Socket connection PHP<>Flash

programming
1

Hello,

i build a working Socket connection between PHP and Flash.
Starting the Server an connect with Flash, works fine.

I also can send and recieve data from Flash to PHP to Mysql
and back. But if i close the Flash movie and start it again,
Flash try to connect…the policy message pops out and
then the Server connection get lost.

I think there is an problem with the socket_close and if a client
stops the connection, and reconnect again, the server tries to
close him self.

I hope someone can help me.

Sorry for my english :wink:
