I've been puzzling over this assertion and I still don't really understand it. By building a facade for Flash Remoting, you *hide* information and you *retain* control - you provide a very specific interface to Flash and how you manage state information is entirely transparent (you can use session scope, a database, whatever). > The intent was a black box: the user requests, the CFC figures out how > to handle it and returns, not vice-versa. And that's exactly how it works. A request is made, the CFC (facade) figures out how to handle it and returns. You are then free to design your server-side code however you like and modular design will probably lead you to create several stateless 'service' CFCs, some stateful 'object' CFCs - and your facade - which can lead to much more reuse. > The problem is, in my case, that an outside developer could > potentially unnecessarily burdening the server with requests to > rebuild a query because an overly agressive application and would ruin > overall performance for everyone. So I think your main concern is that you don't want to expose everything as a Web Service? And of course, you don't need to - the facade is the only Web Service and it can use authentication to ensure that no "outside developer" could call it. The CFC that deals with the query is then kept outside the wwwroot and called as needed from the secure Web Service. > That doesn't even go to the fact that code that could be handled in > one place is now pushed out to every application built around it... so > much for reuse. Pushed out how? A facade *encapsulates* rather than exposes - it encourages reuse. > In short, for Flash Remoting to be more than a 'toy', there needs to > be a mechanism that keeps the object resident at least for the term of > execution. There is - shared scopes on the server.
