   The MIME parser stream presents a MIME document with a header and possibly a footer. It
   recursively invokes the format manager to handle embedded formats like MIME multipart.
   As well as stripping off and parsing the headers, the MIME parser has to parse any
   weird MIME encodings it may meet within the body parts of messages, and must deal with
   multipart messages.
   
   This module is implemented to the level necessary for operation with WWW, but is not
   currently complete for any arbitrary MIME message.
   
   This module is implemented by HTMIME.c, and it is a part of the W3C Sample Code
   Library.

  MIME header parser stream
  
   This stream parses a complete MIME header and if a content type header is found then
   the stream stack is called. Any left over data is pumped right through the stream.

  MIME Header ONLY parser stream
  
   This stream parses a complete MIME header and then returnes HT_PAUSE. It does not set
   up any streams and resting data stays in the buffer. This can be used if you only want
   to parse the headers before you decide what to do next. This is for example the case in
   a server app.

  MIME Footer ONLY parser

  MIME 1xx Continue Header Parser

  Partial MIME Response parser
  
   In case we sent a _Range conditional GET_ we may get back a partial response. This
   response must be appended to the already existing cache entry before presented to the
   user. That is, first we load the cached object and pump it down the pipe and then the
   new data follows. Only the latter part gets appended to the cache, of course.
