I can only reproduce that behavior with chunked encoding, as expected.
Each chunk is separate. Turn on verbose mode and check for chunked encoding.
while true; do perl -e 'print ("HTTP/1.1 200 OK\r\nTransfer-Encoding:
chunked\r\n\r\n3\r\nFOO\r\n3\r\nBAR\r\n0\r\n\r\n")' | nc -4l localhost
8000; done
