Struct spa_server::re_export::http::header::IfUnmodifiedSince [−]
If-Unmodified-Since
header, defined in
RFC7232
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

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