Hi, I am busy building an application that requires one time voting and to get around the user deleting a cookie that I set im keeping a hash on my side which I then try match before allowing anything.

I assume this is backed by a db of some sort. $query = "update user set has_voted=NOW() where userid='x'"; so you can also see when the user voted. Maybe record the ip etc as a record to back up your assertion they have voted but as you say, ip is not a very reliable indicator. -- Postgresql & php tutorials http://www.designmagick.com/
