Flash doesn't connect to socket even though policy allows it
- by Bart van Heukelom
In my Flash app, I'm connecting to my server like this:
Security.loadPolicyFile("xmlsocket://example.com:12860");
socket = new Socket("example.com", 12869);
socket.writeByte(...);
...
socket.flush();
At port 12860 I'm running a socket policy server, which (according to this document) correctly serves up my policy like this:
00000000 3c 70 6f 6c 69 63 79 2d 66 69 6c 65 2d 72 65 71 <policy- file-req

I get no security warnings, which I used to get before the policy server was in place.
Still, the connection to port 12869 doesn't work. It's made (I can see with Wireshark and on the server), but no data is sent by Flash.
It might be worth knowing that the SWF itself is served from example.com as well.
