<p>A recorder intercepts a protocol data stream comprising a plurality of packets, sent from a first device to a second device, the protocol data stream representing display data. The recorder copies at least one packet of the protocol data stream. The recorder creates a recording of the protocol data stream using the at least one copied packet. A protocol engine reads the at least one copied packet from the recording of the protocol data stream. The protocol engine uses information associated with the at least one copied packet to regenerate the display data represented by the protocol data stream. In another aspect, a foreground protocol engine receives a request for rendering the contents of a packet in a recording of a protocol data stream, the protocol data stream comprising a plurality of packets. The foreground protocol engine identifies a state-snapshot having an associated timestamp previous to that of the requested packet. The foreground protocol engine displays the requested packet responsive to the identified state-snapshot.</p> |
