Remarks
Purely a caching hint that saves a browser from repeating the preflight before every request. It does not permit an origin: which origins are allowed is decided by the channel's own origin check, which admits only an absent origin, localhost and 127.0.0.1 and cannot be widened by any property. A longer lifetime here never grants access that was not already granted.
Set it to zero or less to leave the hint out and have the browser preflight each time.
