Redis session store

Store web sessions in Redis with cookie-based session IDs and TTL expiration

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

• Go - Build a Redis-backed session store with go-redis and a local Go demo server
• Java - Build a Redis-backed session store with Jedis and a local Java demo server
• Java (Lettuce) - Build a Redis-backed session store with Lettuce using async and reactive APIs
• .NET - Build a Redis-backed session store with StackExchange.Redis and a local ASP.NET Core demo server
• PHP - Build a Redis-backed session store with Predis and a local PHP demo server
• Ruby - Build a Redis-backed session store with redis-rb and a local Ruby demo server
• Rust - Build a Redis-backed session store with redis-rs, including both sync and async APIs
