Question

Is it possible with a cross-domain policy file for use with Flash/AS3 to specify a blacklist? i.e. allow all URLs except the ones listed? So far I have only used it with whitelisting.

Was it helpful?

Solution

The specification appears to only support whitelisting; all settings are of the form "allow-access-from", not "deny-access-from".
