Our flex app makes multiple backend calls for loading single webpage. Each call goes to database, that takes some processing time. We were using RemoteObject with my-amf. We could make our app send multiple requests at a time by setting distinct endpoints for each request. But, we found that in IE, we can have only 2 requests at a time. And we don't want to change registry for overriding this. So, we changed to RemoteObject with my-rtmp. But, now it looks like requests are being executed serially. We tried setting concurrency to multiple.
Any idea what is happening ? We are using FDS 2.0.1.
