Have you tried these?

MIDL

Session.Abandon();
Session.RemoveAll();
Session.Clear();

or

MIDL

Response.Buffer = false;
Response.Expires = 0;
Response.Cache.SetNoStore();
Response.AppendHeader("Pragma", "no-cache");

Other ways to Clear Browser History

You can clear browser history through JavaScript....

JavaScript

//clears browser history and redirects url
<SCRIPT LANGUAGE=javascript> {  var Backlen=history.length;   history.go(-Backlen);   window.location.href=page url }</SCRIPT>

OR

C#

Page.ClientScript.RegisterStartupScript(this.GetType(),"cle","windows.history.clear",true);

OR as you say in you logout event:

C#

protected void LogOut()  
{      
     Session.Abandon();      
     string nextpage = "Logoutt.aspx";      
     Response.Write("<script language=javascript>");            
     Response.Write("{");      
     Response.Write(" var Backlen=history.length;");      
     Response.Write(" history.go(-Backlen);");      
     Response.Write(" window.location.href='" + nextpage + "'; ");
     Response.Write("}");      
     Response.Write("</script>");  
}
