If we were to adopt the rule (however qualified) that a broader set
of header fields are valid in the trailer, there would still be a
set that really need to be in the header. I'll throw out a list
based on wanting certain kinds of information before receiving the
body:
- fields that govern operation of the recipient directly such as
Upgrade, Expect, or Host
- fields that determine whether or not the body is needed at all,
such as Authorization, Range, and the If-* headers
- fields that are needed to render or interpret the body, such as
Content-*
Header fields which MUST NOT be sent in the trailer:
Transfer-Encoding
Upgrade
Authorization
Expect
Host
If-Modified-Since
If-Match
If-None-Match
If-Range
If-Unmodified-Since
Max-Forwards
Proxy-Authorization
Range
Content-Base
Content-Encoding
Content-Language
Content-Length
Content-Location
Content-Range
Content-Type
