I wasn't to sure of where to put this so i put it here.
you know how on a lot of pages if you click on a link it turns a different color. so when you come back to that page on your next visit, you know which links you have clicked on and which you haven't. Well how do you do the same thing but so that it only lasts for that persons visit, and when you come back to that page the next time, it has returned to its origional color?
any help would be greatly appreciated.
