Method and system for differencing container files

摘要

A method and system for efficiently updating container objects on remote systems. The method and system involve a server extension which determines whether the files within the container object have changed since the last time they were sent to the client. If they have changed, the server extension sends only the changed files with instructions on how to reconstruct the container object to a client extension. The client extension receives the changes and the instructions and reconstitutes the container object and transmits the container object to the client browser.
