Personally I'd have gone the HTTP_REFERER route rather than cookies. Still
not very reliable if the user is with an ISP that uses Dynamic IPs as all
they need to do is disconnect and re-connect but it's still better than
cookies (IMHO anyway).

I am developing a voting system. How to preventing a user votes
continuously? Maybe cookie is useful here, but I don't know how to use it.
Could you give me a example? Thanks.
