session updates too slow

Hi again,

I have a puzzling experience with a flag (English/Swedish) that I use for letting the user choose language of the web site. For some reason the page does refresh but the language settings aren't updated the first time the flag is clicked, but after that, it's updated every time. I guessed it had to do with EnableViewState or so, but I can't spot the error. Please help me out if you spot this silly error that's driving me crazy.

The sub for changing the session (and cookie too):

Protected Sub FlaggaImageButton_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles FlaggaImageButton.Click
        If FlaggaImageButton.ImageUrl = "img/unionjack.gif" Then Session("lang") = "en"
        If FlaggaImageButton.ImageUrl = "img/gulbla.gif" Then Session("lang") = "sv"
        Dim c As New System.Web.HttpCookie("langcookie", Session("lang"))
        c.Expires = Now.AddDays(10000)
        Response.Cookies.Add(c)
    End Sub

The ImageButton itself:
<asp:ImageButton ID="FlaggaImageButton" runat="server" Style="z-index: 108; left: 830px; top: 120px; position: absolute;" />

The PageLoad's first lines:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not Request.Cookies("langcookie") Is Nothing Then Session("lang") = Request.Cookies("langcookie").Value
        If Request.Cookies("langcookie") Is Nothing And Session("lang") Is Nothing Then Session("lang") = "sv"

        If Session("lang") = "sv" Then
            TaglineImage.ImageUrl = "img/tagline_sv.gif"
            HemsokLabel.Text = "<a href=""Default.aspx"">Hem/SÃ¶k</a>"
            HemsokLabel.ToolTip = "Till startsidan/SÃ¶k i katalogen"
etc.

Thanks in advance!

You are creating the cookie each time in the click event. You should check if the cookie exists in the page_load event, if it does'nt then create it. In the click event, just set the cookied, don't recreate it.
