What Is Server-Side ActionScript?
Server-Side ActionScript is more accurately JavaScript—it is built entirely using the Rhino JavaScript parser (http://www.mozilla.org/rhino). The Rhino implementation of JavaScript was a project begun by Netscape for a never-used all-Java browser. The Rhino project took on a life of its own, however, and is now an open source project housed at the Mozilla web site. Rhino is essentially a JavaScript parser built in Java. For that reason, it is a perfect fit for ColdFusion MX and JRun 4. Macromedia used the Rhino engine for the Server-Side ActionScript implementation in both ColdFusion MX and JRun 4. Currently, these are the only two platforms that support SSAS (the .NET, Java, PHP, and Perl versions of Flash Remoting don’t support SSAS).
