Cross domain policy files, secure servers, and loads from virtual directories

Two unique issues regarding cross domain policies.

First, in regards to connecting via https://, if you are connecting from a non secure environment, the domain in question must have '-secure="false"' appended to it, for example:

<?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="*.yourinsecuredomain.com" secure="false" />
</cross-domain-policy>

Second, virtual directories...typically your cross domain file is loaded into the root of the server. You'll still need to do that. However, you will need a duplicate cross domain file at the virtual directory level as well. Load the domain root file via Security.loadPolicyFile("http"//www.yourdomain.com/crossdomain.xml"). The second policy file at virtual directory root level does not need to get loaded the same way, however it is checked for automatically when loading the actual content.
