    #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.
