## What it is
Spring Session is a Java library providing an API and implementations for managing user session information in Spring applications. It replaces container-specific HttpSession handling with pluggable backends like Redis, JDBC, Hazelcast, and MongoDB, enabling clustered sessions and RESTful session IDs in headers.

## Use cases
- manage http sessions in a redis-backed store
- cluster sessions across multiple tomcat instances
- keep sessions alive over websocket connections
- replace container-specific session handling with a neutral solution
- store webflux websession in a database
- pass session ids in headers for restful apis

## When to choose
- you run a Spring or Spring Boot app needing horizontally scalable sessions
- you want sessions persisted in Redis, JDBC, or another datastore instead of app server memory
- you need container-neutral session management across Tomcat, Jetty, etc.

## When to avoid
- you build a simple single-instance app where default container sessions suffice
- you use a non-JVM stack
- you rely on stateless JWT-style auth with no server-side sessions

## Facets
