I'm surprised I'm having trouble with this, since it seems such a straightforward concept. I have a PHP web service which acts as an API/backend. The clients take many forms - flex/flash, iPhone apps, etc.
The problem I'm having is that the crossdomain.xml does not seem to be working. The Flex clients running on the same server as the API work fine, but otherwise I get a security error. I should mention I am using HTTPS, though I have tried using HTTP and still get the same error.
Here's the crossdomain.xml file:
And here's the PHP script that is erroring out when I try to connect to it with a URLLoader:
Thanks for all your help.
