A method, system, and/or computer program product generate and present a webpage on a user interface. A request for an initial page view of an initial page is transmitted from a client computer to a server-side layout manager in a server that is OSGi enabled. The client computer receives a copy of the initial page view, a client-side rendering engine, and a client-side layout manager from the server. The client-side layout manager parses out client-side controllers from the client-side layout manager to determine which views are to be pre-fetched before generating a requested webpage. The client-side layout manager invokes the client-side rendering engine to pre-fetch and cache selected views of particular webpages. The client-side layout manager then invokes the client-side rendering engine to build and render the requested webpage from the initial page view and one or more of the cached views.
