I have a question regarding this answer by the author of curl:
http://stackoverflow.com/a/1848947

I have the following test web server:

while [ 1 ]; do echo "HTTP/1.1 200 OK
Content-Type: text/plain
Date: Sat, 04 Jan 2014 15:14:04 GMT
Connection: keep-alive
Transfer-Encoding: chunked

b
Hello World
0
" | nc -l -p 8000; done;

to test the behavior of a client (written with pycurl).

However, curl gives me the following error message:

$ curl -ivs localhost:8000
* Rebuilt URL to: localhost:8000/
* Adding handle: conn: 0x1f4ecc0
* Adding handle: send: 0
* Adding handle: recv: 0
* Curl_addHandleToPipeline: length: 1
* - Conn 0 (0x1f4ecc0) send_pipe: 1, recv_pipe: 0
* About to connect() to localhost port 8000 (#0)

Firefox, links and lynx can correctly display the message.
w3m shows the size of the chunks too:
"
b
Hello World
0
"

My question is, is there something wrong with the http response (and the
clients can still handle it) or is there an issue with the handling of the
chunked requests in curl.

Thanks.
