ASP.NET AJAX history and back button support, see

http://quickstarts.asp.net/Futures/ajax/doc/history.aspx

This does exactly what many of us are wanting, namely, it provides total control over the back/forward buttons, seemingly without all the oddities of other methods. I've verified that they are doing this entirely via client-side javascript (i.e., the asp maps to javascript code on loading). Does anyone know how they are making this work? Have they simply masked the same notions as RSH, or are they taking advantage of other interfaces that perhaps we could exploit as well?

On first glance, this looks like the ASP history manager that Bertrand Le Roy blogs about here:

Closing this issue as it's not an RSH bug but a request for comment/info.
