ClientSession cannot reuse connection pool about aiohttp HOT 4 OPEN

I filled in the wrong place
aiohttp Version -- 3.9.1
multidict Version -- 6.0.4

from aiohttp.

I debuged the BaseConnector.connect function, and found a suspicious point:
proto = self._get(key)
the proto always return None, and causes the connection to be re-established all the time

from aiohttp.

Many requests with the same URL and port are sent at the same time

Maybe you meant something else, but you can't send 2 requests at the same time with the same connection. So, if your description is accurate, then this is working as intended (i.e. the only way it could possibly work).

If you are sending multiple requests over time and have completed/closed the previous requests/responses (cleanly), then it should be reusing the connections.
