On July 14, 2012, Matthew Prince announced that Cloudflare now supports single file purge, allowing users to clear the cache of a specific URL without affecting other cached files. Previously, users could only purge their entire cache or wait for it to expire. The new feature is available to all Cloudflare users and can be accessed via the API. Developers are encouraged to create systems that automatically update Cloudflare's network when files on a server have been updated, ensuring the latest copies are fetched.
