Karl Wright commented on CONNECTORS-254:
----------------------------------------
The --data-binary switch to curl causes it to use POST. Here's a bit of the
manpage:
--data-binary <data>
(HTTP) This posts data exactly as specified with no extra proâ
cessing whatsoever.
So, what happens when you use curl to post your zero-length file? Do you get
back a 400 response? Try using the CURL -vvv switch to see what it is doing.
If it comes back with a 200 OK response and not a 400, then either you or I
should try to do the same thing while Wireshark is capturing packets. If you
are using a Linux system, you could instead want to use tcpdump to do the
capture, and then examine the capture with Wireshark (on Windows). If this is
too confusing, now that I have a test case I can try to do this later today.
