Abstract

This paper presents a proxy cache for data provisioning SOAP-based Web services. The proposed solution relies on a novel caching scheme to efficiently identify cache hits and provides fine-grained configurability by supporting the definition of caching policies at the service and at the operation levels. The proposal has been evaluated using the logs of service calls of a Web service marketplace. The evaluation results show that an appropriately configured SOAP cache provides major performance benefits in practical settings. Furthermore, it is shown that the LRU (Least Recently Used) replacement policy provides the most effective hit ratio, byte hit ratio and delay savings ratio compared to LFU and Size in case of Web services -- a result that is in line with similar results in traditional Web page caching.
