We went with
Content-LengthConnection- and
Content-Type
but a few more noteworthy mentions that we won't care about for now are:
Content-Encoding: Is the response content encoded/compressed? If so, then this should be included to tell the client how to decode it. (Remember, encoded != encrypted)Date: The date and time that the message was sent. This is useful for caching and other things.Cache-Control: Directives for caching mechanisms in both requests and responses. This is useful for telling the client or any intermediaries how to cache the response.
