I met issue when transfer iso, qcow2, raw file from browser.

[silentbalanceyh]

I have copied the source of UploadFileHandler and call startUpload method here, but I met issue that the transferred byte is 0.
The browser console is:

It seems that deadlock when I call PUT /image/{ticket-id}, I'm sure the code is correct when I call uploading, and the image ticket has been created successfully. But when I call xhr.send chunked request, it seems that the bytes are not sent to remote here. I used ovirt-engine GWT to send the request. Could you help to investigate this issue and It blocked my project.

But when I call xhr.send chunked request

Chunked encoding is not supported in ovirt-imageio server. Check how the current javascript code is uploading data.

If you build something on top of ovirt you should use ovirt-img command or the ovirt_imageio/client python package. This provides the best performance and features that can never be available in a browser.
