Log File for HTTP Referer Header Fields (Deprecated)
Syntax: RefererLog A
Example: RefererLog logs/referer.log
Since: Apache 1.0
This directive specifies of the file to which the server
will log the HTTP Referer header field of incoming requests.
It has been deprecated, however, and you should use the
CustomLog directive with the ``%{Refer==er}i'' format string
instead.
