Spring Cache - Part 2 - Cache Keys

Spring Cache - Part 1 - Introduction

Caching is an extremely important aspect of applications that care about lower latencies. There are a multitude of rules one has to adhere to while setting up a cache, in order to optimize the performance; but not overdo it. We will not get into those details in this post. Our focus would be on what Spring provides to enable caching in your applications.

ETags and Browser Cache

Caching resources on the browser is crucial to minimize unnecessary trips to the server and reduce the load on it. This works well for data that is static. But, there are cases where the data changes every once in a while (although less frequently), and you would want the browser to get the latest data without waiting for the cached data to expire. e.g., consider a scenario where a new version of the application is deployed with changes to CSS and javascript, and you want the user to experience these changes without forcing them to refresh their cache manually. One option you might consider is to make these resources non-cacheable and compromise the page performance a bit. Entity tags( or ETags for short) help you cache such resources, without the performance compromise.
