Abstract
A method, computer program product, and computer system for client-server communication based on delta transfer. A server of the computer system receives from a client a HTTP request for transferring a current image page, compares the current image page and a saved image page which is stored on the server for the client. Based on the comparison, the server of the computer system constructs delta contents between the current image page and the saved image page. The server of the computer system updates the saved image page on the server with the current image page and sends a HTTP response comprising the delta contents to the client.
