{
案例116://F5;
event.returnValue = false;
event.keyCode = 0;
window.status =我们已禁用F5";
休息；
}
}

window.history.forward(1);
document.attachEvent("onkeydown", my_onkeydown_handler);
function my_onkeydown_handler()
{
switch (event.keyCode)
{
case 116 : // F5;
event.returnValue = false;
event.keyCode = 0;
window.status = "We have disabled F5";
break;
}
}

If you are using forms authentication.

// Page load event of Logout.aspx
FormsAuthentication.SignOut();
Response.Redirect("Default.aspx");

//Session
//in your Global.asax file
void Session_Start(object sender, EventArgs e)
  {
    // Code that runs when a new session is started
      if (Session["UserID"] == null)
      {
          Response.Redirect("Login.aspx");
      }

no need to write any code in Global.asax file....
Use javascript to disable the back button....
