To reliably delete a cookie w/javascript you have to give it a real date in
the past. With IE6 the cookie will not actually disappear until the browser
is closed.

<snippet>
when=new Date()
when.setMonth(when.getMonth()-12)
expiry=when.toGMTString()
document.cookie="groom=nuthin;path=/;expires="+expiry
</snippet>
