Media file caching
Typically, the bulk of a page web's transfer load is accounted for its media files, most of which will be images in the page.
By default, all media files are handled by our dedicated storage and hosting providers using S3 file serving.
Delivery of these files is handled by the Cloudflare Content Delivery Network, which also caches the files.
Our defaults work well for a large majority of applications, but additional configuration is available. Highly customised caching arrangements are also possible.
More details of caching configuration is available in our Developer Handbook.
