Understand how HTTP Caching works with max-age and etags.

HTTP Caching is used to fetch resources way faster and reduce server load at the same time. This is done by both having the browser reusing assets instead of making a network request, and by placing a CDN with edge locations that both serve resources closer to end users to reduce latency. CDNs also cache those assets to be able to respond to similar requests without making a network call to the origin server. This is achieved by the use of max-age and etag that are included in the headers of the response.
