Hide Referrer on click

Question

I want to hide the referrer when I click a link on my website. To understand better what I want to do: When somebody clicks a link on my website, I don't want the other website owner to know where the visitor came from.

I don't care if it's done by PHP, HTML or Javascript.

I tried with HTML refresh, javascript window.location, javascript popup, PHP header redirect, but nothing worked.

In addition to jimps' answer i created a one file .php solution that will work with both HTTPS and HTTP. It uses two steps (and so it will call anonym.php twice). First a javascript redirect, second a php header location redirect. I personally needed this to test posted urls from within an admin area. Enjoy!

<?php
  // anonym.php

  if ($_SERVER['QUERY_STRING']) {

    if (stripos($_SERVER['QUERY_STRING'], 'anonym2=') === FALSE) {
      echo '<script>document.location.replace("anonym.php?anonym2=' .$_SERVER['QUERY_STRING']. '");</script>';
    } else {
      header('Location: ' . str_replace('anonym2=', '', $_SERVER['QUERY_STRING']));
    }

    exit();

  }

?>

As of 2015 this is how you prevent sending the Referer header:

<meta name="referrer" content="no-referrer" />

Just add this to the head section of the web page. Works both for links and for Ajax requests.
