It sounds like you want each page to keep it's own values, separate from each other.

• If you can use Post (eg: you can keep from manipulating the URL on the client), hidden input tags can do the job well. You'll certainly want to encapsulate this, since doing it manually would be a huge pain. Otherwise:
• If you're using ViewState, you could use that. Otherwise:
• You get the values or an ID (which would be better. see below) into the URL. A last resort, because the human will be able to screw this up. Or they might bookmark it and cause confusion when they come back a week later.

If the values cannot be sent to the client, then you need to pass a "PageSessionID" or something down to the client. This ID is either a guid (better if security is an issue) or some value you get in a way to guarantee uniqueness. Send to the client in a hidden input tag or in ViewState (or url if no other choice), and store related data on the server based on that ID.
