Romain Manni-Bucau commented on HTTPCLIENT-2024:
------------------------------------------------
[~olegk] I don't hijack an issue, I get exactly the same issue than this one,
I'm just aiming for a proper solution. Disabling pooling is one I propose but
is not possible today. Once again the env is what it is, the server does not
send Connection so the client pools the connection and there is no value in the
pooling manager - only one usable by concurrent apps since the other one is
about a single connection and poorly behaves in such env - which enables to
disable the pooling. 1ns does not mean the env is fucked up but that we got an
unlikely fast reuse - which happens on "big" machines. Also note that this
wouldn't be a solution but just a workaround since we use the fact 1 is close
to 0 whereas 0 would be "disabled" and 1 is "enabled" so totally different in
terms of reliability. Having a PerRequestConnectionConnectionManager would work
too for me BTW. I just need a not hacky way to not reuse connections when
server can't be fixed (and is a cloud vendor for ex, I don't have access to all
machines yet ;)).
