Hi Nathan, The problem is not mine to speak of necessarily. I was trying to help find a solution for another. But from what I understand, they have a online lesson that they dont want people to be able to log in as another user and get the answers to. Here is the their post.

Hi All! I am looking for a solution, I want a user to do a single Login only on a PC . E.g. If a User has logged on my website website.com in Internet explorer, then he cant login on same website in another browser like Firefox etc with same loginid or another. Can I trace MAC address of a single machine to solve this issue? Or is there a concept of GLOBAL COOKIE / Cross Browser Cookie which will work for all browsers in a single machine.. I hope You will help me out

cool; only effective way i can see is to produce a unique (one time) hash in response to every request, and submit that with the answer; that way it's unique to every interaction. And only allow the test to be taken by a specific login once (ie if they've started it, they can't start again) But doesn't effectively stop anything because they could have 2 user accounts, and all the previous matters. you can make it more difficult, can't prevent it. as far as I know anyway! Best, Nathan
