Hi all, I've created a survey and I need a way to prevent a single user from completing it multiple times.. my thought was to use a cookie, but I haven't find a good way to do that. I've seen several JavaScript ways but they're all inelegant and I'm not a terribly big fan. Does anyone have a suggestion for a more elegant (doesn't have to be jQuery) way of setting and retrieving a cookie?

Thanks!
