Which header field to use for entity author/contact.

I've been trying to determine the recommended way of returning the entity
author/contact in the HTTP response.

The HTTP 1.0 draft provides one method using the LINK entity header and
its rev "attribute" [1].

The HTML 2.0 draft documents an example using the <META> tag which uses
'Reply-to' as the value of the http-equiv attribute [2]. However, I can't
find this header documented in HTTP/1.0. (The same incidentally also
goes for 'Keyword' which is used in the same example).

A thread from the start of April in the hypermail archive of the HTTP-WG
mailing list also mentions using 'From' [3].

Which should I use, or is there another alternative?

Thanks for your help,


P.S. The HTML draft clearly states that the server MAY read the document
<HEAD> to generate header fields. Do any servers currently do this?
(I'm reasonably certain the CERN httpd does not - although the meta
data file can be used to the same end).
