DefaultHttpClient httpclient = new DefaultHttpClient();

HttpGet httpget = new HttpGet("https://");

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://");

List <NameValuePair> nvps = new ArrayList <NameValuePair>();
nvps.add(new BasicNameValuePair("IDToken1", "username"));
nvps.add(new BasicNameValuePair("IDToken2", "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());

httpclient.getConnectionManager().shutdown();
}
