I'm not about it.
server-first keyword deprecated in 3.5.x.
AFAIK, keywork "bump" now has yet another meaningful.
And also: in your example can only use acl "all". Any other ACL's
leading "Bungled config line" error.
I.e, for example,
acl net_bump acl net_bump src 192.168.101.0/24
ssl_bump peek step1 net_bump
ssl_bump server-first step2 net_bump
breaks configuration.

transparent with no browser errors in 3.5.1 by using the following. If I
understand correctly, this is actually whats required to mimic the
