Delta-handling in server-pages

A computer program product for delta-handling on a server, wherein the server stores a page-document that comprises at least one component and the page-document is translated into a browser-document that is displayed by a client, the computer program product being embodied by a data carrier or carried by a signal and having instructions for causing at least one processor to:

• receive a request from the client resulting in an update of a specific component of the page-document with an application-delta, wherein the specific component has a writer-function;
• generate a browser-delta by applying the writer-function to the application-delta;
• and
• send the browser-delta to the client for updating the browser-document on the client.

A computer program product for delta-handling on a client displaying a browser-document that is derived from a page-document stored on a server;

• the computer program product being embodied by a data carrier or carried by a signal and having instructions for causing at least one processor of the client to:
• receive a browser-delta from the server, wherein a specific page-component of the page-document has a writer-function that generates the browser-delta on the server by applying the writer-function to a corresponding application-delta;
• and
• update the browser-document with the browser-delta.

A computer system for delta-handling comprising:

• a server, wherein the server stores a page-document that comprises at least one component and the page-document is translated into a browser-document that is displayed by a client;
• the server receiving a request from the client resulting in an update of a specific component of the page-document with an application-delta, wherein the specific component has a writer-function, the server generating a browser-delta by applying the writer-function to the application-delta, the server sending the browser-delta to the client;
• and
• the client receiving the browser-delta from the server and updating the browser-document with the browser-delta.

A server for delta-handling comprising:

• a network connection for receiving a request from a client;
• a memory storing a page-document that comprises at least one component and is displayed by a client;
• and
• a processor translating the page-document into a browser-document stored in the memory, the processor processing the request resulting in an update of a specific component of the page-document with an application-delta, wherein the specific component has a writer-function, the processor generating a browser-delta in the memory by applying the writer-function to the application-delta and sending the browser-delta to the client for updating the browser-document on the client.
