Expand description
Header field names (RFC 3261 §7.3, §20).
Names compare case-insensitively, and a compact form is the same header as its long form.
Both facts are load-bearing: RFC 4475 §3.1.1.1 spells Max-Forwards as MaX-fOrWaRdS and
writes Content-Length as l and Subject as s in the same message.
Resolving a name does not lose the original spelling. The entry that holds a header keeps the bytes as they arrived so a forwarded message is re-emitted unchanged; this type is only how the meaning of a name is decided.
