This is not how http works.

Your cron script will need to make a http request to your other server and trigger the worker script there. The easiest way is to use LWP::Simple :

use strict;
use LWP::Simple;
my $url = 'http://www.example.com';

get $url
  or die "Couldn't retrieve $url";

Your script simply did one thing, as you witnessed already, it just printed out the location, which does not accomplish anything unless you are a browser that interprets the Location: header as something to act upon...
