Struct hyper::header::IfModifiedSince [−] [src]

pub struct IfModifiedSince(pub HttpDate);

If-Modified-Since header, defined in RFC7232

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
