I have one page where users going to take exam. I want to restrict users taking exam second time. Is there any way doing that with session.
I think that I can create one session for every users when they enter to exam page and check afterward(when they enter again). But for this i need to keep this session forever(or some time at least) so it is not good idea i think.
Before i did with database. I saved information when they entered to exam and checked. I am curios that is there any other solutions? or better solutions?
Thanks in advance
