Session Management with Redis

User sessions are how web applications remember you! When you log in, add items to a cart, or navigate pages, your app tracks your state using a session.

Traditionally, sessions might be stored directly on the web server's memory or via small files (cookies) on your browser. This works for simple setups, but can become a bottleneck.

As applications grow, traditional session storage faces challenges:

• Scalability: If you have multiple web servers, how do they all know about the same user's session?
• Reliability: What happens if a server crashes and all in-memory sessions are lost?
• Performance: Retrieving session data quickly is crucial for a smooth user experience.

Redis solves these by providing a fast, centralized, and persistent store for session data, accessible by all your application instances.
