Abstract
Techniques are provided for efficiently transferring documents (or files) between a client device and a WS-enabled device. A document is divided into a plurality of distinct chunks. Each chunk is packaged in a separate SOAP message. Each SOAP message includes a document identifier and a data transmission serial number (DTSN). The DTSN uniquely identifies a particular chunk of the document relative to the other chunks of the document. After one or more chunks of the document are transferred, the size of one or more subsequent chunks is adjusted based on changes in the client device, the WS-enabled device, and/or the network connection. Thereafter, each of the one or more subsequent chunks of the document is either larger or smaller than the one or more chunks that were already transferred.
