    OK, multipart/xyz is just like any other MIME media type - as far
    as the client is concerned, it is getting one big file of type
    "multipart/xyz", which can then be parsed to get the individual
    pieces. A chunked response might look like this:

        Content-Type: multipart/related; boundary-string="---FOO---"
        Transfer-Encoding: chunked

        B
        ---FOO---

        1f
        Content-Type: application/ipp

        <some length>
        <ipp message>

        B
        ---FOO---

        1f
        Content-Type: application/ipp

        <some length>
        <ipp message>

        ...

        0

    Technically the chunking is part of the transport protocol and
    the multipart/related is a different content type which must be
    parsed separately from the HTTP data.
