Web caching is a mechanism used to store frequently accessed documents at a server closer to the users. In e-commerce applications and financial market services, information contained in the objects delivered by the origin server to the clients can rapidly change with time. Therefore, the challenge is not only to locate a cache that contains the required object but also to select the most current version of the object out of all the possible caches. While there are several approaches to locate the cached objects in the Internet in the case of static objects, the extension of these methods to rapidly changing objects is not straightforward. As such, we developed a new method called the selective summary cache to locate the best possible version of the object. In this paper, we present the simulation results that compare the performance of selective summary cache with that of the summary cache. Following on from the results of the simulations, we were able to introduce modifications to improve the performance of the selective summary cache.
