Hi all,

We've been using HAProxy internally for a few years now, we've got a pair of Ubuntu boxes (VRRP between them) infront of a selection of identical IIS boxes,
hosting our business apps, CRM, HR, intranet etc.

I've added a new site onto the web servers, this is the first one that uses NTLM to authenticate users without them logging in. Using Internet Explorer if I connect direct to a server it works, but when I going via HAProxy no page
is returned.

I ran Ethereal on one of the web servers to see what was happening and saw the
client and server negotiate via HAProxy, after negotiation was complete IE sent
"Connection: Keep-Alive\r\n".

When I turned keep alive off in IIS and tried connecting direct it failed too,
am I right in presuming as HAProxy doesn't support keep alive NTLM won't work?
