Testing content locally with Flash 8 local file
security restrictions
As a Flash developer, you frequently test Flash applications locally, so you might see a dialog
box prompt when a local Flash application tries to communicate with the Internet. You might
see this dialog box when you test a SWF file in Flash Player if the SWF file does not have
network access. For more information on publishing SWF files with specified permission
levels, see "Publishing files for local deployment" on page
one of these options means you can communicate with the network or the local file system.
At times, you might need to communicate with the local file system and the network when
you are testing a document. Because the new security model might interrupt your workflow
when you are authoring Flash applications, you can use the Global Security Settings panel in
Flash Player's Settings Manager to specify which Flash applications on your computer can
always communicate with both the Internet and the local file system. Or, you can modify the
configuration file to specify trusted directories on your hard disk.
For more information, see the following sections:
"Specifying trusted files using the Settings Manager" on page 688
"Creating configuration files for Flash development" on page 690
Specifying trusted files using the Settings Manager
You can specify what Flash content on your computer may always use the older security rules
by adding the location of the content to the Global Security Settings panel in the Flash Player
Settings Manager. After you add a location on your computer to the Security panel, content
in that location is trusted. Flash Player won't ask you for permission and is always allowed to
use the older security rules, even if Always Deny is selected in the Security panel. The Always
Trust Files in These Locations list overrides the options in the Settings panel. That is, if you
select to always deny local and web content the right to use the older security rules, the local
files in your trusted list are always allowed to use the older rules.
The Always trust files list at the bottom of the panel applies specifically to Flash content that
you have downloaded to your computer, not content that you use while visiting a website.
