//{

// HttpCookie myCookie = new HttpCookie("Prno");

// myCookie.Value = String.Empty;

// myCookie.Expires = DateTime.Now.AddYears(-1);

// Response.Cookies.Add(myCookie);

// Response.Cookies.Remove("Prno");

//}

HttpCookie myCookie = new HttpCookie("Prno");

//Here, we are setting the time to a previous time.

//When the browser detect it next time, it will be deleted automatically.

myCookie.Expires = DateTime.Now.AddDays(-1d);

Response.Cookies.Add(myCookie);

//Request.Cookies["Prno"].Expires = DateTime.Now;

Session.Abandon();

Session.Clear();

Response.Cookies.Clear();

Response.Redirect("~/Login.aspx");

}

Know the answer? Post it — somebody with the same question will find it here.

Try something like that:

if (Request.Cookies["userId"] != null) {     Response.Cookies["userId"].Expires = DateTime.Now.AddDays(-1);    }

But it also makes sense to use

Session.Abandon();

besides in many scenarios.
