Given an absolute URI/URL, I want to get a URI/URL which doesn\'t contain the leaf portion. For example: given http://foo.com/bar/baz.html, I should get http://foo.com/bar/.
url="http://localhost:9572/School/Common/Admin/Default.aspx"
Dim name() As String = HttpContext.Current.Request.Url.Segments
now simply using for loop or by index, get parent directory name
code = name(2).Remove(name(2).IndexOf("/"))
