Routing Asp.net Framework 3.5 Sp1

[Pykot]

Hola, estoy creando una aplicacion que utiliza routing de asp.net 3.5
Esto funciona perfecto con el depurador de vs.2010, pero al subirlo al hosting no funciona, el hosting tiene iis6, framework 3.5 sp1, con lo cual debiera de funcionar, pero no.

alguien sabe que se puede hacer para que funcione, adjunto codigos, y espero su ayuda, gracias

IROUTING.VB

Código ASP:

Imports System.Web
Imports System.Web.Routing
Imports System.Web.UI
Imports System.Web.Compilation
 
Public Class iRouting
    Implements IRouteHandler
    Private _virtualPath As String
    Public Sub New(ByVal vPath As String)
        _virtualPath = vPath
    End Sub
    Public Property VirtualPath() As String
        Get
            Return _virtualPath
        End Get
        Private Set(ByVal value As String)
            _virtualPath = value
        End Set
    End Property
 
    Public Function GetHttpHandler(ByVal requestContext As System.Web.Routing.RequestContext) As System.Web.IHttpHandler Implements System.Web.Routing.IRouteHandler.GetHttpHandler
        Dim queryString As New StringBuilder("?")
        For Each value In requestContext.RouteData.Values
            Dim mykey As String = requestContext.HttpContext.Server.UrlEncode(value.Key)
            Dim myvalue As String = requestContext.HttpContext.Server.UrlEncode(value.Value.ToString)
            queryString.Append(String.Format("{0}={1}&", mykey, myvalue))
        Next
        If queryString.Length > 1 Then
            queryString.Remove(queryString.Length - 1, 1)
            HttpContext.Current.RewritePath(String.Concat(VirtualPath, queryString), False)
        End If
        Dim redirectPage As IHttpHandler = DirectCast(BuildManager.CreateInstanceFromVirtualPath(VirtualPath, GetType(Page)), IHttpHandler)
        Return redirectPage
 
    End Function
End Class
 

GLOBAL.ASA

Código ASP:

Imports IronClass
Imports System.Web.SessionState
Imports System.Web.Routing
Public Class Global_asax
    Inherits System.Web.HttpApplication
    Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
        RegisterRoutes(RouteTable.Routes)
    End Sub
    Shared Sub RegisterRoutes(ByVal routes As RouteCollection)
        routes.Add(New Route("offline", New iRouting("offline.aspx")))
        routes.Add(New Route("", New iRouting("/index.aspx")))
 End Sub
End Class
 

WEB.CONFIG

Código ASP:
