Hello, I've come across something strange. ?When using openssl s_client and trying to send B (uppercase only) as the first character on any line it causes a heartbeat to be sent. ?Is this a bug or a feature? ?Any way to escape it to send the uppercase B without sending the heartbeat? ThanksRob openssl s_client -connect www.google.com:443 -------------- next part -------------- An HTML attachment was scrubbed...
