What is microsoft.com using? Any ideas what .mspx stands for? If it is ASP.NET, why is the ViewState

Go to http://www.microsoft.com/ and open any inner page. You'll see that the address bar contains something like http://www.microsoft.com/***.mspx. What is .mspx? Any ideas if this is just a mask for .asp? Are they still using the plain old ASP? If it is ASP.NET, why is the ViewState missing?

it might be a mask for (hopefully php) or asp or any thing else even php has an option in php.in file where you could use asp style brackets ''%26lt;%'' to strat your php code.

I think that ViewState is optional in asp.net which do have security concerns as it is passed on to the client as hidden HTML elements
