+Content-Length header
+=====================
+
+## Response without `Content-Length`, but with body
+
+The client should wait for the server's EOF. That is, when
+`Content-Length` is not specified, and `Connection: close`, the end of body is
+specified by the EOF.
+
+_(Compare with APACHEBENCH_GET)_
