=head1 NAME

referer2dlf - convert referer web server log file to www DLF

=head1 SYNOPSIS

B<referer2dlf> I<file>

=head1 DESCRIPTION

B<referer2dlf> converts Referer web server log files to the
www DLF. Referer log format was first implemented in the NSCA httpd server. 
Apache can be configured to log in that format. 

Note that if you want to log referer information, the combined log
format is a better format.

=head1 REFERER LOG FORMAT

The Referer log format logs the referer information in the following format :

 I<uri> -> I<document>

where the fields have the following meaning:

=over 4

=item I<uri>

The referring URI. This is the content of the Referer request's header
which usually reflects the page where the user was before that
request.

=item I<document>

The local document that was referenced by that URI. This is the
requested file without any query string.
