WordPress – Leverage Browser Caching with Plugin


To leverage your browser’s caching generally means that you can specify how long web browsers should keep images, CSS and JS stored locally. That way the user’s browser will download less data while navigating through your pages, which will improve the loading speed of your website. Let’s discuss a WordPress plugin that you can install to perform it. Be sure you have a recent, good backup of your site you can use to restore from if an update or upgrade goes horribly wrong.
