<body onbeforeunload="ConfirmClose()" onunload="HandleOnClose()">

where ConfirmClose() asks you if you really want to close, and HandleOnClose() does something as you close the tab.

Thanks for the instant replay. But this solution will not help me. because when we click on each link it will call the ConfirmClose() function. it should not for me. and i am using master page. and it contains so many links. when we close the home page then only i need to find the close event.
