Even I faced the same situation before...and didn't have any help. try these things maybe these will work for you

in login page <head> tag:
```
<script type="text/javascript">
    window.history.forward();
</script>
```
in Logout Button I did this:
```
protected void Btn_Logout_Click(object sender, EventArgs e)      
{
    connObj.Close();
    Session.Abandon();
    Session.RemoveAll();
    Session.Clear();
    HttpContext.Current.Session.Abandon();
}
```
and on login page I have put the focus on Username textbox like this:
```
protected void Page_Load(object sender, EventArgs e)
{
    _txtUsername.Focus();
}
```
hope this helps... :) someone plz teach me how to edit this page...

<script>
    $(document).ready(function() {
        function disableBack() { window.history.forward() }

        window.onload = disableBack();
        window.onpageshow = function(evt) { if (evt.persisted) disableBack() }
    });
</script>
