What's in This Book?
As with any technology, as you move away from creating simple
applications to creating larger-scale, robust, and secure
applications, design and development increase in difficulty. This is
especially true in an environment in which events are occurring in
multiple Flash movies and on the server at the same time.
Coordinating concurrent events introduces an extra level of
complexity that many Flash and web developers may not be used to.
This book addresses these and other problems directly. It describes
in detail how to:
Avoid conflicts when multiple users update data in real time Manage contention for the same resourcesfor example, multiple
users trying to add text to the same shared text area Minimize the effects of network latency Adapt to differences in client bandwidth Use and extend Macromedia's communication classes Design and develop components that work well within
Macromedia's component framework Design applications without Macromedia's framework
using your own set of components Create applications that can scale from a few simultaneous users to
many thousands Create secure applications
The book also includes numerous samples filesespecially in the
later chaptersthat I hope you will find useful, including:
A collection of components such as PeopleGrid, OnlineStatus,
TextChat, SharedText, VideoConference, Authentication, and
PersonalCursor An alternative, lightweight component framework A recording framework for recording and playing back events, audio,
video, and data
The book also includes numerous useful ColdFusion examples to perform
operations beyond the capabilities of FlashCom Server, such as FTP
file copying and database access. All sample code is available on the
book's web site.
