Flash Player 9 and later support policy file logging. The
policy file log shows messages for every event relating to policy
files like the crossdomain.xml file. This includes attempts to retrieve
them, successes and failures in processing them, and the fate of
the requests that depend on them.
The policy file log file is named policyfiles.txt. It is in the
same location as the trace log (flashlog.txt). For information on
where to find these log files, see Log file location.
To use policy file logging, you must use the debug version of
Flash Player. In addition, you must add the following to your mm.cfg
PolicyFileLog=1 # Enables policy file logging
PolicyFileLogAppend=1 # Optional; do not clear log at startup
For more information about editing the mm.cfg file, see Editing the mm.cfg file.
To test if you are logging policy file log messages, open any
SWF file with your debug player. The application does not need to
use a policy file, or even be running on the network. In the log
file, you should see at least one message indicating that the root-level
SWF was loaded.
