To enable secure swf-to-server communication with secure server-to-swf replies, you may want to use the sendAndLoad method of the LoadVars class to send an SSL encrypted request to a server.
My tests have shown that if you use the sendAndLoad method (implying that you expect a reply from the server) and want to send to an https address e.g.
that the swf that's making this request must ITSELF have been served via https.
I'm trying to get confirmation that this is correct.
Attempting to use sendAndLoad to an https address from an swf that itself is served via http seems to cause an immediate IO error when the attempt is made
