Line 21 in prepend.php is the final line in this block:

$request = quercus_servlet_request();
$contextPath = $request->getContextPath();
$host = $_SERVER["SERVER_NAME"];
$port = $_SERVER["SERVER_PORT"];
$site_base_url = "http://$host:$port".$contextPath."/php/store"; [^]

sorry, I couldn't reproduce this with resin pro 4.0.18 and the latest trunk.

Could you please verify this by using the attached test file?
Also please make sure, that the problem does not originate by
one of your filters by creating a empty web-application and trying it there.

You have at least 4 filters in your webapp that "could" mess with the HttpServletRequest. Please check them.

Hello Dominic,
Since upgrading to 4.0.18 and adding pro.jar, this issue seems to be resolved. If it reappears I'll return to the issue.

Thanks,
Andrew.
