Constant http::header::ACCEPT_RANGES

pub const ACCEPT_RANGES: HeaderName;

Marker used by the server to advertise partial request support.

The Accept-Ranges response HTTP header is a marker used by the server to advertise its support of partial requests. The value of this field indicates the unit that can be used to define a range.

In presence of an Accept-Ranges header, the browser may try to resume an interrupted download, rather than to start it from the start again.
