Redirect if there is no PreviousPage

Problem:
An online form has been broken down into several steps. Each step is a single aspx page. Sometimes user goes directly into a step in the middle.

Solution:
To prevent visitor to go to a page directly, below is the code to check to see if there is no previouspage and redirect it to the default.aspx

In VB:
If IsNothing(PreviousPage) Then
Response.Redirect("Default.aspx" )
End If

In C#:
if (PreviousPage == null)
{
Response.Redirect("Default.aspx");
}
