The header passed to the server is, in fact, HTTP_REFRERER. Here's
an example of the entire environment requested in a GET from a local page on
http://localhost/index.pl on my laptop.

In perl, you can get that by doing the following:
use Env;
use CGI qw(:all);
print "<!--\n";
foreach $parameter ( sort keys %ENV ) {
print "$parameter is: $ENV{$parameter}\n";
}
print "-->\n";
/d
