System.security.allowDomain()
Availability
Flash Player 6; behavior changed in Flash Player 7.
Usage
System.security.allowDomain("domain1", "domain2, ... domainN")
Parameters
domain1, domain2, ... domainN
variables in the file containing the
formatted in the following ways:
•
"domain.com"
•
"http://domain.com"
•
"http://IPaddress"
Description
Method; allows SWF files in the identified domains to access objects and variables in the calling
SWF file, or in any other SWF file from the same domain as the calling SWF file.
In files playing back in Flash Player 7 or later, the parameter(s) passed must follow exact-domain
naming rules. For example, to allow access by SWF files hosted at either www.domain.com or
store.domain.com, both domain names must be passed:
// For Flash Player 6
System.security.allowDomain("domain.com");
// Corresponding commands to allow access by SWF files
// that are running in Flash Player 7 or later
System.security.allowDomain("www.domain.com". "store.domain.com");
Also, for files running in Flash Player 7 or later, you can't use this method to allow SWF files
hosted using a secure protocol (HTTPS) to permit access from SWF files hosted in nonsecure
protocols; you must use
Example
The SWF file located at www.macromedia.com/MovieA.swf contains the following lines.
System.security.allowDomain("www.shockwave.com");
loadMovie("http://www.shockwave.com/MovieB.swf", _root.my_mc);
Because MovieA contains the
variables in MovieA. If MovieA didn't contain this command, the Flash security implementation
would prevent MovieA from accessing MovieB's objects and variables.
