How cache-partitioning changes the rules of caching resources in browsers

In the article 'Double-Keyed Caching', author Addy Osmani discusses a new caching strategy focused on efficiently managing data in web applications. As applications grow more complex, effective storage and access to data becomes a key element of their success. Osmani introduces the concept of double keying, which allows for better organization of cached data, a critical aspect for applications that handle large amounts of information. He goes on to explain how this approach enhances application performance by providing quicker access to information and reducing data duplication. The author illustrates his ideas with several code examples and describes the implementation of this concept in modern web technologies. Additionally, he addresses the challenges and limitations developers may face when deploying double-keyed caching in their projects.
