If you want to clear the lblValidate.Text when the user goes back to your page after she(he) is redirected, you could write in you page's Page_Load event.
If Not IsPostBack Then
lblValidate.Text = ""
Or if you redirect the user just want to download something, you could let the user download at currentPage and don't use redirect.
