Thanks, I am using the latest version of httpclient - 4.3.2-SNAPSHOT
By the way, below are the logs from the web server; it seems that the first two

don't have a user name in the request.

RE: connection closed on first attempt to send to IIS WebDav server
Oleg,
I managed to make the error go away by using "pre-emptive authentication" on
the client:
" When enabling preemptive authentication using
Sardine.enablePreemptiveAuthentication(String host), sending an authentication
header before any challenge received by the server."
Thanks so much for your help,
Aaron

I still think the culprit is Microsoft-IIS/7.5. It rejects the first
request as unauthenticated, which is fine, but it also closes the
connection without properly informing the client (by sending a HTTP/1.1
message without 'Connection: close' header).
Preemptive authentication helps work the problem around.

RE: connection closed on first attempt to send to IIS WebDav server

It rejects the first request as unauthenticated, which is fine, but it also closes the connection without properly informing the client (by sending a HTTP/1.1 message without 'Connection: close' header). Preemptive authentication helps work the problem around. Yes, I think you're right. Sadly, IT insists on using IIS, so I am stuck with this behaviour. The workaround doesn't add too much overhead, so I guess I will use it.
