You could accomplish this using Server.Transfer which would transfer the entire form v13wstat3, etc, over to the new page but has some implications in and of itself (look that up in MSDN documentation).  You could also do your redirect by passing the form variables in the querystring back and forth (even encrypting it using the DotNetNuke encryption methods if you wanted); might be a little hokey that way but you could accomplish it.

But yes, you can definitely achieve it without using Session objects.
