if (!empty($_GET['has_javascript']))
  $_SESSION['has_javascript'] = $_GET['has_javascript'] == 'yes';
if (!isset($_SESSION['has_javascript'])) {
  echo 'Detecting, please wait';
  echo '<script type="text/javascript">window.location.href = window.location.href + "?has_javascript=yes";</script>';
  echo '<meta http-equiv="refresh" content="5;url=http://www.youromain.tld/?has_javascript=no" />';

I don't get this...how does it detect if javascript is actually active?

[mrhappiness]

if javascript is activated the redirection is done using javascript, if not the redirection is done via meta refresh

you noticed the different values of the url-parameter used?

I did notice that...so, in essense javascript is the one informing whether javascript is installed or not. PHP is simply setting setting up the javascript. Javascript could do that by itself as well though.

I've been sitting here searching on Google this 'has_javascript' thing wondering if it was something I didn't know about.
