HTTPS, IE & Flex

I have an application that works fine over http. I push it into production and it runs over https, and it runs fine in firefox, but in IE none of the remoting calls work and there is no data to display. It doesn't go into a reloading frenzy, and I can click around the app just fine, but it's in essence broken because it loads no data.

I load the app in the browser via https and I loaded up Charles Web Debugging proxy and I do not see any https remoting calls to my ZendAMF php file being made thru IE. There are calls, but they just seem to be blank, but that always happens. I am assuming it's some kind of session setup within flex or something. Usually the 4th reference to my php remoting file is when it starts calling the methods I had setup to call. And the 4th call in Firefox is to my getUser method, but there is no 4th call to the AMF Remoting php file in IE.

And like I said, all the remote methods are called just fine in all browsers via http, and it works perfectly in firefox via https.

IE and https is where nothing happens; no data is loaded and I don't see any error messages. I don't know where to start. Help?

UPDATE: I see in this post it may have to do with cache-control, and have also heard that possibly the pragma: no-cache that I see in the HTTP headers. Any idea how I can adjust the headers that are returned to fix this problem?

Below is where I setup the remoting delegate for all Remoting Calls
