Implementing caching strategies

There are a number of ways to decide when to create and when to expire the cache items, so we'll look at one of the easier and faster methods for doing so. But if you are interested in developing this further, you might consider other caching strategies; some of which can provide efficiencies for resource usage and performance.

Using Least Recently Used

One common tactic to maintain cache stability within allocated resources (disk space, memory) is the Least Recently Used (LRU) system for cache expiration. In this model, utilizing information about the last cache access time (creation or update) and the cache management system can remove the oldest entry in the list.

This has a number of benefits for performance. First, ...
