Struct actix_web::http::header::IfModifiedSince

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

If-Modified-Since header, defined in RFC 7232 §3.3

The If-Modified-Since header field makes a GET or HEAD request method conditional on the selected representation’s modification date being more recent than the date provided in the field-value. Transfer of the selected representation’s data is avoided if that data has not changed.

§ABNF

If-Unmodified-Since = HTTP-date

§Example Values

  • Sat, 29 Oct 1994 19:43:31 GMT

§Examples

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

let mut builder = HttpResponse::Ok();
let modified = SystemTime::now() - Duration::from_secs(60 * 60 * 24);
builder.insert_header(
    IfModifiedSince(modified.into())
);
