Fast! You'd like to download a video from somewhere to put on your brand-new whatever-pod, and you discover that the VideoDownloader in your Firebox doesn't work any more! Well, you can be sane and install something more updated, or you can go Perl with HTTP::Proxy!

#!/usr/bin/env perl
use strict;
use warnings;
use HTTP::Proxy;
use HTTP::Proxy::HeaderFilter::simple;

$|++; # no buffering on STDOUT please

my $proxy = HTTP::Proxy->new(@ARGV);
$proxy->push_filter(
   request => HTTP::Proxy::HeaderFilter::simple->new(
      sub { print {*STDOUT} $_[2]->uri(), "\n" }
   )
);
$proxy->start();
[download]

Start the proxy in your computer, point the browser to the proxy (it binds on port 8080 by default) and you'll have a list of all visited URIs... included the ones you're really looking for.

Good job, BooK!
