Caching is a common and effective pattern for scaling applications in near real-time to handle increased load & demand. This is particularly important for cloud-native applications that serve a multitude of users, devices and even other applications. Caching can be applied in several tiers of the application and (HTTP) session state is no exception. Spring Session offers a robust, yet portable, solution that avoids container lock-in without sacrificing robust features like clustering. It seamlessly allows you to plug in different provider implementations, including Spring Session for Apache Geode, to cluster session state in a reliable, consistent, and scalable manner. Following this webinar, you will understand how session state caching using Spring Session with Apache Geode provides a reliable experience to end-users—an experience that is resilient to system failures, constant reconfiguration and continuous changes in both the underlying infrastructure and applications as they evolve.

Spring Session
- Replaces H(pSession in app container (e.g. Tomcat)
- Support for REST-ful APIs by placing Session ID in headers
- Keeps HIpSession alive when receiving WebSocket messages
- Replaces WebFlux’s WebSession in app container neutral way
