LoadPolicyFile on xmlsocket problem

Question

Hi,
I have some strange problem regarding the security settings
in Flash Player. I'm using AS3 to connect to port 80 on my server.
Because this is only allowed after downloading a policy file, I'm
calling
Security.loadPolicyFile("xmlsocket://"+_httpServer+":20");
just before
socket.connect(_httpServer, _httpPort);
On my server I tell inetd to listen on port 20 and start the
following bash script after a connection has been established:
#!/bin/bash
read
printf '<?xml version="1.0"?><!DOCTYPE
cross-domain-policy SYSTEM "
http://www.adobe.com/xml/dtds/cross-domain-policy.dtd"><cross-domain-policy><allow-access- from
domain="*" to-port="80" /></cross-domain-policy>\00'
exit
My app doesn't work, though. I notice, that a connection is
opened to port 20 and that the policy file is sent to the Flash
Player. But then nothing happens. No exception, no error, and I'm
already using the debug version of the Player.
Has anyone already successfully established a socket
connection after loading a policy file from another port via
"xmlsocket://"? Or am I completely wrong with the way my bash shell
script is handling the connection? Any ideas?
Thanks in advance
Mycroft.

Answer 1

So I switched from XMLSocket to just plain Socket.
I have this now:
  var sock:Socket = new Socket();
            sock.addEventListener(IOErrorEvent.IO_ERROR, onIOError);
            sock.connect("localhost", 7778);
            sock.writeUTFBytes(xmlMsg);
            sock.flush();
But nothing gets transmitted unless I close the Flex app.
I don't get this. What seems to be a problem?
I read an API docs twice and it says that writeUTFBytes (or any other write methods) are just putting stuff in a buffer
the flush() is the one that signals that the buffer content needs to be sent.
I'm doing just that and still I get nothing on the other side unless I close the Flex app.
Any suggestion?
Thanks
