Hi Johnny, I try below method implement the chunk in code:
String tmp = "something very long"; String hlen = Integer.toHexString(tmp.length()); hlen = hlen +"\r\n" + tmp.toString(); String chunkend = Integer.toHexString(0)+"\r\n"; response.getOutputStream().println(hlen); response.getOutputStream().println(chunkend); 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?

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..

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!
