Double sendBody in DataResponse

[andyvanosdale]

Just curious, is this supposed to call sendBody with an empty Data? I don't see any comments around it why it would do that.

https://github.com/envoy/Ambassador/blob/master/Ambassador/Responses/DataResponse.swift#L81

            if !data.isEmpty {
                sendBody(data)
            }
-->         sendBody(Data())

Nevermind... #19 answered my question.

@enozero sending an empty data means EOF (end of file), or close the connection.

As you may want to send data chunks, at one point you want to tell Embassy to close the connection, then you send an empty data.

That makes perfect sense. Thanks!
