✨ Facts about RackCache

1. RackCache is a caching solution for web applications: RackCache is designed specifically for web applications built on the Ruby on Rails framework. It stores full or partial copies of HTTP responses to help improve server performance, reduce latency, and decrease load times for users.

2. RackCache is compatible with the Rack middleware interface: RackCache acts as a middleware component in the Rack stack, which allows it to be easily integrated with Ruby on Rails applications or any other application that uses the Rack interface. This compatibility makes RackCache a versatile and easily implemented caching option for various web applications.

3. Utilizes different storage backends: RackCache allows users to choose from several storage backends to store cached resources, such as file, memory, or distributed cache systems like Memcached or Redis. This flexibility allows developers to select the most appropriate storage system based on their application's requirements, available resources, and performance goals.

4. Supports Cache-Control and Vary headers: RackCache is compliant with the HTTP/1.1 Cache-Control and Vary header specifications, which enables users to have fine-grained control over caching. This includes options such as setting max-age, no-cache, and public/private caching directives for specific content. The Vary header also allows RackCache to handle content negotiation and serve the appropriate response based on varying conditions like user agent or encoding preferences.

5. Built-in caching strategies: RackCache comes with built-in caching strategies like Least Recently Used (LRU), which helps in automatically managing cached resources by evicting the least recently fetched items when the cache limit is reached. This functionality ensures efficient utilization of cache capacity and aims to maintain an optimal caching performance.
