loadPolicyFile doesn't appear to send the request when using xmlsocket://

Hi,

I’m stumped with a strange problem from Flex Builder (and Flash Player in general). I’m trying to enable a socket connection in my dev environment. The newer players (version 9.0.124.0 and above) require an XML socket policy file to be served, ideally from port 843.

I’ve set up and verified the socket server, it appears to be solid, the problem I’m having is that my Flash Player doesn’t appear to make the request. I’m explicitly asking for permission with:

Security.loadPolicyFile("xmlsocket://widget.localhost:843");

But there’s no connection to my socket server and no record of a failed request in policyfiles.txt.

Anyone run into something like this before?

Some of the resources I’ve accessed while troubleshooting this are:

Thanks.
