Cross-domain Security

In Flash Player 9.0.115.0 and up, Adobe has added new strictness to the way it handles cross-domain security. If you have one .swf file trying to access a .swf on another domain, that other domain must have a crossdomain.xml file located at its webroot, otherwise the request will fail. In our case, when Bingo loads, it may try to access files located on a separate server or retrieve transaction data from the gameserver. If a crossdomain.xml file is not found, or otherwise determined to be invalid, the application may behave erratically eg. may not get past the loading screen.
