this is my code for logout.

<a class="nav" href="login.aspx?mode=1">Sign out</a><br>



If Request.QueryString("mode") = 1 Then
            Session.Abandon()
            Response.Redirect("login.aspx")
        End If

------------------------------------
For login this is my code,

goQuery = "select * from forumlogin where psUsrName = '" & txtUser.Text & "' and pswd = '" & txtPassword.Text & "'"
        cmd.CommandText = goQuery
        dr = cmd.ExecuteReader()
        txtHdnDisplay.Visible = True
        If dr.Read Then
            Session("user") = txtUser.Text
            If IsDBNull(dr.Item("psAdmin")) Then
                Session("flag") = 0
            Else
                Session("flag") = dr.Item("psAdmin")
            End If
            Session("blnLogin") = "True"

            Response.Redirect("index.aspx")
        Else
            txtHdnDisplay.Text = "Enter a valid user id and password"
            txtUser.Text = ""
            txtPassword.Text = ""
        End If
        dr.Close()

You'll need to set your pages to expire immediately so that even hitting the back button will force the browser to reload the page, thus re-testing for the login state.
