Server-Side ActionScript
There are two distinct types of ActionScript: client-side ActionScriptwhich includes both ActionScript 1.0 and ActionScript 2.0and the server-side version, known as Server-Side ActionScript (SSAS). Client-side ActionScript is used to create .swf moves that run in the Flash Player on the user 's machine. Server-Side ActionScript is stored in . asc files that run on the FlashCom Server. As you'll see, Server-Side ActionScript does not support the OOP features of AS 2.0. Instead, Server-Side ActionScript is like JavaScript 1.5, which is very similar to AS 1.0 (all are based on ECMAScript 3). For more on the differences between client-side and server-side scripting, see Section 4.2 in Chapter 4. FlashCom SSAS is not the same as the Server-Side ActionScript that can be used to script Flash Remoting applications in ColdFusion and JRun. For more information on that topic, see Flash Remoting: The Definitive Guide (O'Reilly).
