Slog
SSLLog filename Server config, virtual host Apache v2 only
This directive sets the name of the dedicated SSL protocol engine log
file. Error messages are additionally duplicated to the general
Apache error_log file (directive
ErrorLog). Put this somewhere where it cannot be
used for symlink attacks on a real server (i.e., somewhere where only
root can write). If the filename does not begin
with a slash (“/”), then it is
assumed to be relative to the Server Root. If filename begins with a
bar (“|”) then the string following
is assumed to be a path to an executable program to which a reliable
pipe can be established. This directive should be used once per
virtual server config.
