Can we post and access view state in another application in ASP.NET 2.0

We can post back to any page and pages in another application, too. But if we are posting pages to another application, the PreviousPage property will return null. This is a significant restriction, as it means that if we want to use the view state, we are confined, for example, posting to pages in the same virtual directory. Even so, this is a highly acceptable addition to the functionality of ASP.NET.
