What this PR does

Adds a new recipe for implementing a rate limiter middleware in Fiber using Redis.
The middleware limits incoming requests based on client IP and a fixed time window.

Features

• Redis-backed rate limiting
• Configurable time window and request cap
• Adds Retry-After header for better client UX
• Returns 429 Too Many Requests when limit exceeded

Why it's useful

This recipe shows developers how to:

• Integrate Redis with Go Fiber
• Use Fiber middleware pattern
• Handle rate limiting cleanly and idiomatically
• Improve API reliability under load

Folder Structure

rate-limit-redis/ ├── config/ │ └── redis.go ├── handlers/ │ └── home.go ├── middleware/ │ └── limiter.go ├── main.go

How to Run

1. Start Redis locally or via Docker: docker run -p 6379:6379 redis

2.Run the project: go run main.go

3.Test with: curl http://localhost:8080/home
