I work for an online web survey company -- our participants are compensated based on the length of the study they participate in. I'm kind of lazyTo verify the compensation is correct, I would like to track it automatically via cookies to compare with manual counts. Also, every participant might have a different count, so I'd like to be able to more accurately compensate. Time is not very effective since someone could walk away and come back later.
Every survey works like this "participation page".php (domain1) ----> redirect.php(domain2) --> "external survey"(not mine) ----> "endredirect".php (domain2) ---> "Thanks Page"(domain1).
Currently I record the time when you leave the participation page, and when you return to the end page and calculate the number of minutes and estimate how much you should receive.
Is it possible to see a history using a cookie when our participant gets back to the end-page? If possible I just want to count backwards to the start page.
Thanks
