I am practicing Cookies in .NET. Its working fine but when I want to clear my cookies, the statement,

Code:
Response.Cookies.Clear
does not work. What gives?

Here's what I do:


(1) Login page

There's a "Remember me on this computer checkbox". When the user presses the login button, I do this:

Code:
Sub btnLogin_Click(sender As Object, e As EventArgs)

    if chkRemember.Checked = True Then
        Dim ckUserName As HttpCookie  = new HttpCookie("UserName")
        ckUserName.value = Trim(txtUserName.Text)
        ckUserName.Expires = System.DateTime.Now.AddYears(4)
        Response.Cookies.Add(ckUserName)
        ckUserName = Nothing

        Dim ckPassword As HttpCookie = new HttpCookie("Password")
        ckPassword.value = Trim(txtPassword.Text)
        ckPassword.Expires = System.DateTime.Now.AddYears(4)
        Response.Cookies.Add(ckPassword)
        ckPassword = Nothing
    End If

    Response.Redirect("AnotherPage.aspx")
End Sub

Sub Page_Load(sender As Object, e As EventArgs)
    if Not (Request.Cookies("UserName") Is Nothing And _
            Request.Cookies("Password") Is Nothing) Then
            Response.Redirect("AnotherPage.aspx")
    End If
End Sub

(2) AnotherPage.aspx

Code:
Sub Page_Load(sender As Object, e As EventArgs)
    If Not (Request.Cookies("UserName") Is Nothing And _
        Request.Cookies("Password") Is Nothing) Then
        Dim StrUserName As String = Request.Cookies("UserName").value.ToString
        Response.Write("Welcome, " & StrUserName & "!")
        Response.Write("<br/><p>If you are not " & StrUserName & ", then click <a href='ClearCookies.aspx'>here</a>.</p>")
    Else
        Response.Write("You are a cookieless *******.")
    End If
End Sub

(3) ClearCookies.aspx

Code:
Sub Page_Load(sender As Object, e As EventArgs)
    Response.Cookies.Clear
    Response.Redirect("index.aspx")
End Sub
