Simple repro: >curl -vI --http1.1 https://example.com/[1-3] -H"Connection:close"
output of the old CURL version contains "* SSL re-using session ID"; output of 7.77.0 does not. Wireshark confirms that the old version sent PSK in client hello, the new version did not. curl 7.77 downloaded here: https://curl.se/windows/dl-7.77.0_2/curl-7.77.0_2-win64-mingw.zip Regards, Daniel ------------------------------------------------------------------- Unsubscribe: https://cool.haxx.se/list/listinfo/curl-library Etiquette: https://curl.se/mail/etiquette.html
