[thelist] cgi redirection based on referrer

[Gustavo Arizpe]

I have a parked domain in my main hosting account, and a cgi program for
redirecting depending on the accesed domain, as follows:

______
#!/usr/bin/perl

$server = $ENV{'HTTP_HOST'};
if ($server eq "usabilidad.org" || $server eq "www.parkeddomain.com") {
    print "Location: http://parkeddomain.com/somedirectory/\n\n;
    exit;
}

else {
    print "Location: http://$server/index.shtml\n\n";
    exit;
}

print "Content-type: text/htmlnn";
________


How can I make this cgi to redirect depending on the URL referrer, for
example, I'd all my visitors from google to be taken to some directory?

Thank you so much.
