Abstract: A method of reducing data comprises storing a data stream from the first application in a cache memory resident in the first computer (5) to create a server base cache entry; storing a data stream in a cache resident in the second computer (6) to create a client base cache entry; evaluating the requests from the second application to determine if there exists a client base cache entry corresponding to the interrogated request; interrogating requests from the second application to determine if there exists a server base cache entry corresponding to the interrogated request; intercepting the data stream corresponding to the response originated by the first application in response to the interrogated request from the second application prior to transmission of the response on the external communication link (35); comparing the intercepted responses to the server base form; sending the difference data to the second computer (6) over the external communication link (35); acquiring the difference data transmitted over the external communication link (35) sent by the first computer (5); reconstructing the response data stream corresponding to the communication from the first application from the client/server specific data stream; combining the client base forms with the difference data received over the external communication link (35) and providing the reconstructed data stream to the second application. The above-described method is carried by means incorporated in the apparatus and by computer-readable means of a computer program product.

Abstract: A method, apparatus and computer program product for reducing the data transmitted over an external communication link from a first application resident in a first computer to a second application resident in a second computer. The method, apparatus and computer program product include storing a data stream from the first application to be provided to the second application in response to a request from the second application in a cache resident in the first computer to create a server base cache entry and in a cache resident in the second computer to create a client base cache entry. Requests from the second application are interrogated to determine if a client base cache entry corresponding to the interrogated request exists and to determine if a server base cache entry corresponding to the interrogated request exists. The response data stream is intercepted prior to transmission of the response on the external communication link and compared to the server base cache entry to provide difference data corresponding to the difference between the intercepted response and the server base cache entry. The difference data is sent over the external communication link and acquired by the second computer which reconstructs the response data stream by combining the client base cache entry with the difference data to create a response data stream which is provided to the second application.
