It is from actionscript documentation ( http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/Socket.html ):
- In Flash Player 9.0.124.0 and later, a socket policy file is required for any socket connection. That is, a socket policy file on the target host is required no matter what port you are connecting to, and is required even if you are connecting to a port on the same host that is serving the SWF file. - In Flash Player versions 9.0.115.0 and earlier, if you want to connect to a port number below 1024, or if you want to connect to a host other than the one serving the SWF file, a socket policy file on the target host is required. - In Flash Player 9.0.115.0, even if a socket policy file isn't required, a warning is displayed when using the Flash Debug Player if the target host doesn't serve a socket policy file. I use Flash Player 11.2.202.235 :) German. 2012/5/21 German Grekhov <[email protected]> > Sebastian, thanks for the response. > > Yes, I know it, and I try to connect exactly to the server which the swf > is from. > But anyway I receive the error. > > German. > > 2012/5/20 [email protected] <[email protected]> > > Bottom line is: You should not need that file except you are developing on >> different servers.
