RE: how to send http response in several chunked package with Tomcat
Hi Filip,
Yes it works. Thanks a lot!
Christopher, in fact I'm writing a servlet to fool a management
software, So I need make sure the servlet response is as close to real
device as possible.
Thanks for everyone's help.

you don't need to do that, tomcat does it for you.
all you need to do is
while (havedata) {
response.getOutputStream().println(some data)
response.flushBuffer()
}

I created two http chunk successfully by this way. The first chunk is
the data which wraps tmp, the second is the end chunk.
But the question is, all these chunk and http header are in same frame
(get it from wireshark.).
How can I put them in different frame?
Which means we need 3 frame for the case: the first frame will carry
the http header, the second will carry the first chunk data, the last
frame will carry the end chunk.
Does it mean I need control the tcp/ip protocol? It's impossible,
right?

Hi Johnny,
Thanks a lot. I read the http RFC and find something like this:
The chunk-size field is a string of hex digits indicating the size of
the chunk. The chunked encoding is ended by any chunk whose size is
zero, followed by the trailer, which is terminated by an empty line.
Do u have any tutorial of ChunkedOutputFilter? I can't find anything

Hi all,
Is there a way to make tomcat generate http response in
chunked-encoding style?
suppose I have a file resp.log and I can parse it in byte[], how can I
send the byte array in several chunked package?
Hanks I have just started looking at this, so no expert but I did
notice
ChunkedInputFilter,ChunkedOutputFilter
I think your answer is in setting a filter in normal Http I notice
that chunking happens automatically if header size ommited, but with
so much control of the socket I think you have to pump it thru a
filter and then there must be a way to say last chuck... and start
chuck...
Short of that one would have to set headers themselves and add
trailing 0's and end sequences, so I think those classes are specific
to http11
a guess
Any suggestion is welcome!
Thanks

RE: how to send http response in several chunked package with Tomcat
Hi Filip,
Seems the method has a problem : tomcat puts the http header and part of
the body in the same chunk.
But I hope to generate the response in below format:
Suppose I need use String tmp as the response, tmp = part1 + part2 +
part3+part4;
we use 4 tcp frame totally for the http response:
Frame 1: only carry the httpheader, no chunk in the frame
Frame 2: includes the first chunk, carries part1+part2;
Frame 3: includes the second chunk, carries part3+part4;
Frame 4: includes a chunk whose length is 0, tells client it's the end
of chunks;
However Tomcat generate the response in such way:
Frame 1: includes httpheader and the first chunk, 1st chunk carries
part1;
Frame 2: includes part2 + part3;
Frame3 and Frame4 are same with above;
So how can I make sure there is only http header in the first frame?
Thanks.

Hanks I have just started looking at this, so no expert but I did notice ChunkedInputFilter,ChunkedOutputFilter I think your answer is in setting a filter in normal Http I notice that chunking happens automatically if header size ommited, but with so much control of the socket I think you have to pump it thru a filter and then there must be a way to say last chuck... and start chuck... Short of that one would have to set headers themselves and add trailing 0's and end sequences, so I think those classes are specific to http11 a guess Any suggestion is welcome!

RE: how to send http response in several chunked package with Tomcat
Hi Johnny, Thanks a lot. I read the http RFC and find something like this: The chunk-size field is a string of hex digits indicating the size of the chunk. The chunked encoding is ended by any chunk whose size is zero, followed by the trailer, which is terminated by an empty line. Do u have any tutorial of ChunkedOutputFilter? I can't find anything from its API document..
