  #4562 <https://github.com/aio-libs/aiohttp/issues/4562>_

• Always make sure transport is not closing before reuse a connection.

  Reuse a protocol based on keepalive in headers is unreliable.
  For example, uWSGI will not support keepalive even it serves a
  HTTP 1.1 request, except explicitly configure uWSGI with a
  --http-keepalive option.

  Servers designed like uWSGI could cause aiohttp intermittently
  raise a ConnectionResetException when the protocol poll runs
  out and some protocol is reused.
