Vary
header, defined in RFC7231
The "Vary" header field in a response describes what parts of a
request message, aside from the method, Host header field, and
request target, might influence the origin server's process for
selecting and representing this response. The value consists of
either a single asterisk ("*") or a list of header field names
(case-insensitive).
Vary = "*" / 1#field-name
