HTML5 is going to include the tag rel=”noreferrer” . This tag will strip out the referrer information. That is the browser will not detect the referrer page. Mark Pilgrim writes in Dive into HTML5

rel=”noreferrer” “indicates that no referrer information is to be leaked when following the link.” No shipping browser currently supports this, but support was recently added to WebKit nightlies, so it will eventually be showing up in Safari, Google Chrome, and other WebKit-based browsers

It’s only use I think would be for BlackHat forums who will not want the target webmaster to know his source of traffic.

What do you think its use would be? Write in the comments.
