title: PHP redirected page doesn't have a referral url
body: <p>I have two site <code>sitea.com</code> and <code>siteb.com</code> </p>
  
  <p>I need to redirect pages from <code>sitea.com</code> to <code>siteb.com</code>. The redirect script in <code>sitea.com</code> is</p>
  
  <pre><code>&lt;?php
  header("Location: http://siteb.com/somepage");
  ?&gt;
  </code></pre>
  
  <p>The redirection is taking without any flaw. The functionality if fulfilled. But I have google analytics tracking on siteb.com which should show that the source is referral from sitea.com</p>
  
  <p>I dug into web developer tools in google chrome and found that <code>siteb.com</code> doesn't send a referral header in the request. </p>
  
  <p><strong>How do i redirect my visitors from <code>sitea.com</code> to <code>siteb.com</code> which sends the referral headers on <code>siteb.com</code>.?</strong></p>
