This is partly off topic. I want to use a file reference to upload custom binary data (ie a file built within flash) rather than a physical file from my disk. Do you know if it can be done? I’m currently achieving it through a URLLoader object, but it has a huge problem: There is no upload progress events :/ I read the file reference does dispach this events, so I was wondering…. Any help would be appreciated.

While this is a little late to be useful, I figured for the web searchers like myself encountering this issue for te first time as well, that custom headers aren't the only way to get additional info to the server along with binary data.

Cookies are always sent along with requests, so if you setup an ExternalInterface method to update a cookie via JS, you can read the cookie data on the server side.

You are right. This is a real problems. The Filereference.upload doesn’t send any Header to the server if you don’t use IE with windows. All the information here:

jiayin: The above code is ActionScript 3.0 targeting Flash Player 9. According to the latest URLRequest.requestHeaders documentation still doesn't work with FileReference.upload.

I've had a look at the swfupload source code and I can't see anything in there that adds custom headers to a file upload.request.
