Struct headers::Origin

source · [−]

pub struct Origin(_);

Expand description

The Origin header.

The Origin header is a version of the Referer header that is used for all HTTP fetches and POSTs whose CORS flag is set. This header is often used to inform recipients of the security context of where the request was initiated.

Following the spec, https://fetch.spec.whatwg.org/#origin-header, the value of this header is composed of a String (scheme), Host (host/port)

Examples

use headers::Origin;

let origin = Origin::NULL;

Implementations

source

impl Origin

source

pub const NULL: Origin
