exactSettings (System.exactSettings property)
public static exactSettings : Boolean
A Boolean value that specifies whether to use superdomain (false) or exact domain (true)
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 in a
directory called here.xyz.com, the settings and data for a SWF file hosted at there.xyz.com are
stored in a directory called 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 in a directory called 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 in the xyz.com directory. If this isn't
the behavior you want, ensure 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, do so in the first frame of your
document. If you want to change this property from its default value, do so near the
beginning of your script. 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 the files published for Flash Player 7 share a single value
for System.exactSettings, and all the files published for Flash Player 6 share a single value
for System.exactSettings. If you use MovieClip.loadMovie() or
MovieClipLoader.loadClip() to load one SWF file into another, all of the files 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 the files that you plan
to load. If you load multiple files, the setting specified in the last file that's loaded overwrites
any previously specified setting.
