- degraded mode where CURLOPT_FRESH_CONNECT is enabled on every HTTP

I'm having an issue in this mode when the server responds with "HTTP/1.1 401
Unauthorized" to a GET request I just performed. In that case, libcurl is
internally performing an HTTP request to send the authorization; and that
request is made using an already existing connection somehow ignoring the
FRESH_CONNECT option I passed to the original request.
Is there a way I could force libcurl to open a new connection also when it
performs a request internally (generally or at least when handling 401)?
Thanks for this report!
Presumably you're also using NTLM or Negotiate authentication too where
disconnecting is really breaking things?
But no, we don't have any external way to change this behavior. I would rather
consider this a bug that we should handle ourselves without the application
having to do anything at all about it. There's code in libcurl that attempts
to act "correctly" when then apparently isn't enough?

Can you figure out why?
Do you have any public URL we can reproduce this on?
Also, please post this as an issue on github
(https://github.com/curl/curl/issues) so that we don't forget about it!
