Question

I’m creating a client-server game. My client is a flex based game, and my server is erlang server.
At the beginning, when I test directly my flex client in flash player, I can establish a connection easily to my erlang server through socket connection. And both can exchange data with no problem.

The problem rise when I deploy my flex app at Apache http server, and running it using a browser by calling http://localhost/ … my flex socket sends message requesting for a crossdomain policy to my erlang server.

So I create an xml message that represent a crossdomain policy, and send it back to my flex app as a response for that request.

Yet still I can’t establish any permanent socket connection between my flex client and my erlang server. I know this because I add listener on my flex socket that will modify its internal state to CONNECTED, if a connection between client-server has established.

Answer 1

I haven’t experienced the problem but maybe this would help.

The default policy file is named
crossdomain.xml and resides at the
root directory of the server that is
serving the data…
You can use the loadPolicyFile() method to access a nondefault policy file.

A policy file served by an XMLSocket
server has the same syntax as any
other policy file, except that it must
also specify the ports to which access
is granted. When a policy file comes
from a port lower than 1024, it can
grant access to any ports; when a
policy file comes from port 1024 or
higher, it can grant access only to
other ports 1024 and higher.
