I have a Kiosk that connects to a local socket server so it can access some hardware. If the kiosk code is stored locally, it can access the socket perfectly.

However, and I know for good reason, if the kiosk code is hosted on a remote server, it can not access the local socket server because of a sandbox violation.

The problem is that all of these kiosks are hosted on AppEngine, so when I am done making changes, it takes hours to render out to a single HTML file, and change all the css/js location links.

Is there anyway possible for the allow the SWF file to access the local socket server when it is hostel remotely?

Also,
The socket server is a Java app that I dont have the source to. I run it locally through the terminal

    I’ve had the same problem.

    The thing is that with Flash player 10 security with sockets has become much stricter. Just placing crossdomain.xml on the server won’t do anything – you actually have to send the crossdomain policy file to any client who connects.

    The simplest solution is provided by Adobe – they’ve provided a couple of scripts, one perl and one python, which will set up a policy file server. You can find them here:
