Struct actix_web::http::header::IfUnmodifiedSince
source · pub struct IfUnmodifiedSince(pub HttpDate);
Expand description
If-Unmodified-Since
header, defined
in RFC 7232 §3.4
The If-Unmodified-Since
header field makes the request method
conditional on the selected representation’s last modification date
being earlier than or equal to the date provided in the field-value.
This field accomplishes the same purpose as If-Match for cases where
the user agent does not have an entity-tag for the representation.
§ABNF
If-Unmodified-Since = HTTP-date

§Examples
use std::time::{SystemTime, Duration};
use actix_web::HttpResponse;
use actix_web::http::header::IfUnmodifiedSince;
let mut builder = HttpResponse::Ok();
let modified = SystemTime::now() - Duration::from_secs(60 * 60 * 24);
builder.insert_header(
IfUnmodifiedSince(modified.into())
);
