What is the most reliable way to hide / spoof the referrer in JavaScript?

Question

Normally, the referrer is traceable through:

• JavaScript\'s document.referrer
• The request headers, e.g. PHP\'s $_SERVER[\'HTTP_REFER

Answer 1

what if we submit a FORM using JavaScript, this way there will be no referrer.

document.form_name.submit()

basically we are submit a form with desired ACTION method.
