I am implementing a questionnaire on the web and I'd like for each block of questions to have its own "page" so the user doesn't have to scroll. However, page loads have two problems: a) they take time (and have a noticeable flicker/refresh) and b) such an approach would force me to do a data table insert plus multiple updates (or store it all in my session).

How can I use JQuery to let the user page through the questionnaire on the client side, answering questions as he goes? I'll then be able to handle the data store when all the answers are submitted at the end.

One other thing...is there a way to make sure that the session doesn't time out if the user takes awhile?
