I faced a problem.
When you add multiple Set-Cookie headers to the response
headers.Add(\"Set-Cookie\", \"a=b;Path=/;\");
headers.Ad
You can use the HttpContext.Current.Response.SetCookie
using System.Web;
HttpCookie foo = new HttpCookie("foo", "true");
HttpContext.Current.Response.Cookies.Add(foo);
HttpCookie bar = new HttpCookie("bar", "true");
HttpContext.Current.Response.Cookies.Add(bar);
This will add multiple set-cookies header in the response.
Edit: also, you should add the
in your web.config
