HTTP to HTTPS protocol access between SWF files

You must use an allowDomain handler or method to permit a SWF file in one domain to be accessed by a SWF file in another domain. However, if the SWF file being accessed is hosted at a site that uses a secure protocol (HTTPS), the allowDomain handler or method doesn't permit access from a SWF file hosted at a site that uses an insecure protocol. To permit such access, you must use the LocalConnection.allowInsecure Domain() or System.security.allowInsecureDomain() statements. See Allowing HTTP to HTTPS protocol access between SWF files for more information.
