In order to load data from external domains that do not host a crossdomain.xml file (like zoho creator)you should create a proxy file in your server folder hosting the swf file:
loadXML.php
<?php
$dataURL = “http://yourexternalURL”;
readfile($dataURL);
?>
then you’d include the crossdomain.xml
<?xml version=”1.0″?>
<!DOCTYPE cross-domain-policy SYSTEM “http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd”>
<cross-domain-policy>
<allow-access-from domain=”*”/>
</cross-domain-policy>
now you are ready to go!
