Freeware local proxy engine for Windows? [closed]

"In the past when I needed a proxy to allow a screenscraping script to talk to corporate servers that require NTLM authentication, I downloaded NTLM Authorization Proxy Server and it worked very well. You can get version 0.9.9.6 here.

I don't believe that it runs in the system tray, however you could try using SRVANY to change it into a service.

The only other way that I know which might work is curl but I'm not sure if this can just function as a general proxy. Go to the curl man page and scroll down to --proxy-ntlm"
