Hi, I'm running Squid 4 beta. # squid -v Squid Cache: Version 4.0.17-20170122-r14968 I tested the following where Squid is listening on port 443 in accel mode. # echo "R" | openssl s_client -connect 192.168.101.2:443 2>&1 3>&1 | grep RENEGOTIATING RENEGOTIATING How can I disable client renegotiation?
