w3UserExit is used by a Web page to indicate that the page is being unloaded so the connection can be closed by the application. When a form is submitted with w3UserExit set to non-null, the call to w3Input, which is waiting for a response from the browser, exits with a completion status of w3_UserExit.
The following incomplete code and HTML segment works with Internet Explorer 4.0 and Javascript.
<body onUnload="chkExit();">
function chkExit(){
var winToClose = null;
winToClose=window.open('', '', 'width=250,height=150');
if ( winToClose != null) {
window.location="/cgi-bin/fccgi.exe?w3cookie=0012136246399 9&w3UserExit=1"
}
}
