In addition to the expiration we have been writing a value "deleted" or similar to the cookie. In some cases we've discovered that the cookies don't expire immediately and accessing them from js might give false results for a short while.

If you don't set an expiry date to a cookie, by definition it is only session lived. Ie. it will be deleted when the user will close his browser. Thus, no need for clean up.

Basically all that you need is to set cookie's expiry date to some date in the past.

var cookie_date = new Date ( );  // now
cookie_date.setTime ( cookie_date.getTime() - 1 ); // one second before now.
// empty cookie's value and set the expiry date to a time in the past.
document.cookie = "logged_in=;
                  expires=" + cookie_date.toGMTString();

Session information is usually stored on the server. An HTTP request to a page that destroys the session would normally do the trick (using AJAX if you wish).

For cookies you can set the cookie expiry date to the current date, this will expire the cookie and remove it.

var d = new Date();
document.cookie = "cookiename=1;expires=" + d.toGMTString() + ";" + ";";
