Abstract

Methods, systems and apparatus, including computer program products, for delta handling in server pages. A server method, for processing a page document that has multiple page components, includes generating, for each page component of the page document, a corresponding browser component. The method also includes building a document structure of a browser document corresponding to the page document. The document structure includes a page buffer and the generated browser components. The page buffer and the browser components have relationships that reflect the structure of the browser document. The method can identify a browser delta in the document structure and send the browser delta to an output stream.
