Continuos connection with AS3 in browser (HTTP tunneling)

Oops, I lied a bit. The content type is hard-coded. But you can update that
to suit your needs (and I believe PHP comes with automatic MIME type
detection).

Hi RobDan75,

The short answer is, no. If your application is making calls across
domains, a crossdomain XML file will always be requested. If it's not there
or doesn't allow communication, Flash will stop trying to communicate with
that server. It would be a very severe security violation (in many respects)
for Adobe to allow this sort of thing. That being said, if you have access
to your own server, you can create a secondary proxy that will shuttle data
to and from the target proxy. Basically, it simply acts to send data to/from
Flash and the target server. Using PHP, simple HTTP requests are very simple
to carry out. Here's a script I used on an older project that did just that:

<?
if (isset($_POST['address'])) {
$address=$_POST['address'];
$proxyData=file_get_contents($address);
$fileSize=strlen($proxyData);
header('Content-Type: text/html');
header("Content-Length: " .$fileSize);
header("Cache-Control: no-cache, must-revalidate");
header ("Date: ".date("r"));
header("Expires: Mon, 01 Jan 2007 00:00:00 GMT");
header("Host: ".$_SERVER['HTTP_HOST']);
header("Server: Proxy Script v1.0");
echo ($proxyData);
} else {
echo ('You didn\'t include the data in the "address" variable.');
}//else
?>

Note that Flash needs to send an "address" POST variable telling the script
the address to load from. You can update this to GET if you want...it can be
used to test via the browser. This just makes it a bit more difficult to
abuse. The script automatically detects MIME type so you can use this to
transport any type of data (video, text, audio, etc.)
