New security model and legacy SWF files

Rules for how Flash Player determines whether two domains are the same have changed in Flash
Player 7. In addition, rules that determine whether and how a SWF file served from an HTTP
domain can access a SWF file or load data from an HTTPS domain have changed. In most cases,
these changes won't affect you unless you are porting your existing SWF files to Flash Player 7.
However, if you have SWF files published for Flash Player 6 or earlier that load data from a file
stored on a server, and the calling SWF file is playing in Flash Player 7, the user might see a dialog
box that didn't appear before, asking whether to allow access. You can prevent this dialog box
from appearing by implementing a policy file on the site where the data is stored. For more
information on this dialog box, see
models" on page
You might also need to implement a policy file if you are using runtime shared libraries. If either
the loading or loaded SWF file is published for Flash Player 7 and the loading and loaded files
aren't served from the exact same domain, use a policy file to permit access. For more information
on policy files, see
