title: redirect tag and $_SERVER['HTTP_REFERER']
body: <p>I have one index.html with redirect,  (javascript, meta or php its the same problem) to other server.</p>
  
  <p>The html redirects to an external index.php where i have to print/echo -> parse_url($_SERVER['HTTP_REFERER'], PHP_URL_HOST) </p>
  
  <p>If I open the url with index.html it redirects and prints http_referer fine but if I open url directly, like <a href="http://portal-iso9001-2015.com/" rel="nofollow">http://portal-iso9001-2015.com/</a> (without index.html) it redirects but it does not print the http_referer.</p>
