Hi
I have a problem with Download module. My requirement is that, after downloading a document or a file, i need to redirect to another page. Is it possible? I already tried like

1. Response.Redirect("~/xyz.aspx");

2. Server.Transfer

3. Response.Write("<script type="text/javaScript"> window.location.href = '~/xyz.aspx'; </script>");

Here i am putting my Code:

string URL = Server.MapPath("~/xyz.pdf");
        FileInfo fileInfo = new FileInfo(URL);

        if (fileInfo.Exists)
        {
            Response.Clear();
            Response.AppendHeader("Content-Disposition", "attachment; filename=" + fileInfo.Name);
            Response.AppendHeader("Content-Length", fileInfo.Length.ToString());
            Response.ContentType = "application/pdf";
            Response.Flush();
            Response.WriteFile(fileInfo.FullName);

            Response.Write("<script type="text/javaScript"> window.location.href = 'Default.aspx'; </script>");
        }
        else
        {
                    Response.Write("<script>alert('Sorry u cant download file!')</script>");
        }
