Fired when a document finishes transferring.
The 'callback' is called when the 'EndTransfer' event is emited.
The argument 'e' has the following properties:
The EndTransfer event is fired first when the client finishes sending data to the server (in a 'POST' or 'PUT' request) and then when the document text finishes transferring from the server to the local host.
The Direction parameter shows whether the client (0) or the server (1) is sending the data.
