Urlwrite

Hi, I am using Urlwrite attachment on Windows Server IIS7. My web page has 4 phpfile.
1.index.php
2.dynamic.php?id=1
3.charge.php?id=1
4.number.php?id=1
I want to Urlwrite directory like this:

dynamic.aspx?id=1/charge.php?id=1
dynamic.aspx?id=1/number.php?id=1

dynamic.aspx?id=2/charge.php?id=2
dynamic.aspx?id=2/number.php?id=2

as a file

x.com/01-canada/charge

x.com/01-canada/number

x.com/02-usa/charge

x.com/02-usa/number

How can I make this file and directory htaccess or IIS web.config?
