<P>
Chunked transfer encoding and decoding is new in HTTP/1.1. It allows applications
to use persistent connections while not knowing the content length a priori
to the response header is generated.
<P>
Both the encoder and the decoder are of type
<A HREF="HTFormat.html#encoding">HTCoder</A> which is defined in the
<A HREF="HTFormat.html">Stream Pipe Builder</A>. This means that bot the
encoder and the decoder are registered dynamically and called by the Stream
Pipe Builder if required.
<P>
<B>Note</B>: These streams are <I>not</I> set up by default. They must be
registered by the application. You can use the default initialization function
<CODE>HTEncoderInit()</CODE> function in the
<A HREF="WWWInit.html">initialization interface</A>.
<P>
This module is implemented by <A HREF="HTTChunk.c">HTTChunk.c</A>, and it
is a part of the <A HREF="http://www.w3.org/Library/"> W3C Sample Code
Library</A>.
