Hey dude, i came up with this problem and got stucked with no straigth answer on what could preventing my flex app to do this kind of access. So THANK YOU SO MUCH! It helped a LOT. Very well writed article.

About the reconnect, you could use a keepaliveloop to keep connected an prevent reconnect:
/* create and start the keepalive */
keepAlive = new Timer(100000);
keepAlive.addEventListener(TimerEvent.TIMER, onKeepAliveLoop);
keepAlive.start();

/* define handle function */
private function onKeepAliveLoop(evt:TimerEvent):void {
connection.sendKeepAlive();
//Alert.show(”keepalive ” + getTimer());
}

This works well for me.

Thanks for this information Graham. I was particularly interested in your auto-reconnect code. I added it to my error handler and then went into debug mode.

Problem was that I never see (and have never seen) an error code 503 in my app, which would trigger this auto reconnect.

My question is: what triggers a 503 error? Based on the explanation above I would imagine it to be when the internet connection is interrupted to the client. However when I unplug my machine from the network no error gets triggered or anything

So I am trying to figure out what generates the 503, but more importantly, how to reliably auto-reconnect when things go wrong.

[graham] It’s dispatched in XMPPConnection.as, when it gets an IOError on the underlying socket. It should fire when you unplug your network cable, unless your XMPP server is local! Maybe it sends a DisconnectionEvent instead.

[...] There is an XMPP library for Flex, called XIFF. I’ve blogged some documentation about using XIFF. [...]

Thanks Graham, I haven’t tested to make sure your comments helped, but that is a very well-written article on how to set it up and the specific problem I was having — the security sandbox violation — is covered right away in the “Permission to connect” section.

And since the other posts on your front page are on Python, Flickr, Gallery2, and unit testing, you have a new subscriber.

Side note: two + four = six, not 6.
