Do not disable expected browser behaviour and you can handle the possiblity at your end, but if you really want to do so, there is one work around here...

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.
