How to delete immediately a cookie ?

I try to delete my cookie by setting the expire date in the past.  That works but the cookie is deleted only when I exit the browser.  How can I delete immediately a cookie in javascript ?

Here is a simple script that writes, reads and delete a cookie, i have tried on Mozilla 0.9.1 and Netscape 4.77, and the cookie is deleted immediately, i.e. no problem, you can try it in your browser and see it works or not ...

<html>
<head>
<title>test delete cookie</title>

<script type="text/javascript" language="JavaScript">
<!--

function setCookie()
{
    document.cookie = "testcookie=testing";
}

function delCookie()
{
    document.cookie = "testcookie=;expires=Fri, 02-Jan-1970 00:00:00 GMT";
}

function readCookie()
{
    alert(document.cookie);
}

//-->
</script>
</head>

<body>
<a href="javascript:setCookie()">Set Cookie</a>
<a href="javascript:delCookie()">Delete Cookie</a>
<a href="javascript:readCookie()">Read Cookie</a>
</body>
</html>

ASKER

That method doesn't work with IE5.5. The cookie is deleted only if you quit the browser.

haha ... may be than we can check the value of the cookie and if it is empty, than treat like as it does not exist ~ haha ...

Exactly. That is the way to do it:

cook=getCookie('nameOfCookie')
if (cook) alert('nameOfCookie:'+cook)
else alert('nameOfCookie not set or empty')
