what would be the best approach in creating a full flash website

I see all this heavy Flash/3D websites and it's making me wonder how do they build it having to load it so fast. Let me know your thoughts on what/how would be the开发者_如何学JAVA best practice or approach on this.

Just load pieces as they are needed. Also, make the pieces as lightweight as possible. Go to the server for "heavy" content as required (i.e., bitmapped data, etc.).

Robusto is right on, loading pieces as needed is essential. A quality full flash site is tricky to pull off unless you do it right from the beginning. See example:
