For improved performance, Cloud 66 caches volatile code. It is possible for a those caches to become invalid if you switch branches, change git repository URL, rebase or force a commit. Since switching branch or changing git repository URL is done via the Cloud 66 interface, your volatile caches will automatically be purged. However, rebasing or forcing a commit is external to Cloud 66 and therefore doesn’t trigger the purge, so this command can be used to manually purge the existing volatile caches.
