CDN caching is a method of caching data on a CDN server. This method of caching is quite commonly used for static files such as HTML, CSS, Javascript and assets such as videos and images. Because CDN is distributed across the globe, all the files live closer to the user, so when a user tries to access your application, they do not need to reach the region your application is hosted in and instead, they can get the data from a server much closer.
CDN Caching is commonly used with SPA applications such as React or Vue.
