Abstract
A method, apparatus and computer program product for caching data received from a first application and to be provided to a second application in response to a request from the second application. The method apparatus and computer program products including storing a data stream to be received from the first application and to be provided to the second application in a cache to create a client cache entry corresponding to the request from the second application. The time of creation of a client cache entry is also stored to create a client cache entry time record. Requests from the second application are interrogated to determine if a client cache entry exists corresponding to the request. The client cache entry time record for the client cache entry corresponding to the request from the second application is evaluated to determine if the client cache entry corresponding to the request from the second application was created within a predetermined client coherency time interval prior to the second application requesting the information. The client cache entry is supplied to the second application in response to the request if a client cache entry for the request from the second app…
