What's the best way to adjust the path destination for a routing table created in the global.asax Application_Start event based on the domain/sub domain/host? The following worked in IIS6, but with IIS7 the request object is decoupled from the Application_Start event and therefore does not work anymore: Dim strHost As String = Context.Request.Url.Host Dim strDir As String = "" If strHost.Contains("domain1.com") Then strDir = "area1/" Else strDir = "area2/" End If routes.MapPageRoute("Search", "Search", "~/" & strDir & "search.aspx")
