How to get the session-object within an IHttpHandler

[Aartware]

I've read all the items about the IHttpHandler and the session-object
and I see nothing wrong with my code, but still I have no session
object.

This is my code:
Imports System
Imports System.Data
Imports System.Web
imports System.Web.Sess ionState
Imports System.Web.UI
Imports System.Web.UI.W ebControls
Imports System.Web.UI.H tmlControls
Imports System.IO

Public Class Upload
Implements IHttpHandler
Implements IRequiresSessio nState

'Public Sub ProcessRequest( ByVal context As HttpContext) Implements
IHttpHandler
'Implements IRequiresSessio nState

'Public Sub ProcessRequest( ByVal context As HttpContext) Implements
System.Web.IHtt pHandler.Proces sRequest',
system.web.sess ionstate.IRequi resSessionState
Public Overridable Sub ProcessRequest( ByVal context As HttpContext)
Implements IHttpHandler.Pr ocessRequest
Dim objSession As HttpSessionStat e = context.current .Session
If context.Request .Files.Count 0 Then
Dim tempFile As String = context.Request .PhysicalApplic ationPath
Dim j As Integer = 0
While j < context.Request .Files.Count
Dim uploadFile As HttpPostedFile = context.Request .Files(j)
If uploadFile.Cont entLength 0 Then
try
Dim outputdir As string = objSession("dir ") & ""

Dim sUploadDir as string = "\\fileserver\t est2\"
if outputdir.lengt h 0 Then
uploadFile.Save As(outputdir & uploadFile.File Name)
Else
uploadFile.Save As(sUploadDir & uploadFile.File Name)
End If
catch ex as exception
Dim sOut as string = "uploaderror.lo g"

If File.Exists(sOu t) Then File.Delete (sOut)
Dim sw As StreamWriter = New StreamWriter(sO ut)
sw.WriteLine (ex.tostring)
sw.Close()
end try
End If
j += 1
End While
End If
HttpContext.Cur rent.Response.W rite(" ")
End Sub

Public Overridable ReadOnly Property IsReusable() As Boolean
Implements IHttpHandler.Is Reusable
Get
Return True
End Get
End Property
End Class

My web.config looks like:
<httpHandlers >
<remove verb="POST,GET" path="Upload.ax d"/>
<add verb="POST,GET" path="Upload.ax d" type="Upload"/>

</httpHandlers>
<httpRuntime maxRequestLengt h="1550000"/>
<sessionState mode="StateServ er"
stateConnection String="tcpip=1 27.0.0.1:42424"
cookieless="fal se"
timeout="200"/>

The start aspx looks like:
<%@ Page Language="VB" AutoEventWireup ="true" enableviewstate ="true"
AspCompat="fals e" Trace="false" Debug="true"%>

<%@ Import Namespace="Syst em.IO" %>
<%@ Import Namespace="Syst em.Data" %>
<%@Import Namespace="Syst em.Data.Common" %>
<script language="VB" runat="server">

Sub Page_Load(sende r as Object, e as EventArgs)
Session("dir")= "\\server\test1 \"
End Sub

No error appears, but all the uploaded files are uploaded in the
test2-directory, but I want them in the directory what is set in the
session-object.

I've started with IIS 5, but now I'm testing with IIS 6. But it's not
making any difference.

I'm hoping that someone can tell me what I've forgotten or what I'm
doing wrong.

Is there anybody out there, who can help me???

The reason why I don't have my session is because of the redirecting
object is not my aspx-page but a flash object.
