The userData behavior persists information across sessions by writing to a UserData store. This provides a data structure that is more dynamic and has a greater capacity than cookies. The capacity of the UserData store is 64K per page, with a limit of 640K per domain.The userData behavior persists data across sessions, using one UserData store for each object. The UserData store is persisted in the cache using the save and load methods. Once the UserData store has been saved, it can be reloaded even if Microsoft® Internet Explorer has been closed and reopened.For security reasons, a UserData store is available only in the same directory and with the same protocol used to persist the store.Setting the userData behavior (proposed) class on the HTML, HEAD, TITLE, or STYLE object causes an error when the save or load method is called.
