[AS3] Binary Socket & Policy Files

I need to connect a socket server to a flash client through port 80, but since some proxies only allow http data through the port and the flash client just sends a <policy-file-request/> (no http headers) the request would simply bounce.

I made an app that servers both the swf and the socket conntection from the swf, but it still requires a policy file. :confused:

So, is there anything that i can do to make this work?
