XML file not loading in FF from server

Question

I've created a web page that loads an external XML file and
then uses javascript code to parse the file for requested
information. I know it's not the best way to do this, but I'm
trying to get this working before I move on to "better" methods.
When I run the page using the "Preview/Debug in browser"
funtionality of DW everything works great both in IE and FF. But
when I load the page to the server and then load the page in a
browser, it works in IE but not in FF. It looks as though FF is
just not loading the XML file. I can't figure out why the page
would work if launched from DW, but not work if the page is loaded
on the server and then run from there, and only in FF.
The code I'm using to load the XML file is supposed to be
cross-browser compatible. I've seen many versions like from various
sources, so it should be OK. I'm pretty new to all of this so I'm
hoping that I'm just missing something simple. Does anyone have any
idea why this is behaving this way?
Thanks for any help.

Answer 1

so, in frame 1 of your fla before you execute that cross-domain load method, use:
System.security.loadPolicyFile("http:www.yourcrossdomain.com/subdirectoriesIfNeeded/crossd omain2.xml");
where the following (crossdomain.xml) is in www.yourcrossdomain.com's root (IF you want to allow allow subdirectory policy files):
<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<site-control permitted-cross-domain-policies="all"/>
</cross-domain-policy>
and in the subdirectory (and its descendents) that you want to allow access put crossdomain2.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="www.thedomainthatstryingtoloadcrossdomaindata.com" />
</cross-domain-policy>
