    This question would probably be more apropriate to a discussion forum related to your webserver. However, in the spirit of Perlmonks I offer you a short perl/CGI script that will show you all the environmental variables that are available so you can see if you can find one that suits your needs. 
    #!/usr/bin/perl -w
use strict;
use CGI qw(:standard);
print header,
  start_html(-title => 'ENV vars', -bgcolor => 'white');
foreach (sort keys %ENV){
  print "<b>$_</b> -> \"$ENV{$_}\"\n<br>\n";
}
print   end_html;

      Or the non-CGI.pm version of the above...
      #!/usr/bin/perl

print "Content-type: text/html\n\n";
print "<html><body><pre>\n";
foreach (sort keys %ENV) {
    print "\$ENV{$_}\t$ENV{$_}\n";
}
print "</pre></body></html>\n\n";

    Or the exact names of some of the variables:
    HTTP_HOST i.e. "some.where.com"
    REQUEST_URI i.e. "/page/file.cgi"

    /Maqs.
