Migrating a website from CentOS 6 ot 7. I try to fire up apache, and it
fails, complaining of a directive:
       CustomLog       logs/internal.oir.cit_ssl_request_log \
                        "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"

I'm googling, but I'd be happy if someone who knows apache more deeply
could tell me what's wrong with that - am I missing a package I need to
install, or had the directive syntax changed?

Thanks in advance.
