The Art Of Scripting HTTP Requests Using Curl

If your proxy requires the authentication to be done using the NTLM method,

If you use any one these user+password options but leave out the password
part, curl will prompt for the password interactively.

7. REFERER
- A HTTP request may include a 'referer' field, which can be used to tell from
- which URL the client got to this particular resource. Some programs/scripts
- check the referer field of requests to verify that this wasn't arriving from
- an external site or an unknown page. While this is a stupid way to check
- something so easily forged, many scripts still do it. Using curl, you can put
- anything you want in the referer-field and thus more easily be able to fool
