Method and system for providing a delta information output-stream

Methods and systems to provide and use a data-structure (921-OS) that is created as an output-stream on a server to enable delta-handling in server-pages. The server stores a page-document that includes a plurality of page-components and further stores a browser-document that comprises a plurality of browser-components (150-0, 150-2, 150-3). Each browser-component (150-0, 150-2, 150-3) corresponds to a page-component. The data-structure (921-OS) includes a page-buffer (921-P). The page-buffer (921-P) is the root-node of a document structure (160); The data-structure (921-OS) further includes the plurality of browser-components (150-0, 150-2, 150-3), wherein the page-buffer (921-P) and the browser-components (150-0, 150-2, 150-3) have relationships that reflect the structure of the browser-document (150).
