The purpose of the cache.applyDefaultCache middleware in a server function is to apply a default cache strategy for responses. This middleware is instrumental in optimizing performance by leveraging cached responses for subsequent requests. When this middleware is utilized, it establishes a default caching behavior, ensuring that the applications serve cached content efficiently rather than making fresh calls to the server every time a request is made. This can significantly reduce server load and improve response times for users while maintaining the overall user experience.

When a default caching strategy is applied, it helps in determining how long the responses should be stored in the cache, as well as how they can be reused later. Essentially, it automates and streamlines the caching process, allowing developers to focus on other aspects of application performance. By implementing such a mechanism, applications can achieve optimal performance through reduced latency and server utilization.
