Jim Zimmerman - ASP.NET, MVC, Ajax and ORM

I don't know about you all , but I think the biggest ajax problem is the "back button problem". For example, I built this cool build a car application and my wife would click the next button and then when she wanted to change something and go back she would hit the back button and say, "What happened? Where did the car go?". That was when I realized that we had to come up with a solution for the back button browser problem in ajax. Well it looks as if Nikhil has come up with a good solution for this problem here: http://www.nikhilk.net/BackButtonSupport.aspx . I haven't had time to implement his stuff, but he is the father of Atlas, so I am sure it probably works as advertised. He has some great stuff on his site on how to implement it.
