Xml.send() works but not sendAndLoad()

Question

Hi guys, i'm trying to send data to a servlet ( which is
hosted on a different server and managed by a 3rd party so i can't
change it)
When I use the following code:
requestXML.send ("
http://www.mydomain.com/xmlpost",
"_blank","POST");
it opens a new browser window which displays the xml
response. All good.
But I don't want a new broswer window. I want the flash to
wait and see what the response is. So I use:
requestXML.sendAndLoad ("
http://www.mydomain.com/xmlpost",
myLoginReply_xml,"POST");
var myLoginReply_xml : XML = new XML ();
myLoginReply_xml.contentType = "text/xml";
myLoginReply_xml.ignoreWhite = true;
myLoginReply_xml.onLoad = myOnLoad;
function myOnLoad(success:Boolean) {
if (success)
getURL ("javascript:alert('" + myLoginReply_xml + "')")
} else
getURL ("javascript:alert('FAIL!')")
And nothing happens.
Is there any difference between send and sendAndLoad why it
wouldn't work? Different security parameters, different dtat
format, anything?
Thanks!

Well that didn't do it. Further investigation brought the
following facts:
If i test from the flash environment, Flash doesn't ask for a
crossdomain.xml and the request is made ( i get an entry in the
database) and the response sent, but Flash doesn't pick anything up
and the reply XML.onLoad event never fires.
If I test from a dev server, flash looks for the
crossdomain.xml file, but even though it finds it and the servers
are allowed to communicate, the request never gets sent (no entry
in the database)
Arrrrgg I'm pulling my hair over this!
Anyone able to help ?
Thanks.
