I'm trying to avoid using a session varible here. Bascially, the user can add a lot of text to a text box. It can be formatted with HTML. When they click a preview button they are redirected to a 2nd page which renders the HTML. It gets the data using PreviousPage cross-page posting. But when they go back to the original page to continue working, I lose the data unless I put it in a session which defeats the purpose of the cross-page posting. Orignally I was just going to pop open the form but again, but then I can't use cross page posting or sessions (unless the data is already in the session when the preview button is clicked).
