Request.Cookie

Heelo Experts,

I am having issues in removing Request.Cookie on my ASP.Net page.

-------------------------------------------------------------
I do see the cookies in Request collection. But I could not clean them from my page.

----------------------------------------------------------

?Request.Cookies.Count
3

--------------------------------------------------
?Request.Cookies.Item(0)
{System.Web.HttpCookie}
    Domain: Nothing
    Expires: #12:00:00 AM#
    HasKeys: False
    Item: <cannot view indexed property>
    Name: "state%2Epa%2Eus"
    Path: "/"
    Secure: False
    Value: "564F8D424FAADCACC89595B5798F3606DE081B153C222D544EFBFBC74055BC5A1CE8744AA8A439B50162F9DC9987DD4B23D63B7786684FDFA13C35651FF643DC2B4C6813FCDA8307859E043A040F6AF01D2BC11B6FFB7BF487524040B57289CDE7DECCF1AF9E7EF6EE6B1BBF2FC941E162191367445D952996666A7F42971B95"
    Values: {System.Web.HttpValueCollection}


?Request.Cookies.Item(1)
{System.Web.HttpCookie}
    Domain: Nothing
    Expires: #12:00:00 AM#
    HasKeys: False
    Item: <cannot view indexed property>
    Name: "ASP.NET_SessionId"
    Path: "/"
    Secure: False
    Value: "5mb4k3ua1ezir2afenbxim45"
    Values: {System.Web.HttpValueCollection}


?Request.Cookies.Item(2)
{System.Web.HttpCookie}
    Domain: Nothing
    Expires: #12:00:00 AM#
    HasKeys: False
    Item: <cannot view indexed property>
    Name: ".ASPXAUTH"
    Path: "/"
    Secure: False
    Value: "6984F94F9B76C2170D27C711C30D0990ED4CA4893B2ACE978CAED6F4D758C3D87775572A05EAF0A3BF1CA1F9FF6796BF1CC99F39842860E20CE8B6F6A72391DDB8C05991BE473FDEB015C724B018563CC404EE4C4C1542C3"
    Values: {System.Web.HttpValueCollection}
--------------------------------------------------------------------

?Response.Cookies.Count
0

------------------------------------------------------------------

if you see above results, there is no Response.Cookie but there is some Request.Cookies.

-----------------------------------------------------------

I tried the following syntax: no luck so far.

 ' Work with cookies
                Dim testCookie As New HttpCookie("state%2Epa%2Eus")
                testCookie.Expires = DateTime.Now.AddYears(-30)

                Dim MyCookie As System.Web.HttpCookie = Request.Cookies("state%2Epa%2Eus")
                MyCookie.Expires = DateTime.Now.AddYears(-30)


                Dim objCookieColl As HttpCookieCollection
                objCookieColl = Request.Cookies
                objCookieColl.Remove("state%2Epa%2Eus")

                Dim strUS As String
                strUS = "state%2Epa%2Eus"
                Request.Cookies(strUS).Expires = DateTime.Now.AddYears(-10)
                Request.Cookies.Remove(strUS)
                Request.Cookies.Clear()
                Request.Cookies.Item(0).Expires = DateTime.Now.AddDays(-10)
---------------------------------------------

Can someone help me out with this issue? Thanks
