I need to build a Price Quote system on SharePoint, where people can go in to an existing website and instead of adding items to a cart (this company doesn't sell direct) they can add items to a quote, and then print the quote and take it to a dealer.
The issue is, SharePoint doesn't do Session well, and we don't want to mess with the server in any way we don't have to.
How should I best keep a concurrent list of products and accessories in a cart-like way, without using session?
