Need A Cookie

I am so new to this asp stuff and I am really in need of a cookie code to add to a form I have.

I want to restrict users to filling in the form only once as this is a vote for a contest. I only want people to be able to vote once.
After they hit submit they will see a confirmation page listing thier votes. But if they go back to the form and try to vote (hit submit) again, I would like them to be directed to a page that tells them they have already voted.

Someone please help, I don't know how to write this stuff, and don't even know where to put it for that matter.

I created the form in Frontpage and it is connected to a .mdb Access 2000 database. The database is collecting the ip addresses so if the code could be to exclude ip address that would be great.

Here's the link to the page I need to put it in. http://www.horseplaycentral.com/PHn...s2004voting.asp

Thank you so much in advance, I don't have time to read a tutorial I just need someone out of the kindness of their heart to post a simple script that will do what I need it to and tell me where I am suppose to copy and paste it to. Thanks!
