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?
