I'm building a FlexBuilder3 app, and I'm trying to test socket connectivity and my Crossdomain server by calling "Security.loadPolicyFile('xmlsocket://localhost:843')", and the call seems to do nothing.
I use WireShark packet sniffer to moitor network traffic, and the loadPolicyFile(...) call generates no network traffic whatsoever; it doesn't connect to my crossdomain server at all.
By contrast, I can reliably telnet to the crossdomain server, see the connection reported at the server, issue a hand-typed <policy-file-request> command in the telnet session, and get the crossdomain file sent across the telnet session. Thus, I know that my crossdomain server is working fine.
I'm compiling with the FlexBuilder3 GUI, and the projectr's Properties|Flex Compiler|Additional Compiler Arguments:" set to "-use-network=true -locale en_US"
