Content

The server asks for the content of the file by opening one channel; the client answers with the bytes as channel responses and the finish, or an error and the finish.

The server opens exactly one channel on the scope, once the temporary file exists: the content. The client answers on it with the bytes of the file.

• The request. The payload of the channel request is empty. Request states its form.
• The response. Zero or more channel responses carrying bytes and the channel response finish, or an error last. Response states the sequence.
• The scope answers after. The server sends the scope’s response only once this channel has finished.
