my_lc.allowDomain = function(sendingDomain):String{
return (sendingDomain==this.domain() ||
sendingDomain=="www.macromedia.com");
}
In the following example, a sending SWF file located at www.yourdomain.com invokes a method
in a receiving SWF file located at www.mydomain.com. The sending SWF file includes its
domain name as a parameter to the method it invokes, so the receiving SWF file can return a
reply value to a LocalConnection object in the correct domain. The sending SWF file also
specifies that it will accept commands only from SWF files at mydomain.com.
Line numbers are included for reference purposes. The sequence of events is described in the
following list:
•
The receiving SWF file prepares to receive commands on a connection named
The Flash Player resolves the name of this connection to
LocalConnection.connect()).
•
The sending SWF file prepares to receive a reply on the LocalConnection object named
