Flash & Super Cookies

Description Local Stored Objects (LSOs), or Flash Cookies, have become ubiquitous on most systems due to the extremely high penetration of Flash applications across the Internet.

In fact, many sites have begun using LSOs for their tracking mechanisms because they rarely get cleared like traditional cookies.
