Server-Side Requirements

Every communication component requires one or more Server-Side ActionScript

(SSAS) files, which use the .asc extension. These files exist within the scriptlib folder

of the installation directory for FlashCom and are automatically installed with Flash

Communication Server MX. Fortunately, you can quickly enable communication

components (i.e., make them available for use by your client-side applications) by

loading the components.asc file into the main.asc document of any FlashCom appli-

cation. The components.asc file loads other .asc files into the application instance to
