Is there other way to perform Seam conversation to to handle multiple pageflow in web application?

I am reading book, Practical JBoss Seam Project. In the page 74, author ment开发者_开发技巧ioned "motivation for conversations". The concept is to handle multiple pageflow that user can have different sessions for the same page. For details to click here. I google this idea about conversation but I can't get good answer. My question is if I don't use Seam, is there other way to perform the same result?

If I do not use Seam, is there other way to perform the same result ?

Short answer: Session attribute

But keep in mind conversation is handled transparently in a Seam application. You just especify its boundaries - begin-conversation and end-conversation.
