QPACK field-section coding (RFC 9204), static table only.
This server advertises SETTINGS_QPACK_MAX_TABLE_CAPACITY = 0 and
SETTINGS_QPACK_BLOCKED_STREAMS = 0, which RFC 9204 §3.2.3 and §2.1.2 make
binding on the encoder: it may not insert into the dynamic table, so every
field line it sends is either a static-table reference or a literal. That is what lets the
whole dynamic table – insertion, eviction, the two instruction streams, and
the head-of-line blocking they can introduce – be left out rather than
written and never used. A field line that does reference the dynamic table is
therefore not merely unsupported but a protocol violation, and is answered as
RFC 9204 §2.2.3 requires.
Encoding is the mirror image and just as small: the exact (name, value) in
the static table when there is one, its name alone when only that matches,
and a literal otherwise. Nothing is Huffman-encoded – see super::huffman.
