Struct actix_web::http::header::Expires

source ·
pub struct Expires(pub HttpDate);
Expand description

Expires header, defined in RFC 7234 §5.3

The Expires header field gives the date/time after which the response is considered stale.

The presence of an Expires field does not imply that the original resource will change or cease to exist at, before, or after that time.

§ABNF

Expires = HTTP-date

§Example Values

  • Thu, 01 Dec 1994 16:00:00 GMT

§Examples

use std::time::{SystemTime, Duration};
use actix_web::HttpResponse;
use actix_web::http::header::Expires;

let mut builder = HttpResponse::Ok();
let expiration = SystemTime::now() + Duration::from_secs(60 * 60 * 24);
builder.insert_header(
    Expires(expiration.into())
);
