am creating a web application in using c# with asp.net.
in that am using login page only as normal aspx page. other pages are using masterpage.
when i click logout button in masterpage. page will redirect to login page. after that if i click browser back button it was moving to previous page. how can i prevent this.
am using this following code in master page aspx page. And My log out button code is below.
<%if (!Page.User.Identity.IsAuthenticated)
{ %>
<script type = "text/javascript" >
function preventBack() { window.history.forward(); }
setTimeout("preventBack()", 0);
window.onunload = function() { null };
</script>
<%} %>
But exactly what i need is once if login page loaded or logged out then it wont go to previous page.
thanks in advance.
