I believe you can't disable the close button of browser. It's the default behaviour of client browser. We don;t have any control on users machine browser and disable to close button..

definitely you can use some javascript to open up new window and disable the close or maximize, minimize button of window but not in the browser.

You need to clear or close your session once user close the browser...

You can disable the browser's close button but you can run javascript when the browser is being closed and ask the user for the action.. Please refer the below code.

<script language='javascript'>
function onBeforeUnloadAction(){
var flag=window.confirm("You are closing the window. Do you want to log out. Click 'Ok' to close or click 'Cancel' to stay back");

if(flag) { 
//first log out and then close the browser.
} else { 
window.event.cancel = true;
}

}
window.onbeforeunload = function(){if((window.event.clientX<0) || (window.event.clientY<0)){ onBeforeUnloadAction();}
</script>

Try below code sample

FireFox as in MSIE

----------------------


<html><head>

<title>noClose</title>

<script type="text/javascript">

function noClose(){window.history.forward();}

</script>

</head>

<body onload="noClose();" onpageshow="if(event.persisted)noClose();" onunload="">

...blabla...

</body></html>



It works with IE, Firefox, Safari, Opera.

-----------------------------------------------


<script type="text/javascript">

function noClose(){window.history.forward()}

noClose();

window.onload=noClose;

window.onpageshow=function(evt){if(evt.persisted)noClose()}

window.onunload=function(){void(0)}

</script>
