Returns how many bytes of the response body have arrived. For a request given <a href="http-save_to.html"><code>Http.save_to</code></a> it is updated live while the request is pending — the bytes already written to the file — which is what a progress bar reads. For an ordinary in-memory request it is <code>0</code> until the reply lands, then the body length. <code>0</code> before <code>Http.send</code>.
