  # Rack folds a genuinely repeated header (Tina4::Response#to_rack only
  # ever repeats Set-Cookie, joined "\n" — the Rack 2/3 convention for a
  # multi-value header carried in a single hash slot) into ONE value; a
  # header value can never legitimately contain a raw newline (RFC 7230),
  # so splitting on "\n" is safe and general, not a Set-Cookie special
  # case. @header_list keeps every occurrence, in emission order, so a
  # duplicate is assertable via get_all(); @headers stays the back-compat
  # single-value view — the LAST occurrence, the "last wins" contract the
  # other three frameworks converge on — so nothing that reads a plain
  # (never-repeated) header sees any change (TC-HEADER-COLLAPSE,
  # TC-DEC-02).
  @header_list = {}

Instance Method Details

#get_all(name) ⇒ Object

Every value sent for name (case-insensitive), in emission order.

A header sent once returns a one-item array; a header never sent returns an empty array. This is the one place a duplicate response header (two Set-Cookie) is visible — headers always collapses to the LAST value, same as before (TC-HEADER-COLLAPSE, TC-DEC-02).
