Do you need streaming (i.e. transfer of humonguous data amounts) both on the request and response? Or just on the response (typically: downloading a file or large data set)?

The "Streamed" setting will stream both ways - both the request going to the server, as well as the response from the server, will be streamed. More often than not, that's not the ideal scenario.
