Safe and Dirty Remote XMLHttpRequest Sometimes we need XMLHttpRequest work on diferents domains (cross domains) a simple solution, you need JavaScript and Perl:

The XMLHttpRequest(); example:

var req = new XMLHttpRequest() // IE7, Firefox, Safari, Opera
req.open('GET', 'http://localhost/cgi-bin/remote.pl?url='+url, false);
req.send(null);

To make the remote request work, use remote.pl:

#!/usr/bin/perl
use LWP::UserAgent;
use CGI qw(:standard);
print "Content-type: text/plain\n";
my $url = param ('url');
$ua = LWP::UserAgent->new;
$ua->agent("Mozilla/8.0");
$req = HTTP::Request->new(GET => $url);
$req->header('Accept' => 'text/html');
$res =$ua->request($req);
if ($res->is_success) {
	$page = $res->content;
} else {
	$page = "error";
} print $page;

This is only a example:

Write a remote url and press the Remote button! / Escribe una direccion web remota y preciona el boton Remote The remote.pl could be much better implement (GET and POST methods, params and theirs values).
