Cntlm is an NTLM / NTLMv2 authenticating HTTP/1.1 proxy. It caches auth'd connections for reuse, offers TCP/IP tunneling (port forwarding) thru parent proxy and much much more. It's in C, very fast and resource-efficient. Go to http://cntlm.sf.net/

Project Samples

Speed comparison, CNTLM vs. NTLMAPS. Behold conn. reuse! :) Resource consumption, the same proxies.

    It doesn't support PAC proxy scripts, crash often (in Windows) and has no GUI. I find Corporate Proxy Helper (www . corporateproxyhelper . com) to be much better

    Very useful. It works under Windows 7 but it hangs every now and then and needs manual restart.
