I don't understand your question, but you can't stop people going back. If you disabled caching (google "asp.net disable page cache" for code examples) on the page you don't want them going back to you can probably add code to handle the request in a better way on that page.

Just put this javascript on the html section of aspx page above head section.
This causes every back to return with a forward.

<script type="text/javascript">
function disableBackButton()
{
window.history.forward();
}
setTimeout("disableBackButton()", 0);
</script>

Open the webpage in a popup window rather than normal window. So, that you can restrict the popup window from displaying buttons, menus, status and other features.

I've made it on [removed] - it worked.
