[RESOLVED] winhttp and resuming downloads..how to do it?

I've looked at how resume works in several examples using winsock..and inet and in each case when you stop the download and try to resume it..it takes forever for the file to get going again..sometimes it even times out..and a few other issues too

so how do you make winhttp resume downloads?
the code below is pretty straight forward..i just need to know what needs to be changed to make it support resuming

Code:

---

Public Sub Http_OnResponseStart(ByVal Status As Long, ByVal ContentType As String)
  FileNumber = FreeFile
  mProgress = 0
  mContentLength = CLng(HTTP.GetResponseHeader("Content-Length"))
  lblTotalSize = "Total Size : " & ListView1.ListItems(B).SubItems(4)
  Open FilePathName For Binary Access Write As #FileNumber

End Sub

Public Sub Http_OnResponseDataAvailable(Data() As Byte)

  If ExitMe = True Then
    HTTP.Abort
    Close #FileNumber

    Exit Sub

  End If

  If HTTP.Status = 404 Then Exit Sub
  mProgress = mProgress + UBound(Data) + 1
  Percent = Format(mProgress / mContentLength * 100, "#0.00")

  Dim PauseTime, Start

  PauseTime = 0.01  ' Set duration.
  Start = Timer  ' Set start time.

  Do While Timer < Start + PauseTime
    DoEvents  ' Yield to other processes.
  Loop
  ListView1.ListItems(B).SubItems(5) = Percent & " &#37;"
  Put #FileNumber, , Data

End Sub

Private Sub Http_OnResponseFinished()
  ListView1.ListItems(B).SubItems(5) = "Complete"
  Close #FileNumber

End Sub
