Flash - Loading data from HTTPS server
The sitch:
You have a Flash SWF file on server http://www.somewhere.com. You are trying to load data with a Loader or URLLoader from an SSL server https://www.anotherplace.com. You have set up your crossdomain.xml file on anotherplace.com to allow-access-from domain www.somewhere.com.
The bitch:
You get a sandbox security error and it fails to load. But your crossdomain.xml looks fine. What’s wrong?
The solution:
Simply add secure = 'false' to the allow-access-from element pointing to the non-SSL http domain. So it’d be something like <allow-access-from domain = 'www.somewhere.com' secure = 'false' />
