How to check if a Cookie has expired?

Hi,

What can I use in vbScript to see whether a cookie has expired? Even when I set my cookie to expire in one minute for testing, the tests I've tried for its existance come up true. What I've been using is isNull, but that's not giving me the result I want.

I'm not too knowledgable about cookies in general, so I'm open to both coding suggestions and strategy suggestions. All I need to do is make sure the same computer doesn't vote on a poll more than once per day. I'd really like to cookie to disappear after it expires. What will an expired cookie normally do?

Thanks in advance for any help..
