Question

i am lost, now the most simple things wont work for me.

Okay, so if i run this script with only Step1 – It will returns “NotNull” – good!

If i then run it With only Step 2 it would as expected return “Null” – good!

But if i then remove Both Step 1 AND 2 (After removing the cookie with step2)
It switches back to “NotNull” – Baad!

How can that be? How can i check if a cookie is Null !?

Hope you can help 🙂

        //Step 1
        HttpContext.Response.Cookies.Add(new HttpCookie("test") { Name = "test", Expires = DateTime.Now.AddDays(2) });

        //Stem 2
        HttpContext.Request.Cookies["test"].Expires = DateTime.Now.AddDays(-2);
        HttpContext.Request.Cookies.Remove("test");
        HttpContext.Request.Cookies.Clear();


        string test = "Null";

        if (HttpContext.Request.Cookies["test"] != null)
        {
            test = "NotNull";
        }

        return Content(test);

In the second step you are trying to modify cookies but you still working with Request object. To submit your modifications you need Response object. So, after your 2nd step cookies still alive.

    //Stem 2
    HttpContext.Response.Cookies["test"].Expires = DateTime.Now.AddDays(-2);
    HttpContext.Response.Cookies.Remove("test");
    HttpContext.Response.Cookies.Clear();
