VB.NET 2008, reuse a httpwebrequest

[Zandermander]

Hey guys, i'm working on a program, kind of like a download manager.

I have a background worker set up that handles the download, and it works great the first time, but the second time it just sits and times out.

Function DL(ByVal sURL As String, ByVal pProgress As ProgressBar, ByVal Filename As String)
        'GroupBox1.Show()
        Dim URLReq As HttpWebRequest
        Dim URLRes As HttpWebResponse
        Dim FileStreamer As New FileStream(Filename, FileMode.Create)
        Dim bBuffer(999) As Byte
        Dim iBytesRead As Integer
        BackgroundWorker1.ReportProgress(0)
        Dim rplcr As Integer = 0
        Try
            URLReq = WebRequest.Create(sURL)
            URLRes = URLReq.GetResponse
            Dim sChunks As Stream = URLReq.GetResponse.GetResponseStream
            'pProgress.Maximum = URLRes.ContentLength
            ' BackgroundWorker1.ReportProgress(0)
            Do
                iBytesRead = sChunks.Read(bBuffer, 0, 1000)
                FileStreamer.Write(bBuffer, 0, iBytesRead)
                If rplcr + iBytesRead <= pProgress.Maximum Then
                    rplcr += iBytesRead
                    BackgroundWorker1.ReportProgress(rplcr)
                Else
                    rplcr = pProgress.Maximum
                    BackgroundWorker1.ReportProgress(rplcr)
                    MsgBox("Download Complete")
                    BackgroundWorker1.ReportProgress(0)
                End If
            Loop Until iBytesRead = 0

            rplcr = pProgress.Maximum
            BackgroundWorker1.ReportProgress(rplcr)


            sChunks.Close()
            sChunks.Dispose()
            URLRes.Close()


            FileStreamer.Close()
            UnZip(Filename)
            If IO.File.Exists(Filename) Then
                IO.File.Delete(Filename)
            End If
            MsgBox("Download Complete")

            BackgroundWorker1.ReportProgress(0)
            Return True
        Catch
            MsgBox(Err.Description)
            Return False
        End Try
    End Function

I managed to narrow the problem down to the httpwebresponse URLres, how can i renew this and use it multiple times?

Thanks,
