that's correct, that's how it works. I'll go over the specs to see if this is not what it is supposed to do

I am using Comet for by directional communication between a native java client and a tomcat server. I noticed that when sending chunks to the Tomcat server over the request stream Tomcat does not like to receive a CRLF at the end of a chunk, it is only accepting the CRLF at the beginning of the following chunk. According to rfc2616 the CRLF should be at the end of each chunk: http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.6.1 For example tomcat likes this type of chunk to be sent: CRLF chunk-size CRLF chunk-data But it does not like this format: chunk-size CRLF chunk-data CRLF Tomcat basically fires a Comet Read event to the CometProcessor with the chunk data, but afterward fires an ERROR event with subevent type IOEXCEPTION. I have tested this with Tomcat 6.0.14 as well as the trunk (Dec 11th, 2007). Here is the sample code of a java client that connects to a simple CometEcho processor: Socket s = new Socket("localhost", 8080); OutputStream out = s.getOutputStream(); out.write(("POST /CometEcho HTTP/1.1\r\n" + "Host: localhost:8080\r\n" + "Transfer-Encoding: chunked\r\n" + "\r\n").getBytes()); out.flush(); boolean first = true; BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); while (s.isConnected()) { String line = reader.readLine(); //String chunk = (first?"":"\r\n")+Integer.toHexString(line.length())+"\r\n"+line; // tomcat only accepts this kind of chunk String chunk = Integer.toHexString(line.length())+"\r\n"+line+"\r\n"; // this format should work according to rfc2616 first = false; out.write(chunk.getBytes()); out.flush(); } I was wondering if someone could explain this, and if this is by design, or if I am using Comet incorrectly.
