Power Cache is a utility that helps override request caching and force-fetches specific requests based on URL patterns you provide. This utility is designed to help you during the development of your web application. While working on a web application, you might face the problem of the browser not being able to fetch the assets you need. It might be due to a number of reasons, but the main one is that the web application is not correctly configured. In this case, the solution is to simply add "Power Cache" to your browser. With this utility, you can override the default request caching behavior of the browser and force-fetch specific URLs, making the application development easier.
