it's interesting...

i run this   If Request.Cookies.Item("Count") Is Nothing Then
            Dim cookie As HttpCookie = New HttpCookie("Count")
            cookie.Value = "0"
            cookie.Expires = Now.AddDays(100)
            Response.AppendCookie(cookie)
        Else
            Response.Cookies("Count").Value = CType(Request.Cookies("Count").Value, Integer) + 1
        End If
and the cookie is nothing... but if i do   If Request.Cookies.Item("Count") on the immediate window, i  get all the OLD values, the new one does not get assigned..

you mean that you set Response and Request still has the old value ? try looking at Response.Cookies.Item("Count") on the immediate window. It wont change until the next request.
