Authoring: Flash MX 2004.
Playback: SWF files published for Flash Player 6 or later, playing in Flash Player 7 or later.
System.exactSettings
Property; specifies whether to use superdomain or exact-domain matching rules when accessing local settings (such as camera or microphone access permissions) or locally persistent data (shared objects). The default value is true for files published for Flash Player 7 or later, and false for files published for Flash Player 6.
If this value is true, the settings and data for a SWF file hosted at here.xyz.com are stored at here.xyz.com, the settings and data for a SWF file hosted at there.xyz.com are stored at there.xyz.com, and so on. If this value is false, the settings and data for SWF files hosted at here.xyz.com, there.xyz.com, and xyz.com are shared, and are all stored at xyz.com.
If some of your files set this property to false and others set it to true, you might find that Swf files in different subdomains share settings and data. For example, if this property is false in a SWF file hosted at here.xyz.com and true in a SWF file hosted at xyz.com, both files will use the same settings and data—namely, those at xyz.com. If this isn't the behavior you want, make sure that you set this property in each file to correctly represent where you want to store settings and data.
If you want to change this property from its default value, issue the System.exactSettings = false command in the first frame of your document. The property can't be changed after any activity that requires access to local settings, such as System.ShowSettings() or SharedObject.getLocal().
If you use loadMovie(), MovieClip.loadMovie(), or MovieClipLoader.loadClip() to load one SWF file into another, all of the files published for Flash Player 7 share a single value for System.exactSettings, and all of the files published for Flash Player 6 share a single value for System.exactSettings. Therefore, if you specify a value for this property in one file published for a particular Player version, you should do so in all files that you plan to load. If you load multiple files, the setting specified in the last file loaded overwrites any previously specified setting.
