Inconsistency in pooled-but-unused TCP connection error between Windows and Linux/MacOs

thanks I am not sure this is achievable unless as you said you set an exception handler on the connection.

The pool itself does not interact with the connection exception handler, since the connection exists outside of the pool and one could set an exception handler on it and the pool would overwrite it.

as a facility, you can set a connect handler on the HttpClientBuilder that would facilitate the setup of such strategy instead of melting that in your request/response code

Thanks for looking at this, but can't we update the connection's exceptionHandler when it goes back to its pool, or as soon as the response is 100% read ?
Such exception handler could log the disconnection as warning instead of error since there will be no immediate issue with the connection being lost.

thing is that a connection can be partially in the pool like HTTP/2

[NilsRenaud]

I saw that HTTP/1.1 and HTTP/2 connections both have a notion of active stream, so I guess we could hook something here and update the connection exception handler as soon as this active stream count reaches 0.
What do you think ?
