Getting onbeforeunload confirmation alert twice, when refreshing the URL?

I am using the window.onbeforeunload for user confirmation, when user leaving the page, but confirmation alert happens twice only in IE.

My code is:

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>User confirmation</title>

<script type="text/javascript">
    /* Used for confirmation , to closing the window */
    window.onbeforeunload = function() {

        return "Are you sure want to LOGOUT the session ?";
    };
</script>
</head>
<body>
<p>Folow the steps which I said in Stack overflow</p>
</body>
</html>

The scenario is ,

Step 1 : Run my code and open it in IE .

step 2 : After the application loads,close the browser window . You will get a confirmation alert.

step 3 : Give the cancel in the confirmation alert.

step 4 : Then refresh the URL by pressing the ENTER button in the address bar.

step 5 : Give ok in the alert.

step 6 : Now you will the confirmation alert once again.

Can anyone tell me how to solve this problem?

This is by design in IE.

Read the remarks where all the things that raise that event are listed.

you can use a timer to avoid this:

window.onbeforeunload may fire multiple times
