 LruCache is a thread-safe, in-memory [httpcache.Cache](https://github.com/gregjones/httpcache) implementation that evicts the least recently used entries when a byte size limit or optional max age would be exceeded.
 
 Using the included [TwoTier](https://github.com/die-net/lrucache/tree/main/twotier) wrapper, it could also be used as a small and fast cache for popular objects, falling back to a larger and slower cache (such as [s3cache](https://github.com/sourcegraph/s3cache)) for less popular ones.
