Try this...
1. Clear the sessions
2. Clear the cache such that browser has no history (this will make back/forward button in browser grayed out disabled.)
code for clearing cache can be put up in code behind as follows:

C#

// Code disables caching by browser. Hence the back browser button
// grayed out and could not causes the Page_Load event to fire 
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(DateTime.UtcNow.AddHours(-1));
Response.Cache.SetNoStore();

You can add somethin similar in form aspx if you want to place it there:

<meta http-equiv="Cache-Control" content="no-cache">
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Expires" content="0"></meta></meta></meta>
