Techopedia explains Super Cookie

There is some debate as to the precise definition of a super cookie. Originally, super cookies were synonymous with flash cookies as this was the first type of tracking mechanism beyond a basic cookie that could be used on the majority of browsers. As technology has progressed, it is possible to track users via other techniques such as HTML5 session storage. Given that browser technology will continue to change it is advantageous to think of supers cookies in terms of their characteristics (permanant storage and difficulty in removal) as opposed to the mechanics of how they are stored on a computer.

Due to privacy concerns, many users and advocacy groups frown on the use of super cookies. However, the potential wealth of data and its use in online advertising have prompted more than a few ad organizations and websites to experiment with these more robust cookies.
