hvorfor gemmes cookie ikke?

Hej

Jeg har fundet denne kode her på eksperten til at lave en indkøbskurv, den benytter sig af cookies, men når jeg næste gang åbner min browser er "kurven" tom.
Det passer mig helt fint, da kunden gerne skulle få en tom kurv næste gang han åbner en browser, men jeg underer mig ovor hvorfor??

strMode = Request.QueryString("mode")
strVareNr = Request.QueryString("varenr")

if strMode = "reset" then ' Nulstil kurven
  ' Nulstil kurv
  for each Key in Request.Cookies("Kurv")
    Response.Cookies("Kurv")(Key) = "0"
  next
end if

if strMode = "insert" then ' indsæt 1 stk i kurven
  ' Indsæt vare i kurv
  Found = False
  for each Key in Request.Cookies("Kurv")
    if Key = strVareNr then
      Response.Cookies("Kurv")(Key) = CStr(CInt(Request.Cookies("Kurv")(Key)) + 1) ' Antal = Antal + 1
      Found = True
      exit for
    end if
  next
  if not Found then
    Response.Cookies("Kurv")(strVareNr) = "1"
  end if
end if

if strMode = "delete" then ' Slet en vare fra kurven
  ' Slet vare fra kurv
  for each Key in Request.Cookies("Kurv")
    if Key = strVareNr then
      Response.Cookies("Kurv")(Key) = "0"
      exit for
    end if
  next
end if
