What are some methods for persistant user tracking? I need to limit the number of times a person can search for certain material without forcing them to create a login. Currently I am using cookies to limit the number of searches a person can do but, quiting and removing the cookie file easily defeats that. Storing their IP address locally would work but then not everyone has a static ip. Would grabbing the MAC from their ethernet card be doable? Again alot of people use modems. Any thoughts or resources you know of? tks mitch
