Local shared objects (LSOs), commonly called Flash cookies (due to their similarities with HTTP cookies), are pieces of data that websites which use Adobe Flash may store on a user's computer.
To prevent cheating, games may be designed to render LSO files unusable if acquired from another location.
For example, a local shared object from " cannot be read by the domain "
However, the first party website can always pass data to a third party via some settings found in the dedicated XML file and passing the data in the request to the third party.
Flash cookies, which can be stored or retrieved whenever a user accesses a page containing a Flash application, are a form of local storage.
Similar to that of cookies, they can be used to store user preferences, save data from Flash games, or to track users' Internet activity.As with HTTP cookies, local shared objects can be used by web sites to collect information on how people navigate them, although users have taken steps to restrict data collection.
