Security sandbox violation when connecting to Socket from flex

Question

I am using a Socket (not xmlSocket) connection between flex applications and the server pushing messages.

Now, when I connect from the local machine to the server everything is working file and running, connection is succesful and I get data back and forth.

When I upload the application (flex) to the server and run it from there, I get a security sandBox violation message.

Note: 1. I do have a crossdomain file with * wildcard both on port and on domain. 2. I created a Securiy.allowDomain("*") as well.

Another thing. I also created another listener on that same server, listening to connections for port 843 (default) and this service just waited for a connection send policy file to the client and that's it.

That did not solve the problem as well...

That's next? What should I do to fix the problem?

Appreciate your help.

Answer 1

The fix for this issue was a dedicated policy file serving server. I implemented a socket listening to the dedicated port where flex is looking for policy file, once I got a connection and a request I answered right back with the appropriate policy file.

This solved the problem for all users and is working very well for me.

Thanks

Answer 2

did you try Security.loadPolicyFile ? Does your server on port ever actually 843 receive policy file requests (that's a tiny XML sent to request the crossdomain policy file)? Does your actual server ever receive policy file requests? What traffic do you get on your server?

    .NET
    Add crossdomain.xml to your Web server root directory, for example, 
C:\inetpub\wwwroot.

    Java
    Add crossdomain.xml to \ArcGIS\java\web_output, for example, 
C:\Program Files\ArcGIS\java\web_output.
