A mark-up method and system that enables server-managed thick client capabilities using a thin client server, framework, and administration. Active content such as program code, service, and data components, are driven to a thick client platform. The thick client platform is defined through a combination of thick client components, while the thick client components and user interface experience are centrally managed. The thick client container can operate to embed thin client container components, such as a browser, and the thick client container itself can be initially deployed over a network using a thin client.
