Embodiments described herein relate to an improved technique for preemptive client application request processing based on observed use access patterns and/or models. The system includes a framework engine operable to trace sequences of requests to one or more service provider applications, including which particular client requests are likely to be followed by other particular client requests for each service. Based on the resulting traces, the framework can determine the probability of a particular request B following another particular request A. When request A is retrieved from the service provider application, and when the probability is high enough (e.g. >50%) that request B will follow request A in the sequence of requests, the framework is operable to simulate request B in a background process and provide a response to request B from a local memory storage.
