Send String From Masterpage to Content Page

Let's say I have this in my masterpage:

Partial Class MasterPage2
    Inherits System.Web.UI.MasterPage
        Public Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim menu As String
        menu = Request.QueryString("ekmenu")
End Sub
End Class

If I wanted to display menu's value by calling it on a content page, how would I do that?  Please let me know if I need to explain myself further.  Thanks for reading.
