Backend keepalive http connections are supported since nginx 1.1.4, but
it doesn't help to proxy NTLM. See below.

NTLM is connection-based and requires the same connection to be
used for other requests from the client. It's not going to work
through http proxy servers as "the same connection for the same
client" isn't guaranteed by http proxy servers. See here for
Digest authentication, in contrast, doesn't rely on the same
connection to be used. Instead, client provides data originally
supplied by the server (nonce value) in each request. See here
