Struct uiuifree_actix_web_util::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.
