This guide family shows how to store web sessions in Redis so multiple application servers can share session state.

## Overview

A Redis-backed session store is a good fit when you need:

* Shared session state across multiple web servers
* Fast reads and writes for authenticated user state
* Automatic session expiration after inactivity
* A simple way to store lightweight user-specific data

The typical pattern is:

1. Generate an opaque session ID
2. Store the session data in Redis under a key such as `session:{id}`
3. Send the session ID to the browser in a cookie
4. Load the session from Redis on each request
5. Refresh the TTL while the session stays active
