+ several times to chunk the the respons data. Notice that the

+ all HTTP header fields that the response will generate. If the

+
+ <p><c>Input</c> is query data of a GET request or the body of
+ a PUT or POST request. The default behavior (legacy reasons)
+ for delivering the body, is that the whole body is gathered and
+ converted to a string. But if the httpd config parameter
+ <seealso
+ marker="httpd#max_client_body_chunk">max_client_body_chunk</seealso>
+ is set, the body will be delivered as binary chunks
+ instead. The maximum size of the chunks is either <seealso
+ marker="httpd#max_client_body_chunk">max_client_body_chunk</seealso>
+ or decide by the client if it uses HTTP chunked encoding
+ to send the body. When using the chunking
+ mechanism this callback must return {continue, State::term()}
+ for all calls where <c>Input</c> is <c>{first,
+ Data::binary()}</c> or <c>{continue, Data::binary(),
+ State::term()}</c>. When <c>Input</c> is <c>{last,
+ Data::binary(), State::term()}</c> the return value will be ignored.</p>
+ <note><p>Note that if the body is
+ small all data may be delivered in only one chunk and then the
+ callback will be called with {last, Data::binary(), undefined}
+ without getting called with <c>{first,
+ Data::binary()}</c>.</p></note><p>The input <c>State</c> is
+ the last returned <c>State</c>, in it the callback can include
+ any data that it needs to keep track of when handling the chunks.
