Use Server-Side ActionScript to write server-side code for an Adobe Flash Media Interactive Server application. You can use Server-Side ActionScript to control login procedures, control events, communicate with other servers, allow and disallow users access to various server-side application resources, and let users update and share information.

Server-Side ActionScript is Adobe's name for JavaScript 1.5. Flash Media Interactive Server has an embedded Java-Script engine that compiles and executes server-side scripts. This Server-Side ActionScript Language Reference documents the Flash Media Interactive Server host environment classes and functions. You can also use core Java-Script classes, functions, statements, and operators. For more information, see the Core JavaScript 1.5 Reference at http://developer.mozilla.org/en/docs/Core_JavaScript_1.5_Reference. For more information about JavaScript, see "About JavaScript" in the Mozilla Developer Center at http://developer.mozilla.org/en/docs/About_JavaScript.

Server-Side ActionScript is similar, but not identical, to ActionScript 1.0. Both languages are based on ECMAScript (ECMA-262) edition 3 language specification. Server-Side ActionScript runs in the Mozilla SpiderMonkey engine embedded in Flash Media Interactive Server. ActionScript 1.0 runs in AVM1 (ActionScript Virtual Machine 1) in Adobe Flash Player. SpiderMonkey implemented the ECMAScript specification exactly and Flash Player AVM1 did not. The biggest difference between Server-Side ActionScript and ActionScript 1.0 is that Server-Side ActionScript is case-sensitive.
