c# - HttpClient not storing cookies in CookieContainer

Question

I'm using VS2010 +.NET 4.0 + System.Net.Http (from Nuget).

For a reason which I don't manage to understand, the session cookie which I receive in my HttpResponseMessage is not automatically saved in the HttpClient CookieContainer. Here is what my code looks like:

CookieContainer cookies = new CookieContainer();
HttpClientHandler handler = new HttpClientHandler();
handler.CookieContainer = cookies;
HttpClient client = new HttpClient(handler);

Uri site = new Uri("https://www.mywebsite.com");
var response1 = client.SendAsync(new HttpRequestMessage(HttpMethod.Get,site)).Result;

I can see in the response headers that I have the following:

Set-Cookie: JSESSIONID=FC8110E434C2C6DAB78B4E335024A639; Path=/member; Secure

However my cookie container remains empty ...why ?

Answer 1

Use this piece of code to retrieve cookies from response:

/// <summary>
/// Read web cookies
/// </summary>
public static CookieContainer ReadCookies(this HttpResponseMessage response)
{
    var pageUri = response.RequestMessage.RequestUri;

    var cookieContainer = new CookieContainer();
    IEnumerable<string> cookies;
    if (response.Headers.TryGetValues("set-cookie", out cookies))
    {
        foreach (var c in cookies)
        {
            cookieContainer.SetCookies(pageUri, c);
        }
    }

    return cookieContainer;
}
