Q: How long do public links stay cached?

Images : Cache-Control: public, max-age=31536000, immutable (a year). Other files : Cache-Control: public, max-age=60, must-revalidate . Visibility is checked on every request to the public hosts, and edge-cached parts are only served after that check, so making a file private stops new requests right away. Copies already saved in a viewer's browser may remain: up to 60 seconds for files, longer for images. Learn more Public files Set file visibility
