CHAPTER 1

Server-Side ActionScript

Language Reference

Server-side ActionScript is a scripting language on the server that lets you develop efficient

and flexible client-server Macromedia Flash Media Server applications. For example, you can

use server-side ActionScript to control log-in procedures, control events in connected

Macromedia Flash applications, determine what users see in their Flash applications, and

communicate with other servers. You can also use server-side scripting to allow and disallow

users access to various server-side application resources and to allow users to update and share

information.

Server-side ActionScript is based on the ECMA-262 specification (ECMAScript 1.5), which

is derived from JavaScript and lets you access the core JavaScript server object model. Server-

side ActionScript provides global methods and classes and exposes a rich object model for

developing media applications. You can also create classes, properties, and methods. This

dictionary provides detailed information about the classes and their properties, methods, and

events.

Client-side ActionScript is based on the ECMA-262 specification but deviates from the

specification in several places. Server-side ActionScript does not deviate from the ECMA-262

specification. For information about the relationship between server-side ActionScript and

client-side ActionScript, see Developing Media Applications.

Using server-side ActionScript

To use server-side ActionScript with a Flash Media Server application, you write the code, add

the script file to the appropriate server directory, and run the SWF file that connects to the

server. To understand the architecture of Flash Media Server and its applications, see

Developing Media Applications.
