Comment on Useful custom 403 and 404 error pages with PHP by Sjan Evardsson

Very true, if you are not using the Apache built-in custom error page behavior. (Apache will set the proper headers when you are.)

In cases where you are using mod_rewrite to point everything to an app (like WordPress and others) you want to make sure that your error pages do set the proper error code in the header.

Don’t forget to include the error code in the header! A simple header(“HTTP/1.0 404 Not Found”) at the beginning of the custom 404 document would do.

If you’re using Parallels on Mac you can download a Chromium OS image directly from them. Very easy.

Comment on Apache and PHP HTTP PUT Voodoo by HTTP File Upload Libcurl - Page 2

[...] 1,797 You're trying to do an HTTP PUT to an Apache server. I don't believe that Apache supports PUT out of the box, hence the "Method not allowed" error. You need to properly configure Apache to support PUT. Here's one link to that end. [...]

Sure thing. This is a test script that just spits back your request. I am sure you can see how to extend this to pass the data through to your API. Cheers.

  $v)
		{
			if (substr($k, 0, 5) == "HTTP_")
			{
				$k = str_replace(' ', '-', str_replace('_', ' ', ucwords(strtolower(substr($k, 5)))));
				$headers[$k] = $v;
			}
		}
	}
	return $headers;
}
$verb = strtolower($_SERVER['REQUEST_METHOD']);
$data	= array();
switch ($verb)
{
	case 'get':
		$data = $_GET;
		break;
	case 'post':
		$data = $_POST;
		break;
	case 'put':
		parse_str(file_get_contents('php://input'), $put_data);
		$data = $put_data;
		break;
}

print <<

Thanks, Andrew. That should help those who wish to communicate in the multicast space.

In terms of aggregation I have not seen any noticeable difference in latency using the aggregate values (/4s) versus the non-aggregate (/8s). I would imagine that it makes the RESERVED_IPS file shorter, which may speed up startup times and possibly reduce iptables memory usage slightly.

That might be something to work out and add to the script as well …

Adding this to the Python script removes the multicast entries. With this addition the output is the same as the stock get-iana script except the IP's are not agregated meaning you may end up with several /8 networks instead of a /4. For example: 240.0.0.0/8 ... 255.0.0.0/8 versus 240.0.0.0/4 Here are the changes:

                    if k.localName == 'status':
                        status = k.firstChild.data
                    if k.localName == 'designation':
                        designation = k.firstChild.data
                if status == 'RESERVED' or status == 'UNALLOCATED':
                        if designation != 'Multicast':
                                results.append(prefix)
