Constant product_os_http::header::EXPIRES
source · pub const EXPIRES: HeaderName;
Expand description
Contains the date/time after which the response is considered stale.
Invalid dates, like the value 0, represent a date in the past and mean that the resource is already expired.
If there is a Cache-Control header with the “max-age” or “s-max-age” directive in the response, the Expires header is ignored.
