On code behind write this:

Collapse | Copy Code

C#

protected void Page_Load(object sender, EventArgs e)
   {
      
     HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
     HttpContext.Current.Response.Cache.SetNoServerCaching();
     HttpContext.Current.Response.Cache.SetNoStore();
    
 
   }

and on client side write something like this:

Collapse | Copy Code

JavaScript

<script type="text/javascript" language="javascript">
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;
}
}
</script>
