Header Field Classification

[mnot@…]

RFC2616 classifies headers (e.g., general, entity, request, response), but these classifications are sometimes misleading and often misused.

E.g., request-headers are defined as

The request-header fields allow the client to pass additional information about the request, and about the client itself, to the server. These fields act as request modifiers, with semantics equivalent to the parameters on a programming language method invocation.

We should discuss whether or not these classifications are helpful, and alternative approaches (e.g., allowing more than one classification for each header, to allow them to be more specific).

See also #104.
