I am trying to implement a modification on my DNN install that will allow me to tell the end user that their cookies are blocked.  I have come up with something, but it is reading the cookie no matter if cookies are blocked or not.  :(  At first, I was trying with my local install, but realizing that my local install is "trusted", I put this on a deployed install and it still reads the cookies when they are disabled.

Here is what I have done in the Page_Load event of the Signin.ascx.vb file:

            '********************************************************************************************'
            ' BEGIN DNN MODIFICATION
            '--------------------------------------------------------------------------------------------'
            MyNamespace.Utilities.Cookies.SetCookie("PageLoad", "True")
            MyNamespace.Common.Mail.SendMailToAdmin("PageLoad Cookie Equals...", String.Format("PageLoad = {0}", MyNamespace.Utilities.Cookies.GetCookieValue("PageLoad")))
            If String.IsNullOrEmpty(MyNamespace.Utilities.Cookies.GetCookieValue("PageLoad")) Then
                DotNetNuke.UI.Skins.Skin.AddPageMessage(Me.Page, _
                    Localization.GetString("ErrorMessage.CookiesDisabled.Header", Me.LocalResourceFile), _
                    Localization.GetString("ErrorMessage.CookiesDisabled.Text", Me.LocalResourceFile), _
                    ModuleMessageType.RedError)
            Else
                If Not String.Equals(MyNamespace.Utilities.Cookies.GetCookieValue("PageLoad"), "True") Then
                    DotNetNuke.UI.Skins.Skin.AddPageMessage(Me.Page, _
                        Localization.GetString("ErrorMessage.CookiesDisabled.Header", Me.LocalResourceFile), _
                        Localization.GetString("ErrorMessage.CookiesDisabled.Text", Me.LocalResourceFile), _
                        ModuleMessageType.RedError)
                End If
            End If
            MyNamespace.Utilities.Cookies.SetCookie("PageLoad", "False")
            '--------------------------------------------------------------------------------------------'
            ' END DNN MODIFICATION
            '********************************************************************************************'

I have also tried setting the cookie on the home page first (Default.aspx.vb), and then checking it here (signin.ascx.vb), but the cookie is read no matter what I do.  :( 

The MyNamespace.Utilities.Cookies methods are as follows:

        Public Shared Sub SetCookie(ByVal key As String, ByVal Value As String)
            'Encode Part
            key = HttpContext.Current.Server.UrlEncode(key)
            Value = HttpContext.Current.Server.UrlEncode(Value)

            Dim cookie As HttpCookie
            cookie = New HttpCookie(key, Value)
            SetCookie(cookie)
        End Sub

        Public Shared Function GetCookie(ByVal key As String) As HttpCookie
            'encode key for retrieval
            key = HttpContext.Current.Server.UrlEncode(key)
            Return HttpContext.Current.Request.Cookies.Get(key)
        End Function

        Public Shared Function GetCookieValue(ByVal key As String) As String
            Try
                'don't encode key for retrieval here
                'done in the GetCookie function

                'get value 
                Dim value As String
                value = GetCookie(key).Value
                'decode stored value
                value = HttpContext.Current.Server.UrlDecode(value)
                Return value
            Catch ex As Exception
                Return String.Empty
            End Try
        End Function

Can anyone tell me why my cookie value is read even when I disable cookies?  Does anyone have a better way of doing this?
