+  This directive specifies the log format string that will be used for all logs
+  resulting from traffic passing through the frontend using this line. If the
+  directive is used in a defaults section, all subsequent frontends will use
+  the same log format. Please see section 8.2.4 which covers the log format
+  string in depth.
