Jan Ypma commented on OLINGO-272:
---------------------------------
This is not fixed in 4.7.1, when using OLingo with NTLM authentication. NTLM
requires every request to be sent at least 2 times (3 if discovering NTLM is
used). The first request always yields an NTLM challenge from the server, which
must be hashed into the authentication token of the second request.
That's very unfortunate for PUT, PATCH and POST of course, since it requires to
send the body twice. I actually don't know if the first request could be sent
without body, though.
Either way, with NTLM, a quick fix in OLINGO could be to wrap the created http
entity in a {{BufferedHttpEntity}}, so it can be sent twice.
