user can't conditionally request an object. It's the client (browser, proxy)
that should do that if it has non-expired version. Unless is is set up to
always fetch the conent.

refresh afaik means request to unconditional reloading of an object.

Ahm, true. But after object is expired, the browser/cache still may have it
in the cache and try to revalidate it...
