How to delete cookies on an ASP.NET website

Question

In my website when the user clicks on the "Logout" button, the Logout.aspx page loads with code Session.Clear().

In ASP.NET/C#, does this clear all cookies? Or is there any other code that needs to be added to remove all of the cookies of my website?

Answer 1

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.
