Choose a file I want to upload (like using FileReference). Then flash (flex/air?) will split file to - for example - 1MB chunks and these chunks will send (post method) to server? (server will then join chunks to original file). I don't want desktop-like application using air but small swf file that will load as object to html page providing upload functionality.
I know, that flash (neither flex) can't access local files he choose. But file I choose to upload is accessible. Problem is that FileReference class don't have method to byte-oriented reading from file.
I think facebook has functionality like this. When you upload large video, it will do multiple requests to server.
