asp.net post xml to redirecting page

I posted an xml data from Desktop application to asp.net wep page. I can read xml at web page but if I redirect the page to another page, I get error at Desktop app. My codes are below. Thanks for help.

Desktop app:

    static void Main(string[] args)
    {
        post();

        Console.WriteLine("Post process is successed...");
        Console.Read();
    }

    private static void post() {
        System.Net.WebRequest req = null;
        System.Net.WebResponse rsp = null;
        try {
            req = System.Net.WebRequest.Create("http://localhost:5318/Account/XMLReader.aspx");
            req.Method = "POST";
            req.ContentType = "text/xml";

            StreamWriter writer = new System.IO.StreamWriter(req.GetRequestStream());
            writer.WriteLine(getXmlData());
            writer.Flush();
            writer.Close();

            rsp = req.GetResponse();
        } catch {
            throw;
        } finally {
            if (req != null) req.GetRequestStream().Close(); // *****Error occures here****
            if (rsp != null) rsp.GetResponseStream().Close();
        }
    }

asp.net page code:

    protected void Page_Load(object sender, EventArgs e)
    {
        Page.Response.ContentType = "text/xml";
        System.IO.StreamReader reader =
        new System.IO.StreamReader(Page.Request.InputStream);
        String xmlData = reader.ReadToEnd();

        Response.Redirect("/Account/Login.aspx");
    }
