track different users at the same time, or to send messages from one session to another, or the likes.

Well it started from the above where some guy said this magic could track users. I assumed the cookies and if it's tracking users it uses a session id in the url or a cookie, I know of no other way and would really appreciate the education.

But how does it carry from one click to the next?

I don't believe the original poster you quote really had/has a firm grasp on what it actually does. The tried and true example is a hit counter. No matter who hits a page, if that page increases an application variable called "counter" for example, the counter keeps going up. You hit it and it has a value of 1. Then I hit the page and it has a value of 2. The bob hits it and it has a value of 3. And so on. There's no messaging from one session to another, though I don't doubt you could architect some code to operate like that. It's like a 'session' state that's not specific to any one user - a 'commons' area, if you like. Does that help? Also, a second draft of this info, along with a bit of code example in PHP, is in a PDF at http://demo.logicreate.com/index.php/filemgt/main/event=view/pkey=6/phpfaq.pdf
