RFC 2616 3.5 Content Codings
https://www.rfc-editor.org/rfc/rfc2616#section-3.5

deflate
        The "zlib" format defined in RFC 1950 [31] in combination with
        the "deflate" compression mechanism described in RFC 1951 [29].

RFC 7230 4.2.2. Deflate Coding
https://www.rfc-editor.org/rfc/rfc7230#section-4.2.2

RFC 9110 8.4.1.2. Deflate Coding
https://datatracker.ietf.org/doc/html/rfc9110#section-8.4.1.2

The "deflate" coding is a "zlib" data format [RFC1950] containing a
  "deflate" compressed data stream [RFC1951] that uses a combination of
  the Lempel-Ziv (LZ77) compression algorithm and Huffman coding.

Note: Some non-conformant implementations send the "deflate" 
  compressed data without the zlib wrapper.
