preventing multi refresh to count on stats script
<p>i am working on a project which one of our web application would be somehow JavaScript code to gather <strong>statistical information about visitors</strong> but as far as i know on server side PHP application i should somehow handle the code in a way that multi refresh doesn't count and counting on IP based is not a good idea since many users may have the same IP , cookie or session are also vulnerable to this issue because cookie manager can just wipe out all the cookie related to the site so PHP won't recognize the user and count it new,timeframe jobs and all other way to get-around of this issue are also as far as i know based on cookie or session or ip or a mixture of ip/referrer and all other available data from header, how can i handle it and get more reliable data from users and don't permit them to create fake stats. as i believe there must be a way (i hope so)...!?</p>
