I got:

But still when using:

use LWP::UserAgent;
  $ua = LWP::UserAgent->new;
  $ua->default_header('Accept-Encoding' => scalar HTTP::Message::decod
+able());

  $ua->add_handler("request_send",  sub { shift->dump; return });
  $ua->add_handler("response_done", sub { shift->dump; return });

$ua->get($mech->uri);

I get:
