Actually we can't disable the browser back button. In this code we are clearing the browser cache.

Add the following code to the Page_Load event of ASP.NET web page

// Disable the Cache
Response.Buffer= true;
Response.ExpiresAbsolute=DateTime.Now.AddDays(-1d);
Response.Expires =-1500;
Response.CacheControl = "no-cache";

// Check for your SessionID
if(Session["SessionId"] == null)
{
   Response.Redirect ("Home.aspx");
}

hi good one in another approach we can do
<script language="text/javascript">
function back()
{
windows.history.forward(1);
}
</script>
<body onload="back()">
....

hi friends
you are right at your functionality requirements
but as per my view following code is also work at their

Response.Cache.SetCacheability(HttpCacheability.Private);

            Response.Cache.SetCacheability(HttpCacheability.NoCache);

try it
it will also disabled back button.
