Send Cookies with HTTPWebRequestion through WP8 App - json

Question

I have to send the cookies to server for every subsequent HTTPWebRequest. My code goes below.
class APIManager
{
CookieContainer cookieJar = new CookieContainer();
CookieCollection responseCookies = new CookieCollection();
private async Task<string> httpRequest(HttpWebRequest request)
{
string received;
using (var response = (HttpWebResponse)(await Task<WebResponse>.Factory
.FromAsync(request.BeginGetResponse, request.EndGetResponse, null)))
{
using (var responseStream = response.GetResponseStream())
{
using (var sr = new StreamReader(responseStream))
{
cookieJar = request.CookieContainer;
responseCookies = response.Cookies;
received = await sr.ReadToEndAsync();
}
}
}
return received;
}
public async Task<string> Get(string path)
{
var request = WebRequest.Create(new Uri(path)) as HttpWebRequest;
request.CookieContainer = cookieJar;
return await httpRequest(request);
}
public async Task<string> Post(string path, string postdata)
{
var request = WebRequest.Create(new Uri(path)) as HttpWebRequest;
request.Method = "POST";
request.CookieContainer = cookieJar;
byte[] data = Encoding.UTF8.GetBytes(postdata);
using (var requestStream = await Task<Stream>.Factory.FromAsync(request.BeginGetRequestStream, request.EndGetRequestStream, null))
{
await requestStream.WriteAsync(data, 0, data.Length);
}
return await httpRequest(request);
}
}
Every time i ask for the question people say that i have to set the cookie container with request by following code line.
request.CookieContainer = cookieJar;
and i used it but still server returns the 'token does not match' error. Do i need to talk to the vendor for it?
Following image shows my problem and requirement.

I haven't seen you do something with the cookieJar !
//Create the cookie container and add a cookie.
request.CookieContainer = new CookieContainer();
// This example shows manually adding a cookie, but you would most
// likely read the cookies from isolated storage.
request.CookieContainer.Add(new Uri("http://api.search.live.net"),
new Cookie("id", "1234"));
cookieJar in your APIManager is a member, everytime your instance APIManager, the cookieJar is a new instance. you need to make sure cookieJar contains what the website needs.
