I am finding that if I load Flash from a HTTPS page (https://ssl.example.com/) and try to make a request within ActionScript 3 to http://app.example.com/ the request does not go through. Same goes for the opposite (accessing https from a http-loaded flash script).

The request is failing, the requested data (passed from a PHP script) is not loading.

Now at first I assumed the trouble was with cross-domain policy files, but I have fixed that issue (I think).

Is there any security policy in Flash (CS5 btw) on HTTP vs HTTPS requests based on where the script is loaded from?

Thanks!

    First, starting with Flash Player 7 https://www.mydomain.com/ ≠ http://www.mydomain.com/ and http://www.mydomain.com/ ≠ http://app.mydomain.com/ when working with crossdomain.xml policy files [reference]. So it is quite likely your issue relates to crossdomain configuration.

    If you’re going to be mixing protocols, you also need to add secure=false on the <allow-access-from> node that grants access to your SWF’s domain.

    You can find a helpful guide to crossdomain.xml files on Senocular’s website.
