A sad note on 3.2.1.8
But not to be too sad, but I might as well tell you right now that File uploading support actually only applies to plain text document until a better method is discovered. Binary content doesn’t send well using the current method.
While it does do what it should, it fails early on during the send, giving a partial/header of a file rather than the complete one.
I hope you are not all disappointed at this, roadblock, to say the least.
If binary uploads are not solved by the time 3.2.1.8 is fully translated, partial uploading support will be added, while binary uploading content will be worked on.
There is a possibility that this is impossible for the current means, but there might be a workaround (I see a few possible workarounds).
