HttpResponse.Cookies Property

ASP.NET includes two intrinsic cookie collections. The collection accessed through the Cookies collection of HttpRequest contains cookies transmitted by the client to the server in the Cookie header. The collection accessed through the Cookies collection of HttpResponse contains new cookies created on the server and transmitted to the client in the Set-Cookie header.

After you add a cookie by using the HttpResponse.Cookies collection, the cookie is immediately available in the HttpRequest.Cookies collection, even if the response has not been sent to the client.

The following example creates a new cookie named LastVisit, sets the value of the cookie to the current date and time, and adds the cookie to the current cookie collection. All cookies in the cookie collection are sent to the client in the Set-Cookie header with the HTTP output stream.

HttpCookie MyCookie = new HttpCookie("LastVisit");
DateTime now = DateTime.Now;

MyCookie.Value = now.ToString();
MyCookie.Expires = now.AddHours(1);

Response.Cookies.Add(MyCookie);
