I tried to get the source of the page included in the page "http://www.salvasms.it/mostracat.php/" by the iframe:

<iframe frameborder="no" framespacing="0" scrolling="Auto" border ="0"
+ width=470 height=500 name="principale" src="http://www.salvasms.it/l
+egric.php?pag=&dataric=" scrolling="auto">
[download]

With firebug i can see the part of the source, but with WWW::Mechanize and WWW::Mechanize::Frames i can't do it!!

This is my script:

#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;
use WWW::Mechanize::Frames;
use HTTP::Cookies;

{# ridefinisco la set_cookie, in modo che non cestini i cookie "scadut
+i"
 my $orig=HTTP::Cookies->can('set_cookie');
 *HTTP::Cookies::set_cookie=sub {
     $_[9]=undef;
     goto $orig;
 }
}

my $mech = WWW::Mechanize::Frames->new();
$mech->agent_alias('Linux Mozilla');
my $cookies=HTTP::Cookies->new(ignore_discard=>1);
$mech->cookie_jar($cookies);

my $url = 'http://www.salvasms.it/entra.php?userid=user&password=s3cre
+t';
$mech->get($url);

#print 'Url: ',$mech->uri(),"\nCookies: ",Dumper($mech->cookie_jar);

my @frames = $mech->get_frames();

#print "Frames: @frames\n";

print $frames[0]->content;

#print $mech->content();
