According to your description and codes, I guess there is something wrong with your custom reponse.
Could you please post more details information about how you define your reponse class?
As far as I know, if you want to set the session ,you should return session id to client side and the client will store the session into the cookie.

Hi Brando,
Response class is very simple class just hold statusCode and statusMessage properties.
namespace integration.App_Code { public class response { public string statusCode; public string statusMessage; public response() { statusCode = "200"; statusMessage = "OK"; } public void createResponse(string code, string message) { this.statusCode = code; this.statusMessage = message; } } }Member
