HTTP Cookies and Flash Cookies ( Local Shared Objects ). The Flash Cookies mechanism is not integrated with browser cookie policies at all, and it seems to focus as much on the disk space Flash cookies can take up as on their privacy implications. It also doesn't provide some of the kinds of control over cookies that regular browsers and browser plugins can.
