When users access the server, by default, they have full access to all streams and shared objects. However, you can use Server-Side ActionScript to create a dynamic access control list (ACL) for shared objects and streams. You can control who has access to create, read, or update shared objects or streams.

When a client connects to the server, the server-side script (main.asc or yourApplicationName.asc) is passed a Client object. Each Client object has readAccess and writeAccess properties. You can use these properties to control access for each connection.
