Hi All !

The problem :
1. On client-side i have next script :

var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
var Response = new ActiveXObject("MSXML2.DOMDocument");
strxml = "SOME XML..."
xmlhttp.open("POST","http://host/script.php",false);
xmlhttp.setRequestHeader("Content-type","text/xml");
xmlhttp.send(strxml);
alert(xmlhttp.ResponseText);

2. When script.php starts the CONTENT_LENGTH is not null,
its value is NNN bytes.

4. Constructions like :

$fp = fopen("php://stdin","r");
$data=fread($fp,$HTTP_SERVER_VARS{'CONTENT_LENGTH'});
fclose($fp);
echo $data;

or

echo $HTTP_RAW_POST_DATA;

don't work. They return null :-(

4. In PHP.INI always_populate_raw_post_data = On

Anybody knows what's happened ?
