flashsocket cannot connect in socket.io

Cancelled

Job Description

I am trying to use flashsocket in socket.io, but it has never connected.

Under the same environment, websocket is successfully connected.
I refered an website and I put flash socket policy file accordingly like the below.

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*" to-ports="*"/>
</cross-domain-policy>

Do I need any other setting or sth?
