Abstract
Meta-data is generated by a client proxy based on previous response data received from a server proxy in response to a previous request for a resource. A client in communication with the client proxy makes a new request for the resource. The client proxy creates a modified request by modifying the new request to include one or more elements of the meta-data, and sends the modified request instead of the new request to the server proxy. The server proxy compares the one or more elements to corresponding one or more elements of meta-data stored in a server proxy cache. If all compared elements match, the server proxy instructs the client proxy to deliver response data stored in a client proxy cache to the client. If any of the compared elements does not match, the server proxy sends new response data to the client proxy for delivery to the client.
