NTLM / NTLM Session Response / NTLMv2 authenticating HTTP proxy
Cntlm is an NTLM/NTLMv2 authenticating HTTP proxy. It takes the address of your proxy or proxies host1..N and port1..N and opens a listening socket, forwarding each request to the parent proxy moving in a circular list if the active parent stops working. Along the way, a connection to the parent is created anew and authenticated or, if available, previously cached connection is reused to achieve higher efficiency and faster responses. When the chain is set up, cntlm should be used as a proxy in your applications. Cntlm also integrates transparent TCP/IP port forwarding tunneling through the parent incl. authentication.
