Cannot connect to socket in same domain

I have a Flex web app (compiled to regular SWF) that tries to connect to a (binary, not XML) socket on its own server. So if the swf is at example.com/app.swf, 开发者_StackOverflowthe socket is example.com:12869

This should be possible, AFAIK, but when I try to connect I get a security error saying that example.com/app.swf cannot access example.com:12869.

Even though it shouldn't be needed, I also have a crossdomain.xml file containing

<cross-domain-policy>
<allow-access-from domain="*" to-ports="*"/>
</cross-domain-policy>

but it doesn't help.

What can I do?

You can see the app here.

You could use my Apache 2 module - it listens at the port 843 and answers socket policy requests

The thing is that by default Flash will request the policy from the socket, meaning it sends <policy-file-request/> to the Socket - if you have the possibility to add it to your server implementation, you can have a look at how that guy fixed the same sort of problem.

You can also use Security.loadPolicyFile("http://axa3.axastudios.nl/crossdomain.xml") before initiating the socket connection to force it to load your policy first. I'm not 100% sure if this works for Socket connections though, the docs (search for "Socket policy files") are slightly confusing.
