Hello Ryan,

May I ask an very stupide question, what do you mean by nginx is not supported back-end keep-alive?

I checked with wireshark, both NTLM and MD authentication are using the same TCP connection, as far as I understand, nginx is just do a forward job, so the question is that why nginx could foward the MD request to the client but not NTLM request?

I hope my dull mind will not bother you so much :-)

Many thanks in advance!
