Query string vanishes on header("Location: ...") redirect

I'm trying to redirect my users to a URL which includes a query string: $the_url = $CFG->wwwroot."/DLC/includes/L1_accept_required.php?cid=".$course->id; //die ("URL = $the_url"); header('Location: '. $the_url); When I uncomment the die() command, the URL shows properly, e.g.: http://mysite.com/DLC/includes/L1_accept_required.php?cid=152 The script at the URL calls the variable cid with $_GET: $cid = $_GET['cid']; When I browse directly to the URL as echoed by the die() command, the value of cid is available to the script. However, when I do the redirect, the URL that shows up in the browser's location bar does not contain the query string. Thus, the script at L1_accept_required does not function properly. The annoying thing is that the redirect works properly everywhere else in the site. Can anyone give me insight into what might be going on? I've checked for rogue .htaccess files which might be doing some fancy URL rewriting, but found nothing. -- Richard S.
