C# to  ASP   translation

Can someone show the translation from .NET to classic ASP , either Javascript or VBscript
 for this code that logins in, sets a cookie, then and gets a PDF from a remote web server?  Thanks in advance.

 GetPdf(string page_link, string filename)
    {

        string username = "myusername";
        string pass = "mypassword";
        string codePageName = "UTF-8";

        string loginPostData = "userName=" + username + "&Password=" + pass;
        HttpWebRequest httpRequest = WebRequest.Create("http://sitename/auth.aspx") as HttpWebRequest;
        httpRequest.AllowAutoRedirect = false;
        httpRequest.Method = "POST";
        httpRequest.ContentType = "application/x-www-form-urlencoded";

        Encoding enc = Encoding.GetEncoding(codePageName);
        byte[] bytes = enc.GetBytes(loginPostData);
        httpRequest.ContentLength = bytes.Length;
        Stream reqStream = httpRequest.GetRequestStream();
        reqStream.Write(bytes, 0, bytes.Length);
        reqStream.Flush();

        HttpWebResponse response = httpRequest.GetResponse() as HttpWebResponse;
        string cookie = response.Headers["Set-Cookie"];

        WebClient webclient = new WebClient();
        webclient.Headers.Add("Cookie", " " + cookie.Replace("HttpOnly,", "HttpOnly; "));
        webclient.DownloadFile(pagelink, filename);
       
        Response.ContentType = "application/pdf";
        Response.Clear();
        Response.TransmitFile(filename);
        Response.End();
}
