Answer 4

A:

Ok looks good. Tested in all browsers. Added a P3P tag for IE6, not sure if it was necessary though.

<%@ Page Language="VB" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;

<script runat="server">
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
        Response.AddHeader("P3P", "CP=""CAO PSA OUR""")
        Dim passedlocalizeID As String = Request.QueryString("id")
        Dim localizeID As Integer
        If passedlocalizeID IsNot Nothing AndAlso Int32.TryParse(passedlocalizeID, localizeID) Then
            Dim localizer As New Localizer
            localizer.LocalizeTo(localizeID)
        End If
    End Sub
</script>

<html xmlns="http://www.w3.org/1999/xhtml"&gt;
<head runat="server">
    <title>Redirecting . . .</title>
    <meta http-equiv="refresh" content="0;URL=/" />
</head>
<body>
    <form id="form1" runat="server">
    <div>
    </div>
    </form>
</body>
</html>

Answer 5

+1 A:

You're on the right track. As others have mentioned, the cookie would be created for websiteb.com.

To overcome issues with IE you'll probably need to ad a Compact Privacy policy.

Start here: http://msdn.microsoft.com/en-us/library/ms537342.aspx and Google for the rest.
