Get cookies after post request

Question

I'm trying to login into a website and store the cookies in order to make further requests being authenticated.

I successfully log in in the site and get a response but i can't manage to store the cookie properly. This is the code I use to log in:

private String makePostRequest(String url, List<String> header_fields, List<String> header_values) {

    String sessionCookie = "";

    HttpResponse response = null;
    HttpClient httpClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost(url);

    //Post Data
    List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(header_fields.size());

    for(int i = 0; i < header_fields.size(); i++){

        nameValuePair.add(new BasicNameValuePair(header_fields.get(i), header_values.get(i)));
    }
    //Encoding POST data
    try {
        httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));
    } catch (UnsupportedEncodingException e) {
        // log exception
        e.printStackTrace();
    }

    //making POST request.
    try {
        response = httpClient.execute(httpPost);
        // write response to log
        Log.d("Http Post Response:", response.toString());
    } catch (ClientProtocolException e) {
        // Log exception
        e.printStackTrace();
    } catch (IOException e) {
        // Log exception
        e.printStackTrace();
    }

    int statusCode = response.getStatusLine().getStatusCode();
    InputStream is = null;
    StringBuilder stringBuilder = new StringBuilder();
    if (statusCode == HttpStatus.SC_OK) {
        HttpEntity entity = response.getEntity();
        if (entity != null) {
            try {
                is = entity.getContent();
            } catch (IllegalStateException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
            byte[] buffer = new byte[1024];
            int length;
            try {
                while ((length = is.read(buffer)) > 0) {
                    stringBuilder.append(new String(buffer, 0, length));
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

     return stringBuilder.toString();
}

With that code I login and get the response string where i can see i have successfully logged in. Any idea about the cookies? Can't manage to get it to work.

UPDATE

This is the code i use to get session cookies

HttpGet httpGet = new HttpGet(url);
Header[] header=response.getHeaders("Set-Cookie");
for(int i =0; i < header.length; i++) {
     httpGet.addHeader("Set-Cookie", (header[i].getValue()));
}

Answer 1

To Get cookies from the HTTP response do

Header[] mCookies = response.getHeaders("cookie");

After the following line

response = httpClient.execute(httpPost);
