Method, system and computer program product for delta-handling. A server
stores a page-document that comprises at least one component. The
page-document is translated into a browser-document that is displayed by
a client. The server receives a request from the client resulting in an
update of a specific component of the page-document with an
application-delta. The specific component has a writer-function. The
server generates a browser-delta by applying the writer-function to the
application-delta. The server sends the browser-delta to the client for
updating the browser-document on the client.
