Abstract
The amount of information that must be transmitted from an Internet server to a user's computer or workstation when the user requests an Internet object, for example, by clicking on a URL in a web browser application, is reduced using a cache-based compaction technique in which the requested object is encoded in the server using information relating to similar objects that were previously supplied to the user. Similar objects available in both a client side cache and a server side cache are selected by comparing the URL of the requested object to the URL's of stored objects. Differential encoding is performed in the server such that the server transmits to the client information indicative of the differences between the requested object and the reference (similar) objects available in the server cache. A corresponding decoding operation is performed in the client, using the encoded version and reference objects available in the client cache.
