Transfering over 100MB file #7

I am trying to upload file whose size is over 100MB with your library.

But every time I try to upload, browser show error 'Failed to send WebSocket frame'.

So I try to slice file with ArrayBuffer.slice method and write data of chunk to stream, but this time, server show me unknown error :/

Is there any code example that make chunks with data and send them progressively?

Thank you.
