Abstract
A method and system for responding to a request from a client for a web page using delta caching is described. Building templates for the web at the server(s) is functionally separated and logically remote from the request server. One or more template-builders are logically separated from one or more delta-encoders. Each operates independently to perform its part of delta caching; template-builders build templates for the web page, while delta-encoders use those templates and a received web object to compute delta information for the web page. Delta-encoders, like template-builders, are logically remote from the request server. The delta information for the web page and a reference to the template can be separately sent to the client.
