Abstract
Client and server based copies of a file are maintained in synchronicity as changes are made to the file. Data is compared to a previous version known to both the client and server and a highly compressed representation of the differences between the two is generated. These differences, or “diffs”, are then transmitted, and may use extensions to the HTTP (HyperText Transport Protocol) protocol.
