Access httponly cookie from server side (ASP.NET 4.5)

Question

I am trying to retrieve an httponly cookie over https from code behind and then set to session variable to retrieve from web form page. The code is on the same domain.

HttpCookie cookie = Request.Cookies["CookieName"];
            if (cookie != null)
            {
                string token_value = cookie.Value.ToString();

                Session.Add("TestCookie", token_value);
            }

In my web form, I try to retrieve the session variable, but value is null.

<script type="text/javascript">
        var cookie_value = '<%= Session["TestCookie"] %>';
        alert(cookie_value);
    </script>

Answer 1

Instead of

Session.Add("TestCookie", cookie);

I think you mean to write

Session.Add("TestCookie", token_value);
