Modifying back-end web server documents at an intermediary server using directives

摘要

Network services are provided by a network coupled back-end server that is accessed by an intermediary server such as a reverse proxy server. A service request is received at the back-end server via the intermediary server. The back-end server forms a first document in response to the service request. The first document contains a data generation directive targeted for the intermediary server. The first document is sent to the intermediary server. Additional data is generated at the intermediary server using the data generation directive and a second document is formed using the first document and the additional data. The second document is then sent from the intermediary server to an originator of the service request.
