why is cookie still working when browser has cookies disabled?

[benmartin101]

It's weird, my firefox has cookies disabled, yet I am still able to retrieve the cookie.

protected void Page_Load(object sender, EventArgs e)
        {
            Response.Cookies["a"].Value = "1";
          
        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            Label1.Text = Request.Cookies["a"].Value.ToString();  //it returns value 1
           
        }

Why is this?
