5.3.3 HTTP Referer Log (WLGRFL) File

The HTTP Referer Log (WLGRFL) File is derived from the HTTP
Referer Log.  It provides information about web pages that
referred (linked to) the requested web page.  The file
contains event data that is logged every time an entry is
logged in the Access Log.  The information contained in the
file are who referred the web page, what web page was
requested, and when the web page request was made.

The WLGRFL file, by default, is turned off at the DETAIL
time-span.  The majority of the links to the web pages could
be made from the local server where the web pages are stored,
thus making the file more voluminous with information that
may not be desirable.

The HTTP Referer Log data, along with the data from the other
logs, help you rank specific web sites based on their
referral frequency.

The following sections describe the file organization, list
data elements maintained, and provide usage hints.
