What are they? what can they do?
I have a form but I dont want them to submit it more then one per a time period. Can I do this with sessions or do I have to use cookies?
PHP's session handling uses cookies if they are enabled in the browser or URL propegation if they are not to remember who someone is.
Using sessions, you could then store the last time they submitted something as a session variable.
would it only last until they re connected?
