What's ServerSideSWF?
Server-Side SWF is a project intended to allow the dynamic creation of Flash content on a request-to-request basis. It uses the MTASC ActionScript 2.0 compiler (http://www.mtasc.org) and swfmill (http://swfmill.org) for asset generation.
It is extremely flexible, and can easily be made to work with filters and caching systems.
First Release
The first version of ServerSideSWF has now been released. It is packaged as an Eclipse project and has an example of how the classes work. Make sure that MTASC is on your environment PATH.
I put some API documentation online as well
Update Put up a slightly newer version with a swfmill example.
