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.

    extern HTConverter HTMIMEConvert;

### 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.

    extern HTConverter HTMIMEHeader;

### MIME Footer ONLY parser

Parse only a footer, for example after a chunked encoding.

    extern HTConverter HTMIMEFooter;

### 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.

    extern HTConverter HTMIMEPartial;
