Web application code decoupling and user interaction performance

An improved web browser architecture for an OOP application for a dynamic web page using a client-side scripting language in JavaScript and Ajax to encapsulate presentation logic as objects manipulated by a mediator class state controller object. The browser code is divided into reusable but decoupled and interacting objects. The objects publish to unknown subscribers, and there is no need for objects to explicitly know of or be bound to other objects subscribing to events, consistent with a delegate model. The state of the web browser can be maintained by the state controller, and bookmarking of the state of the web browser allows reconstruction of a web browser dynamic web page. In a preferred embodiment, a GUI for the web browser controls a SAN.
