HTTP protocol supports local caching of static resources by
the browser. Most web pages include resources that change
infrequently, such as CSS files, image files, JavaScript files, and
so on. These resources take time to download over the network, which
increases the time it takes to load a web page. HTTP caching allows
these resources to be saved, or cached, by a browser. Once a resource
is cached, a browser can refer to the locally cached copy instead of
having to download it again on subsequent visits to the web page.
The advantage of caching is obvious:
the page load time for subsequent user visits is
reduced, eliminating numerous HTTP requests for the required
resources
the total payload size of the responses is reduced.
