Hello Scott,
You can find more info about Content Types here...
Section 14.17 of RFC 2616
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.17
Hmm, reading that gives me the impression that parameters are defined
when media types are registered, and aren't something we can add to
suit our needs. That links to this:
http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.7
Which says "The presence or absence of a parameter might be
significant to the processing of a media-type, depending on its
definition within the media type registry."
So the media type registry determines the significance of parameters
for that media type. In the text/html registry [1], for example, I
see "Optional parameters: charset". But in the audio/mpeg registry,
I see "Optional parameters: none". I couldn't find any discussion of
parameters specific to video/mpeg, but video/mp4 [3] also says
"Optional parameters: none", as does video/quicktime [4]. Microsoft
has, of course, used unregistered X- content types. So what exactly
does "Optional parameters: none" mean? It seems to suggest we don't
have the option of parameters on these content types, but maybe I'm
reading that too literally?
