ASP.NET和Java HttpComponents post请求有问题

Question

DefaultHttpClient httpclient = new DefaultHttpClient();

    HttpGet httpget = new HttpGet("https://www.lectio.dk/lectio/22/login.aspx");

    HttpResponse response = httpclient.execute(httpget);
    HttpEntity entity = response.getEntity();

    System.out.println("Login form get: " + response.getStatusLine());
    if (entity != null) {
        entity.consumeContent();
    }

    System.out.println("Initial set of cookies:");
    List<Cookie> cookies = httpclient.getCookieStore().getCookies();
    if (cookies.isEmpty()) {
        System.out.println("None");
    } else {
        for (int i = 0; i < cookies.size(); i++) {
            System.out.println("- " + cookies.get(i).toString());
        }
    }

    HttpPost httpost = new HttpPost("https://www.lectio.dk/lectio/22/login.aspx");

    List<NameValuePair> nvps = new ArrayList<NameValuePair>();
    nvps.add(new BasicNameValuePair("m$Content$username2", "blabla")); //set your own username
    nvps.add(new BasicNameValuePair("m$Content$password2", "blabla")); //set your own password

    httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));

    response = httpclient.execute(httpost);
    entity = response.getEntity();

    System.out.println("Login form get: " + response.getStatusLine());
    if (entity != null) {
        entity.consumeContent();
    }

    System.out.println("Post logon cookies:");
    cookies = httpclient.getCookieStore().getCookies();
    if (cookies.isEmpty()) {
        System.out.println("None");
    } else {
        for (int i = 0; i < cookies.size(); i++) {
            System.out.println("- " + cookies.get(i).toString());
        }
    }

运行它得到的输出是
