This technique is a method for buffering document data for improved performance and reduced data transfer between a file-serving system and a personal computer when using partial document access methods. The technique is centered around a set of content-sensitive functions that maintain a document caching buffer in memory on the PC. When using partial document access (see the figure), all the data (text and formatting information) for a page or a set of consecutive lines is assembled on the file-serving system and sent to the personal computer for processing. The text information is served by page, and line number and the formatting information is referenced by key. Both sets of this information are stored and processed as variable length records.
