Abstract: When different client devices request the same document, most of content of the response from the server (i.e. the response document from a web server) will be the same. Embodiments allow the client devices to use fingerprints, i.e. hashes, sent by a capture system to pinpoint only the changing portions of the document instead of sending the entire document. In various embodiments, the client compares client-generated fingerprints for the document with capture system-generated fingerprints for most likely appearing portions of text of the document or related documents to fully represent and sends to the capture system the client document in a compact and efficient way.
