- assume anything about the datatype.</p>
- <p>Use this callback function to generate dynamic web
- content dynamically. When a part of the page is generated, send the
- data back to the client through <c>deliver/2</c>. Notice
- that the first chunk of data sent to the client must at
- least contain all HTTP header fields that the response
- will generate. If the first chunk does not contain the
- <em>end of HTTP header</em>, that is, <c>"\r\n\r\n",</c>

+ <p><c>mod_esi:deliver/2</c> shall be used to generate the response
+ to the client and <c>SessionID</c> is an identifier that shall by used when
+ calling this function, do not assume anything about
+ the datatype. This function may be called
+ several times to chunk the the respons data. Notice that the
+ first chunk of data sent to the client must at least contain
+ all HTTP header fields that the response will generate. If the
+ first chunk does not contain the <em>end of HTTP header</em>,
+ that is, <c>"\r\n\r\n",</c> the server assumes that no HTTP
+ header fields will be generated.</p>
+
+ <p><c>Env</c> environment data of the request see description above.</p>
+
+ <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.
+ <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> 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.
