When using this method, consider the Flash Player Security Model:

For Flash Player 8:

• If the SWF file to be called is in a sandbox that can only interact with the content of the local file system, and the target resource is from the network sandbox, data loading is not allowed.
• If the SWF file to be called comes from the network sandbox and the target resource is local, data loading is not allowed.

For more information, see the following section:

• Flash Player 9 Security White Paper in http://www.adobe.com/go/fp9_0_security_cn)
• Flash Player 8 security-related API whitepaper in http://www.adobe.com/go/fp8_security_apis_cn)

For Flash Player 7 and later versions:

• A website can use a cross-origin policy file to allow cross-origin access to resources.
• In any SWF file running in Flash Player 7 and later versions,URLMust be in the same domain. For example, SWF files at www.somedomain.com can only load data from sources that are also at www.somedomain.com.

If the SWF file is running in a player earlier than Flash Player 7URLIt must be in the same super domain as the SWF file that issued this call. A super domain can be obtained by deleting the leftmost component of a File URL. For example, the SWF file at www.somedomain.com can load data from the source at store.somedomain.com because both files are in the same super domain named somedomain.com.

This method worksXML. sendandload ()Similar.
