MACROMEDIA FLASH MEDIA SERVER 2-DEVELOPING MEDIA Develop Manual page 35

After the client is connected to the shared object, the server sends out a synchronization
message for the shared object, which is handled by the
defined on the client. When the client, the server, or any other movie instance makes a change
to the shared object, the server again sends out a synchronization message for the shared
object.
Each synchronization message contains a code that specifies the nature of the change that
occurred to the shared object. The code changes depending on the circumstances. For
example, when a client first connects to a shared object, the code that accompanies the
synchronization message has a value of
successfully modified the contents of the shared object. For a complete list of codes and their
descriptions, see the
SharedObject.onSync
Reference for Flash Media Server 2.

connect to the same remote shared object,
