RESTful Java Web Services - Third Edition

Caching using RESTEasy

REST APIs are being used for a majority of B2B interactions, and often, they are constrained by the strict performance obligations to deliver the agreed quality of service. Though network-level caching may be helpful to improve throughput, it does not fully address performance needs. In cases where the underlying state of the data is not prone to frequent changes, such as static data, and there is a significant load on the system, it becomes advantageous to use caching to improve the response time. To facilitate the implementation of caching for RESTful services, RESTEasy comes with the following features:

• Cache-control annotations for server-side caching
• Client-side caching
• Multipart content handling
