Xml relative link not working on server

I have a web application that doesn’t pull in the XML which is brought in from SwfObject 1.5 that has the xml location sent in via flashvars. The xml location is a relative link. You can see it here,

<script type=“text/javascript”>
var flashvars = {};
flashvars.xmlStatic = “…/xml/static2.xml”;
flashvars.xmlDynamic = “…/xml/dynamic2.xml”;
var params = {};
var attributes = {};
swfobject.embedSWF("_028_optisolutions.swf", “flashDiv”, “870”, “778”, “9.0.0”, “expressInstall.swf”, flashvars, params, attributes);

Everything works fine on my server, my local machine, but on my client’s server it is not working. Is there anyone that knows why their might be a problem loading dynamic content using relative urls? I’ve had this problem with loading flvs, jpgs and swfs before with as2 and as3. Cross-Domain Policy files maybe (but its not leaving the domain)?

Any help would be a life saver.
