Persistent Cookie for Login not working

The remember me feature for login is not working for me.  All other aspects seem to work fine.  When the timeout expires it makes me log in again.  I was under the impression that entering "True" in the redirectfromlogin would set a persistant cookie that overrides the timeout.  What am I doing wrong?



Here is the relevant web config
**************************************
 <authentication mode="Forms">
        <forms loginUrl="admin/login.aspx" name="UCLGN" timeout="1" protection="All" ></forms>
      </authentication>


 <location path="admin">
    <system.web>
      <authorization>
        <deny users="?" />
      </authorization>
    </system.web>
  </location>
************************************

I set the timeout to 1 to exagerate the problem for testing.

Here is my login page code
************************************
 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not IsPostBack Then
            FormsAuthentication.SignOut()
        End If
    End Sub


    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim conn As New SqlConnection(ConfigurationManager.ConnectionStrings("UC").ConnectionString)
        Dim cmd As New SqlCommand("SELECT * FROM vUsers WHERE username = @username and password = @password", conn)
        cmd.Parameters.AddWithValue("@username", Me.txtUserName.Text)
        cmd.Parameters.AddWithValue("@password", Me.txtPassword.Text)
        conn.Open()
        Dim dtr As SqlDataReader = cmd.ExecuteReader(CommandBehavior.CloseConnection)
        If dtr.Read Then
            FormsAuthentication.RedirectFromLoginPage(dtr("idUser"), Me.chkRememberMe.Checked)
        Else
            Me.lblLoginMessage.Text = "Invalid Login"
        End If
    End Sub
