Flash-Cookies, also called Local Shared Objects (LSOs), are files created by flash animations for Macromedia Flash Player version 6.0 and above. They are used by the animations to store information on the viewers hard disk. The files have the extension ".sol". Unlike normal cookies they can store large amount of information of any kind and are therefore a potential security risk. It is recommended to disallow Flash-Cookies unless they are really needed by the users software. Especially some games will not work properly without Flash-Cookies.
