Hi sometimes flash sent strange "policy-file-request" on websocket port. I am use tcpick for sniffing:

    # /usr/sbin/tcpick -a -C -yP "port 4005"
    11     SYN-SENT       browser:2192 > server:4005
    11     SYN-RECEIVED   browser:2192 > server:4005
    11     ESTABLISHED    browser:2192 > server:4005
    <policy-file-request/>.
    11     FIN-WAIT-1     browser:2192 > server:4005
    11     TIME-WAIT      browser:2192 > server:4005
    11     CLOSED         browser:2192 > server:4005

That is sent by the Flash player to get authorization that it is allowed to connect to that port. It does that when you aren't running a Socket Policy File server on port 843. See here: http://www.adobe.com/devnet/flashplayer/articles/socket_policy_files.html

If you use web-socket-ruby: http://github.com/gimite/web-socket-ruby it handles Flash Socket Policy File request automatically. Otherwise you need to handle the request at port 843 or the same port as the Web Socket port.
