You have probably just discovered chunked coding, which is a rather
annoying discovery. My conjecture is, that either you send a content
length header (this is wrong with chunked coding IIRC) or the authors of
JMeter have yet to discover chunked encoding. The second would mean your
module is behaving correctly.

Yes. That is more or less how chunked coding works. See
