Abstract

Processing a response to a network request using information that was transplanted into the response from a specific portion of the request. A requesting computer system generates an electronic request that includes the specific portion. The requesting computer system then submits the request to a responding computer system, which processes the request to form a response to the request. During processing of the request, the responding system transplants the specific portion of the request to the response. The responding computer system then transmits the response to the request to a processing computer system that processes the request. The processing computer system receives the response and extracts the information from the specific portion of the response. The processing computer system then uses the extracted information to process the request.
