Redis Cache

This is a simple Redis cache implementation in Go using the go-redis/redis package.

Installation

To use this package in your Go project, run the following command: go get github.com/your-username/redis-cache

Usage

To use the Redis cache, first create a new cache instance by calling the NewCache function:

cache := redis.NewCache("localhost", "6379", "PASSWORD")

This will create a new Redis client and return a new Cache instance.
