What is the expire time you given in myCookie.Expires = ?

Here is my code
HttpContext.Current.Response.Cookies.Clear()
HttpContext.Current.Response.Cookies("isLoggedInAs").Expires = DateTime.Now.AddYears(-30)
HttpContext.Current.Response.Cookies("DomainControl").Expires = DateTime.Now.AddYears(-30)

But, it say null for HttpContext.Current.Response

C#

string subkeyName;
subkeyName = "userName";
HttpCookie aCookie = Request.Cookies["userInfo"];
aCookie.Values.Remove(subkeyName);
aCookie.Expires = DateTime.Now.AddDays(1);
Response.Cookies.Add(aCookie);

VB

Dim subkeyName As String
subkeyName = "userName"
Dim aCookie As HttpCookie = Request.Cookies("userInfo")
aCookie.Values.Remove(subkeyName)
aCookie.Expires = DateTime.Now.AddDays(1)
Response.Cookies.Add(aCookie)
