Dear Maintainer, after upgrading from stretch to buster, some scripts using cURL wwere failing. I think I traced it down to the curl bug 3676: https://github.com/curl/curl/issues/3676 Cookies from a cookie file are not sent to the host when the host is a dotless hostname, i.e. http://testhost/ The bug is fixed upstream but the change appears to not have made it into the Debian build. I would be great if the fix could be incorporated into Debian stable.
